OS/2 2.0 reminder

Fri Jul 31 12:23:41 EDT 1992

Just a reminder to those folks who were thinking about upgrading to
OS/2 2.0.  The $49 special upgrade offer from Windows to OS/2 2.0
expires TODAY.  DOS to OS/2 upgrade special price of $99 also
expires today.  Call 1-800-3-IBM-OS2 to order, or call your local
software dealer.  Even if you don't yet have a 386SX machine or
better, you might as well get the software now so you'll have it
when you finally upgrade to better hardware.

I have been using OS/2 2.0 for the past three months.  It's great
if you have a fast machine and enough memory (IBM says 4MB minimum,
I say 8MB minimum).  K1EA is using it too.  OS/2 is great for testing
DOS programs:  if they crash, you just close that DOS window and
start up a new one.  No need to reboot your system five times a day.

It's fun to have packet up in one window while you download
a new copy of CT in another, watch Geoclock in a third, and
print QSL labels in a forth.

CT doesn't send CW correctly when running under OS/2, so I usually
boot DOS during a contest.  You can switch back and forth just by
saying BOOT /DOS or BOOT /OS2 (this is the "dual boot" feature of
OS/2).

Under OS/2, the CW sending gets garbled because, being a true
preemptive multitasking operating system, OS/2 takes time slices
away from running tasks periodically to let others get some CPU time.
Ken and I hope to figure out a way to get around this problem,
possibly with a high priority device driver.

Throw away our DOS memory extenders (QEMM, EMM386, etc.)  Each VDM
(Virtual DOS Machine) sees as much Extended, Expanded, or DPMI (DOS
Protected Mode Interface) memory as you want (it's virtual memory).
It also runs Windows 3.0 software such as N6QR's VPLOT just fine (no
need to have Microsoft Windows installed).

The only DOS program I couldn't get to run in a VDM was CT386,
but Ken has a fix in the works for that problem (there was problem
with the memory routines used by the Zortech compiler).

Speaking as someone who normally has a really weak station at her
disposal, I have to strongly disagree with Trey on that last statement.
I have enough trouble trying to compete with everyone else in one
call area, much less everyone else on the continent. And in fact,
even when they go by districts I'm often not successful. :-)  I keep 
hoping that someone will call for "Six Bravo YLs".  :-)

I do agree, however, that we should call based on the district we're
actually operating in. Otherwise, as Trey notes, differing propagation 
could throw a real monkey wrench into the proceedings. (Well, it
wouldn't matter much in smaller countries, but it sure would here.)

Goodness, Trey, you're getting really kulchured since you moved

Subject: Going by district
Message-ID: <mailman.5.1043801126.8266.cq-contest at contesting.com>

A novel approach that I only heard used once seems worth an
experiment.  Instead of going by call districts or by geographical
area, ask for stations by "the last letter of your call."  Instead of
shrinking the pileup by 1/10th, it is shrunk by 1/26th (2.6 times
smaller).  The smaller the pileup, the quicker stations can be worked.
It is easy to explain (on phone), it goes in a predictable pattern, it
is fairly difficult to cheat (though someone is bound to sign
"portable Alpha!"), and it gives most everyone a fair shot.  The
stations with good propagation are going to get through first, but
they should all be worked quickly and then the weaker stations should
get through.  When no more stations remain (or if all that remains
is inaudible weak ones), it is time to move on to the next letter.

The one time I listened to a guy do this (simplex), it seemed to work
spectacularly well.  If anyone has a chance to try it while on a
DXpedition, let us know how it works!

I believe the primary cause of policemen, yakkers, and other
avoidable QRM is pileup frustration.  Nothing raises pileup frustration
more than listening to some rare DX spend hours on 1s, 2s, 3s, 4s, and
5s, completely missing the 45-minute West Coast opening.  Another
cause of pileup frustration is "I'll work five stations per call
district and then move on to the next."  Arghhh!

Anyway, I'm just glad my call isn't W0ZZ... (sorry John)

This discussion isn't directly related to contesting, so we should
probably QRT for now.  I mention it here because I think contesters
have the best shot at making it work.

