Had one reply to my question on what the subject software does.  Basically,
its a voice keyer that you pre-record using .wav files.

The function keys then initiate the specific .wav file, I.E, CQ, QRZ ect.

I think I will stick to my DRU in the TS-850 and build the interface so the
the function keys will initiate one of my 3 voice memories.

At K2UA we put up some new wires for 80M.  Fed with 450 ohm ladder line
(black pvc with windows).  Works great, until it rains.  Then signals go way

We tried to improve its wind survival chances by lacing a support rope (3/16
dacron) every tenth hole from the feedpoint to the ground.  We didn't want
to leave the stuff unsupported.  Is the wet rope what makes it die in the
rain?  If so, what are the alternatives to this support method?

Or you can look at the radio catalog at:

Includes not only Amateur stuff but swl, am, fm etc.  Includes
a MUF caculator based on locations you specify for the transmitter
and receiver.

I built my own ladder line which does not seem to suffer from tuning
changes or losses in the rain.  I used #12 stranded, pvc jacketed wire
and solid acrylic rod for spacers.  The spacers are about 3/8"
diameter, 5-1/2" long, and placed about every 3 feet along the
feedline.  The ends of the spacers are notched so as to cradle the
wire.  A small hole is drilled near each end, and a short piece of #20
solid copper goes through the hole and is twisted around the #12
feedline wire on each side of the spacer to hold things together.  
This has been used on my 80m half-wave for about 7 years and has held
up very well.

Another benefit to using the #12 wire is that you have much less ohmic
loss at high current nodes.  I use this same antenna on 160m, where
the feedpoint impedance is something like 5 - j2000.  In other words,
the real part is very low, the reactive part is very high, and you end
up with extremely high voltage and current on the feedline (90 degrees
out of phase).  When I first tried 160m with the 450 ohm commercial
stuff which is #18 copperweld, the feedline got so hot I was worried
that the spreader plastic would melt.  With the homebrew feedline,
there is almost no perceptible temperature rise at 1500W, and the
performance of the antenna is noticeably better.

51 CW   83 SSB    134 QSOS X 40 Mults = 12,760 points  SO: High Power

Got on to give out some contacts, heard N6CQ/3 with a nice lead, and knowing
that Californian is Bill's native language, was sure I could make some
points and get a Tee shirt, without risking the curse of an alcoholic
beverage being shipped to my home.  I aimed for 100 QSOs, but then realized
that the 6 land guys will no doubt have N6AA and the other super computer
guys helping them check the logs.  Not knowing if they would use the 3 lost
QSOS per error, I decided that 134 should be enough raw QSOs to end up with
100 good ones and a shirt.  

K3WW PA QSO PARTY (probably the Biggest QSO party by a state that is not
also a Call Area)
242 CW  112 SSB   354 QSOS  94 Mults   50,854 points  SO High Power

Got on to practice voice operation with the CQWW comming up at the end of
the month.  Decided that since most of the activity was on 40 SSB, I didn't 
need all that much practice.  I find that with the antennas west, there are
a lot more nets and so forth on 20/40 SSB than when working DX.  It was
nice to find that the antennas still can be moved from Europe, but can now
forget that until SS.  

RE score reporting: first blush was to send them to KA9FOX for tabulation;
however, I also enjoy seeing what various guys have in mind when they
participate in the different contests.  It is also nice to learn new
excuses etc.

For some reason my direct reply to you bounced.  Sorry for having to post

Unless your wires are quite short (antenna operating way below resonance)
for 80 meters, I can't imagine why you wouldn't just feed it with coax and
be done with it.  You can support the coax any way you want.  At 80 meters
with SWRs below 10 or 15 to 1 or so the additional losses in the coax will
be negligible.  If you are running gross high power, make the balun a
ferrite bead stack type choke balun.  Amidon FT-87-75 cores on RG213 work
well.  At about 25 ohms per bead use enough to equal at least 3 times the
highest worst case feedpoint impedance.  Don't use less than 30 in any
case.  I have used as many as 70 when necessary.

Marko, OH6DO/AB6NJ (and now VR2NJ), asked me to post his "reservation" of
8R1K for WW SSB.  He is planning a serious Single Op/All Band effort. 
Hope he does better than last year--not only did Murphy pay a visit, but
he brought his whole family with him!  QSLs go to OH6DO CBA only.  Marko
says, "please don't use other addresses."

Subject: Sunday Sprint Summary
Message-ID: <3DVZTc1w165w at>

It's been at least a week since the last Sunday Sprint comment
appeared on the Reflector, so I will summarize the responses I
received.  These include several that were e-mailed directly to
me and several in response to a posting on the OH/WPA
The response was 2-1 in favor of Sunday Sprints.  The pro votes
included several that suggested holding half on Saturday and half
on Sunday. There was no correlation between time zones and the
votes of those responding.  Those preferring Saturday cited
family activities on Sunday more often than Monday morning work
problems as their reason for preferring Saturday.
I did ask my wife. She likes Sunday.
This sample may be too small and the time too short to move the
1995 sprints, or at least the February 1995 ones.  But there is 
certainly enough support for further inquiry, e.g. in the NCJ.
If further input mirrors the reflector comments, I suggest the
way to proceed is to have one sprint each month on Sunday
evening, for example SSB on Sunday in September and CW on Sunday
in February. If experience shows Sunday to be a major
improvement, the decision to make both Sunday (or to go back to
Saturday if they bomb on Sunday) can be made at a later time. 
Several comments were made about moving the sprints a hour
earlier in order to get better propagation.    A 2300-0300Z
Sunday evening Sprint in February sounds FB to me.  Just check
that the Super Bowl hasn't been moved back another week, creating
the mother of all contest conflicts. WN4KKN's point about 0330Z
September sunsets in W6 is noted, so the earlier time would make
sense for February only. 
The sprints may not be broke, but they can use some additional
activity. The comments show that there is a group out there that
could well supply that activity if the sprints were scheduled
more conveniently.  Let's give Sundays a trial.

Subject: Coax question
Message-ID: <Pine.3.89.9410102211.C24656-0100000 at>

Hello gang,

Esoteric station building question:

Does it matter if the coaxes up the tower are run on the inside or the 
outside of the tower?  I have always wondered if there has been any 
research on this subject.

I run mine inside, but only because it makes the tower a little easier to

ps - With CQ WW only 3 weeks away, construction on my new shack is still 
in progress!  I have plenty of antennas but no shack (until the building 
inspector clears out).  It may take FD style in the back yard, but I will 
be there for the BIG one!