HI Guys,

During tear down at FD we got into a discussion of what sort of maximum
rates are possible during FD on CW.  You really seem to be limited
by the low skill level of the stations you work.  We never got much
over 60/hr.

What peak rates have you hit on CW, and what band/power/antenna were
you using?

Operating K5BU during FD, I hit 110/hr on 15m CW early in the contest. I was
using CT, a TS-850 barefoot, and KT34XA at 40 ft. (class 1A). 
Location was Richardson, Texas, near Dallas. This rate was
sustained for only about 15 minutes at a time and seemed to be limited more
by conditions than other factors. A skillful operator should have been able to
boost that somewhat higher, I'm sure.

BTW, a thunder storm hit right at 1800 UTC and kept us off the air for an hour.
Then at 1030 UTC Sunday morning another storm hit with sustained 40 kt. winds
for 45 minutes. Our trailer mounted crank-up withstood it but I don't know how!
My tent was flattened. I sprinted 70 yds. to a secure structure and stayed put 
for 2 hrs until it passed. Our final score reflects the impact of mother nature.

Next year...

According to CT I was running over 100 Qs/hour a few times on 20
CW, but as the other gent observed, that only lasted for a few
minutes.  That was probably late afternoon/early eve on Saturday.
Some of it's skill level of those we work, no doubt about that.
But some of it's the fact that virtually everyone is running 100
watts (or less), so there aren't many standout signals that can
sit on a freq for hours as some do in SS, for example.  And there
aren't any multipliers, so people won't stick around to work you
if they don't get you on the first call.

We had some incredible rates on SSB as I mentioned in my previous
note.  We peaked over 200 a few times on 10 meters, and ended up
with 150+ for over 2 hours.

These ain't no big thing for folks like Trey, but it's kinda fun
for us mere mortals!

Some years back, WB5VZL and I were having a similar conversation
about what kind of rates were possible in Field Day, what with the
lid factor and all.  

So as a proof of concept (or whatever you choose to call it), 
WB5VZL, KM5X and I fired up N5TR in the 1987 Field Day with one
transmitter, a KW and beams in the Northern Texas section and 
made a lot of contacts.  After the event Geroge and I thought 
"that was interesting," so the next year we did it all over again, 
except with five watts.  This was interesting as well.

Anyhow, the numbers by hour and band for the 1987 effort are included 
below for the stout of heart.

Gary, I agree 100%.  Field Day CW is slow and grueling, but steady.  I know
I had some 50+/hour rates (both 15 and 20 CW, I didn't get a chance to try
40 CW), but I agree, more than 1/minute is tough to sustain.  Especially
with all the repeats, extra callsigns sent, etc.  I'll post our breakdown
sheet when I get a copy of it.

Hi folks,

I'd like to invite all Sysops of PacketCluster nodes to a new mailing
list _entirely devoted to_ to Dick Newell's PacketCluster Software.

What you have to do to get in it ?

send a message to listserv at ifsws1.sozialforschung.uni-stuttgart.de
with a message body of "help" - this is to show you the commands
this mailing list server supports.
Then, send a second message with a message body of
"subscribe packetcluster <firstname> <lastname> <(callsign)>"

so if you are Dick Newell and your callsign is AK1A,
the line would be:

subscribe packetcluster Dick Newell (AK1A)

Also I did open an anonymous FTP account on my machine to supply 
PacketCluster-related software, information files and databases.

FTP to 129.69.162.1, login as "ftp", choose any password.

Then "cd /pub" - that's where the things are.
Feel free to upload files to /pub/uploads, don't forget to leave a *.txt file
to describe your upload.

  OFFICE MEMO          Tuning a 4 Square                      Date:7/2/92
My wife's allowing me two free days in Wisconsin to tune W0AIH's 160m 4
square.  In summary, the design stuff was done similarly to the method
presented by Forrest, K2BT in Ham Radio back in '83:  The desired current
distribution is found using array theory, and serves as a known ( current
vector [I] ) when solving the linear system [V] = [Z] [I].  MININEC is used
to find self and mutual impedances, for a single element, Zii, and for the
mutual terms, Zij.  A math software package (you can do it by hand if you
want) such as Mathematica, or MATHCAD is used to solve for [V], from [V] =
[Z] [I].  The drive impedances to each tower are found by Zi = Vi/Ii.  I
used RF CAD Software SUPER COMPACT to design the network.  To confirm that
the solution is right, I re-applied the volage excitation solution from
Mathematica to a 4 square on MININEC (Method of moments software like NEC
solves for the current distribution by feeding the system known terminal
excitations).  The desired current distribution appears, which squares the
RF-CAD network solution.  Great theory, now for the hardware...and here's
the problem:

The towers are an odd length (185' -> ~1/3 wave length @ 160m), and closed
spaced (~.13 wave - the thing was originally designed for 80m).  The towers
are on a hill - not on level ground - and they are as much as 15 feet in
height from each other.  Lots of radials, but they're too short, and the
ground is low conductivity rocks and loamy soil.  Theoretical gain - even
measured - is OK, but to really tweak it in and get all of that gain & F/B,
we need to tune it.  One method would be to actually measure the self and
mutual impedances.  But we cannot simply measure them, given the coupling
among the array and scatterers nearby (Check your EM Green's functions,
that's rubbish about 1/4 waves being decoupled.  Anything out there is
coupled.)  The broadcaster's method is to sample the current of each tower
at the maxima, and compare the relative phases and amplitudes.  In our case,
the current maxima occurs at 55', making this the best spot to sample it. 
Anyways, last November, I installed current sampling coils on each tower at
55'.  I thought we'd have a great system to measure the relative tower
currents.  No, the system was corrupted by RF: a finger touch of the scope
and sampling coax connector would change everything.  I could not find any
chokes large enough to decouple the shield current, so I gave up.  We
operated the ARRL 160m contest, saw gain and some F/B, but not enough (But
it did work far better than Paul's elevated quarter wave, especially into
EU).  JAs heard (but not on the elevated), but not worked, hmmm (almost
embarassing to admit for a 4 square).  So, it seems it close, but not quite.
 Most of the contest was spent being jammed (25 hz off freq) by K3LID, and
saying "what if this damn thing worked right?"

Since December, I've pondered this problem, and I've decided that a current
probe at the tower bottom is better than none.  I've read a lot of applied
EM books and IEEE articles, and the best hand wave I've seen is that the
field is transitional at the base, forcing the current distribution on the
tower to be misleading.  The broadcasters say stick the probe at least 10 -
20 feet off the ground.  Despite that, they still recommend double shielded
coax, bonding to tower, and decoupling with that big choke again.  Stepping
over the fence at some local Minneapolis AM radio stations revealed that
they indeed go to all of that trouble.  My God, it's only ham radio, right?

We go with current probes at the base, along with Paul listening at his home
QTH (5 miles away), WA0PEV in his car talking back on 2 meters, K0KX in the
shack, and me in the dog house twiddling as I'm stung by wasps.  There's got
to be a better way.  Help!

It's only a hobby,
Steve, K0SF

Here's a few strange things I found trying out CT 8.09 for the IARU RS contest.
Could one of you New England guys pass this on to Ken ?

1)  When I enter a callsign and hit the space bar, I expect CT to figure
    out what zone the station is in, and fill in the zone field (just like
    it does for CQWW).  I should be able to change the zone field (in
    case it's a headquarters station).  Unfortunately, I have to enter the
    zone manually for every QSO.

2)  This is related to 1) above, but pretty bizarre ....
    I configured two computers to talk to each other running CT 8.09 as
    multi-single.  On computer 1, I enter the call JA3RL.  I enter the
    zone as "JARL".  I hit enter.  All is fine on computer 1.  On computer
    2, the call JA3RL is filled in correctly, but the zone is "45", not
    "JARL". 

Anyone know of other CT version 8 bugs related to IARU RS ?

What fun we had!
About d dozen contesters, mostly FRC members, and some YCCers, ran five
rigs at W1AW. 
Conditions were mediocre, and we had abt 5000 qso's.

Brutal static on 80 and 160 really hurt.  Too bad that 20 and 15 weren't as
good Saturday night as the were the previous 3 nights.  10 meters was
surprisingly good for this time of year - worked CT3BX and heard 5U7M

As you can see, I did not put in a lot of time. I thought that
conditions on 15 and 20 were excellent - the level of activity
out of Europe was amazing. Some nice surprises like VU2NBT and
S79KMB calling me on 15. P29DX on 4 bands and all of the HQ
stations made for an interesting contest. 15 was almost 
completely dead on Sunday, so it looks like we got lucky this

Message-ID: <7699 at jwh>

I talked to Dan Street, K1TO, this morning. He operated CW only
in the contest. Here's his breakdown:

Band      Qs   Mults

160        7     5
 80       31    17
 40      140    34
 20      642    53
 15      749    49
 10       25    12
Totals  1594   170  ==> 1.164 M

He was really happy with the first half of the contest (1050 Qs),
but was disappointed that things fell flat after 0500 on 20 meters
"and never came back." Summer conditions really blow sometimes.
Although he worked the DL and HA HQ stations on 10 meters, he said
that those Qs were skew-path (mostly south). The band certainly 
wasn't runnable into Europe from New England.

Any other CW-only scores? Anybody hear N5RZ's numbers?

Nice scores from Colorado, Steve.

I don't know if Trey did it on purpose, but the CW Sprint results in the
July/August NCJ are shown in QSO order, without the usual by score order 
listing. I think that is a good way to do it; I'm in favor of removing
multipliers from the Sprints entirely, except that it is fun to moan

K6XO   Single operator, Single band (20 meters).

743 QSOs,  300 Multipliers (est),  600K (est).

I understand that this contest was not announced in CQ magazine.
There was a good turnout in Europe for this one and fortunately,
we had good propagation into Europe all weekend on 20. There
was also an amazing contingent of BY and BV stations, but the
HLs were non existent and the JAs were scarce (these are both
Olympic Games countries). K3WW and W5FO appeared to be most
active in the U.S. and no doubt are medal contendors. Very little
activity in South America - I did not hear zones 10, 11 or 12.
I listened up on 15 now and then and found some strong signals
coming in from Europe.

I have some limited experience with the new stuff.  I replaced the aircraft
cable overhead on my Mosley PRO_96 with a V struss made from the new Philly.
So far it seems to be working fine.  The jacket does sort of disfigure
when you tighten down the clamps, it doesn't give you a real secure
feeling.  They tell you the amount of torque to use when tighting the
clamps.  They also say to check the torque on the clamps periodically,
which can be a problem if you can't easily reach them.

There are (I'm told) other companies that make potting heads that can
be used.  Also, the Socket Blue potting compound still seems to be 
available.  But the cable clamp method is much cheaper.

Philly Resin has a little pamphlet that shows you how to install the clamps.
Texas Towers sent along the pamphlet when I ordered the Philly from them.

Hope this helps,

Subject: Low Pass Filters ?
Message-ID: <9207301848.AA17932 at ulysses>

I recently discovered that my Drake low pass filter was causing a
2:1 SWR, as seen from the rig.  I opened it up, but didn't see anything
obviously fried.  I notice that the Drake filter is rated at 1000 watts
maximum, though.

Has anyone found a low pass filter that was actually worthwhile in
reducing TVI ?  To be honest, I view the installation of a low
pass filter as a CYA measure.

Subject: Low Pass Filters ?
Message-ID: <9207302000.AA04245 at larry.sal.wisc.edu>

Industrial Communications Engineers makes a Low Pass Filter that handles 
plenty of power without getting warm, doens't upset the SWR much, and
has enough attenuation to pretty much guarantee no harmonics get through
it.  My Bencher filter also worked OK, but it got pretty warm  at 1200 W
output on cw.

I haven't found myself in a situation where the filter made much difference,
but I live in a very strong TV signal area.  I'm sure that in a TV fring
e area the average amplifier would produce enough harmonic power to
cause TVI without a filter.  Otherwise, it's a CYA measure to be sure,
but a cheap one.

I bought some low pass filters from B&W - the guy who took the order had never
heard of them until I gave him the part number and prices from their price
list. I tested them on a network analyzer, and they looked great - the 80M LPF
had a nice null at 7 MHz, etc., so I used them in my multi-2 in ARRL this
year.

The 15 M unit went up in smoke Sunday morning. I opened it up, and the input
coupling capacitor is a teenyweeny little dinky thing - no wonder it smoked
(I'm only using a "street-legal" Alpha 76A, so don't get the wrong idea).
Thank God for 1/4 wave stubs.

I sent the 80/40 M filters back to B&W (at $40 each, I decided it was worth
getting my money back, and they gave me a refund). They don't make a 20M
filter. I'm going to build a set of KW bandpass filters from scratch.

i have used the ICE bandpass filters and they worked GREAT at the 
n5au multi-multi.  they are well built and took the power with no
problems.  i checked them on a network analyzer and found them to be
everything that ICE claims.  

ICE also makes a 5kw (i think it is 5kw) low-pass filter that i also checked
on a network analyzer and it looked great.  i dont know what happned to it
but while hooking up the 10m station at n5au i found it to be open.
it was not open before the contest -- anyway i dont know what happned to it.
i returned it to its owner (n3bb) maybe he will tell us what happened to it.

i would think that the ICE low pass would be a great choice.  
as far as bandwidth and all it is everything that ICE claims. 

BTW steve (n2ic) i have a drake low pass filter that you can have.
that way you can have one on each radio during the ss contests this fall.
(it has the same problem that yours does) :-)

I bought 2 of the 6 kW ICE low-pass filters, before they even appeared in   
their catalog.  They are ruggedly made and come with an attenuation curve
from an HP network analyzer.  I plugged them in (one for each amplifier) and
they worked fine on receive but one of them would short out on transmit.  It
turns out the cover alignment was very critical.  It was very close to one
of the components.  Realigning the cover solved the problem.  I brought it
to the attention to Mike W9SU at ICE.  The older design low-pass filters
(such as B&W) do not have as sharp of a roll-off above 30 MHz as the newer
designs.  I put several of them on a network analyzer, and the one that 
looked particularly good was the AEA.  I opted for the ICE because of its
ruggedness (if rated for 6 kW, it should be undestructable at 1500 watts!).
Look for high attenuation around 40-45 MHz, where TV IF's lie.  That also
happens to be where the TS-930 first IF lies, and I hoped that low-pass 
filter would also help in curing some IF interference between the two
TS-930's (it didn't...).

I wholeheartedly agree with VZL... the ICE bandpass filters work great.
N5HD and I built a pair of "boxes" with filters for each band and a
relay switching network.  'HD built a little interface box that follows
his '940 for bandchanges.  I built a interface box that follows my
Ten-Tec Corsair bandchanges.  We use these bpf's for multiop's at K5OJI.
However, since they are rated for only 200 to 300 watts, we use them
between the rigs and the amps.

To give a better picture of how these filters have helped us, imagine a
pair of 70' towers only 40' apart.  Now imagine a tribander on each of
the towers at 71', and on one of the towers, a 2 el 40 at 80'.  Throw in
a few dipoles for the other bands.  Before the filters, the second rig
was useless when the first rig was transmitting.  It would practically
jump when the other rig was keyed.  With the filters, either rig can be
on any band that the other rig is not on.  The ONLY time each rig can
hear the other is at the 2nd harmonic, and even then, it only sounds
like a strong signal.

A funny thing happened during Field Day at K5OJI when I was on 20 cw,
and thought my freq was trying to be taken away.  A couple of hundred Hz
below me was a loud station calling cq.  It was the 2nd harmonic of our
other rig on 40 cw.  Weird being QRM'ed by a station with the same call
as you.  A quick shout to the other op to qsy cured the problem, and
kept my 70 q/hr run going.

I have the ICE lpf at home.  These things are brutes.  I cannot verify
the 5Kw rating.  I have opened them up, and they look like they will
take it.  This filter has made a big difference in reducing tvi at home,
where I run the Corsair barefoot.

A hint for you multi-transmitter fans...

At K1EA, there was a nagging problem with TS-940s on different bands talking
to each other. It was strange - the signal was perfectly tuned in, no matter
where the receiving radio was tuned. The culprit turned out to be leakage of
the 49MHz first IF out the antenna terminal - a few milliwatts is perfectly
audible through the reciprocal (receive) path. Any old lowpass filter kills
the problem - and it can be between the rig and amp, so it doesn't have to
handle a KW - it just has to have a lot of attenuation at 49 MHz or so. And
you only need it on one radio in a multi-2!

I had the same problem in my multi-2, and DIDN'T find the problem - K1EA
and KM3T get credit for the solution - my solution was to substitute a 930 for
one of the 940s - that worked, too...

Subject: Upcoming DXAC vote on DX Operating Practices
Message-ID: <9207311458.AA03919 at us1rmc.bb.dec.com>

[NOTE:  Bill made a mistake in his description of working by call areas.
        I have made the necessary corrections, enclosed by [].  - AD1C]

DX-Operating Practices

The DXAC has been asked to vote on accepting the report on
operating practices on August 24. The subcommittee has worked
since 1990 to formulate a response to an ARRL BoD request to
research and recommend disqualification criteria for
DX-Peditions (sic). This request is based on concerns expressed
in the March 90 QST. The subcommittee is chaired by VE3HO, and
its members are K4MQG, K5YY, NA2M (replacing W2MT), W4VQ,
and W6CF. The report is lengthy, so there is obvious risk of
misunderstanding for me to attempt to summarize its main
points. Suffice it to say that this report is well-organized and
clearly written. It is evidently based upon careful consideration
of what is a complicated set of problems and an equally
complicated set of possible solutions. While some may object to
some of the conclusions, the subcommittee deserves everyones
thanks for tackling a thorny set of problems and doing a
professional job in presenting their suggestions.

The following are some of the highlights of the report:

1. DXCC Rule 12, Operating Ethics, provides a mechanism for
applying sanctions to individuals or DXpeditions who exhibit poor
operating practices, and that new disqualification criteria for
DXpeditions are NOT required or desirable at this time.

2. The DXAC shares with the BoD the concern that malicious
interference on the HF bands associated with major DXpeditions
is not desirable and is detrimental to the future of the amateur
radio service.

3. Operating Band Plan: This part of the report deals with the
possibility of an amendment to the band plans that recognizes
the need for designated space for DX-split frequency operations.
SSB and CW DXpedition and listening frequencies are suggested
for amateur bands 10 through 160M. Consideration is taken of the
operating privileges of US DXers with different classes of
licenses. No suggestions are made for RTTY. (There are no
surprises here insofar as I can see. Frequency ranges and options
correspond to those typically used by DXpeditions.)

4. Operating Practices and Procedures: This section is a
synthesis of the techniques and practices that most would agree
good DXpeditioners and successful, considerate DXers follow.
Several ARRL publications summarize many if not all of these,
but the report will serve to call attention to them.

When working by call areas, the recommendation to the
DXpedition operator is to ignore portable designation and
recognize only call sign prefix numbers. For example, if KC1AG
were in San Diego he would call with the [W1s] not with [W6s] or
BOTH the W1s and W6s. The report states this particular
recommendation is likely to be controversial. However, they
point out the rampant abuse of the portable designation as the
rationale for their suggestion. (Any comments?)

5. Equipment Manufactures: The report suggests the ARRL takes
steps to recommend to manufacturers that technical means be
developed to prevent inadvertent out-of-band and off-frequency
transmissions (e.g., transmitting on the DXpeditions XMIT
frequency.)

6. Enforcement and Education: As the report states, ...malicious
interference can to some extent be reduced by increased peer
pressure against such undesirable behavior and by more refined
enforcement techniques. Also suggested are educational
programs to help all amateurs understand proper operating
techniques for both DXpeditions and those attempting to work
them; mechanisms to provide public recognition to those who
exhibit superior and ethical operating techniques, etc.; and
development of a mechanism of alerting the ARRL FCC Auxiliary
Corps of major DXpedition activity. 

Due to the length of the report and the wealth of detail it
contains, I hope that this report will be published in QST and
thus be open for broad discussion. It deserves everyones
attention. I am also sure the subcommittee appreciated the
comments those on the YCCC PacketCluster submitted.

ICE Filter Performance Data
by Dave Pascoe KM3T

After the CQWW Phone multi-multi effort at K1ST, Steve Tolf (K1ST)
lent me his ICE (see ad in CQ Magazine) filters so that I could
measure their performance.  ICE manufactures a set of individual
bandpass filters (transceive) for you to install between your exciter
and amplifier.

I tested the 3.5, 7, 14, 21 and 28 MHz filters, in addition to the ICE
6kW lowpass filter.  The measurement results are summarized below and
in the photos showing the bandpass responses of the filters.

Data was taken with a Hewlett-Packard HP3585A Spectrum Analyzer.

Message-ID: <9207311517.AA21028 at ulysses>

For those of you looking for a low budget approach to interstation
interference for a multi-single or multi-2, here's what I do :

For each station,
I have built a simple wavetrap, consisting of a series circuit
of a variable capacitor and an inductor.  This wavetrap sits between
the rig and the amplifier, across the coax line (between center conductor
and ground).  The wavetrap capacitor is tweaked for the band that the
OTHER station is operating.  It serves two purposes:  it reduces the
overload caused by the other transmitter, and it reduces the phase noise
generated by the transmitter that interferes with the other station.

I find that careful tweaking gives me about 40 to 50 dB attenuation.

The situation here is almost as bad as K5OJI - 2 towers 70 feet apart,
about the same height.   Before I built the wavetraps, the phase noise
generated by my TS-940 when it was key-up (in the xmit position) on 10
meters, was S9+10 dB on the 15 meter receiver.  You can imagine how
many volts of RF was being pumped into the 15 meter receiver when I
had a KW output on 10 meters.

I know, this is a crude solution to the problem, but this is a low-budget
operation !

This is a good idea.  Since control of the bands is mostly in the
hands of the DXpeditioners, they are the ones who need to be educated.
Educating the people calling in the pileups is important, but secondary.
To wit, the 3Y5X operation was pretty much a joke, save for when F2CW
was at the key.  As long as the DXpedition is making QSOs, it is a 
success, no matter how much boorish behaviour the callers are able to
muster.

Rampant abuse?  I suppose the only possible way to really abuse the 
portible designation would be for me to sign WN4KKN when they are
taking 4's, WN4KKN/5 when they are taking 5's, WN4KKN/6 when they 
are taking 6's, etc.  If this is the type of abuse that people are 
concerned about, the DXpedition people need to find a better hash
than "call area."

Going by call areas is a poor operating practice in general, and 
asking K4TKM/6 to whip all the W4's to contact Egypt is absurd.  A 
much better practice is to hash things geographically, such as 
"QRZ North America" or "QRZ Europe."  Once again, this is really only
an issue for bad ops who travel.  These are the ones wasting everyone's
time taking the callers to task rather than simply getting the job 
(of making QSOs) done.  The good DXpedition op doesn't waste his time 
arbitrating; he just works guys.

Blah blah blah.  It's the ops who go on the DXpeditions who are the
root of most of the problems.  What is the League going to do, have
sanctions against lids who go on DXpeditions?  As I heard George
Fremin (WB5VZL) once say:  "*Anyone* can go on a DXpedition."  And
he's right.

Save yourself a toll call, ICE has an 800 number: (800) 423-2666.
I think they charge less than $30 a piece for the bandpass filters.

I have a set of 6 ICE bandpass filters.  They have worked pretty well,
though with only 15-25 dB of attenuation between some bands, I still
see some interstation interference.  All antennas are mounted on a
single 14' mast, so I have what you might call a worst case scenario).

I have found insertion loss to be rather high on 20m and 10m, much
higher than the figures reported here earlier (100w in, <80 watts out).
Of course, this was measured with a wattmeter, not a spectrum analyzer.
But could there be 10-20 watts in harmonics?  I'm using two TS-930Ss.
