operations (non-
contest) by launching the DVPTSR. I have found that although my
Heil mic
will not even trip the VOX when plugged directly into the
microphone plug
of my IC-765, by using the DVP as a buffer stage, the mic works
very well
and I do not need to turn the gain up.
Perhaps this will be a quick & dirty solution for those of you
that have a
DVP.

In my case the Heil mic works great with the IC-765 (I have the
.47 mica cap in the mic line). But, when I use the DVP it is
definitely "hotter" in the audio department to the point that
there is some RF feedback. I guess it is always something!
I am amazed at all the variations we are seeing reported
considering these are production radios and microphones!

Until very recently, I have operated without the advantage of
having DX packet cluster access. I tried SOA (or whatever the
ARRL calls it) for the DX test. Did it help, not really, I was
going single band low power anyways. I would have found all the
stations regardless. So in my mind, there was no advantage.
But then again, I was not on a record chasing operation.
Keep SOA seperate from SO. I've tried both and prefer SO.

The various comments re Heil mic gain may reflect the differences in input
impedance of the various rigs...as I mentioned a while ago, the older Heil
HM-5's I am using work great into a 20K load, but go flat into a 1K load...
this may help explain the effect of using the DVP board as an input stage...
the difference with and without the impedance-matching unity-gain FET amp]
I put into the mic connectors is really dramatic with my TS-950's, as is
the change in tone (less highs into lower Z, sounds really alive into
higher Z)...I use a JFET, self-biased, with about 20K from gate to ground,
as a unity-gain source follower, powered by the voltage at the mic connector...
I also changed the circuit in my old DVK to have 20K input Z rather than
1K, with similar results...BTW, study the wiring of the DVP cables to see
how to do audio right without hum or RF: no signal conducted by the shields,
only by the internal twisted pair...73 de Dave, W6QHS

Message-ID: <09APR94.13293426.0203.MUSIC@CATCC>
Perhaps someone can enlighten me regarding using four COM ports to
service multiop CT, a MODEM, a mouse, and a TNC. The problem I
have had is NOT finding free IRQ's, but rather in getting any COMx
to function with any IRQ's other that the two "standard" ones for COM1
and COM2 (IRQ2 and 4 I think). Others have commented on the problems of
sharing IRQs. Jumpers allow me to change IRQ's such that each COM port
has its own unique IRQ; but, unless a port is given one of the 2 std
IRQ's, it won't work. "Checkit" software reports that there
is no IRQ for the port if I use any other IRQ but these "standard"
ones. I have called my computer store people, inquired of many,
and have gotten many different thoughts, but the most recent
advice was that I needed communications software that allowed me
to define both the COM port I wished to use AND the IRQ I wished
to use, otherwise only the standard IRQ's would be recognized--limiting
me to 2 COM ports. I have bought a mechanical switch that allows me to
select either the TNC or the Mouse, but every time I want to use the
computer at W3LPL for the contests, I have to open the computer, remove
the modem, and change jumpers to reactivate an external port with the
COMx and IRQ I was using for the modem. Any ideas??

I don't like the reasoning here.
1. First of all, there's the "old-fashioned" reason which goes back to the
original definition of single operator: no help with logging or finding
multipliers or contacts from any source.
2. Second, I don't agree that packet is not a significant advantage. For
example, every year I wonder how I could have missed so many of the
expeditions to the Carib. on one or more bands, even though I'm getting
better at using two radios. Such contacts would probably not have been
missed with packet and appropriate software to filter the spots. I have
little doubt that I would increase my score by at least 5% with packet.
3. I have the impression that some packet cluster networks are not "open"
during important contest weekends. Moreover, the practice of "private"
spots has become popular in areas where the open networks are maintained.
This means that THE ASSISTANCE RESOURCE IS NOT EQUAL between competitors
(not to mention regional differences in participation x propagation--spots
you can't hear or work). I'm not complaining here, just pointing out the
problems with making assisted/unassisted the same category.
Also:
>Given that the top single-ops are often beating (and certainly
>competitive) with the assisted guys, why do we need two categories?
1. Of course they are competitive. They are better at finding new ones than
95% of the people putting out spots. They also are likely to be doing more
with their station and their operating to take advantage of the so-called
single-multi style.
2. Are they really beating them to the top spot? A perusal of the results
for the last 6 major weekends leads me to believe that most of the reason
for the seeming lack of competitiveness of the SOA's is due to who's
operating and where from (station and geography).
3. Another factor in the seeming difference is the learning curve, which I
believe is still not level for most in the "serious SOA" group. And
computer software will only improve their use of the assistance.
John Dorr has pointed out several other very good reasons to leave it alone.
I hope the categories will remain separate.

The contest community, and amateur radio, has lost one of the greats again.
The passing of KH6IJ is very sad to me as I had the good fortune of knowing
Katashi and his family personally. His ability to explain something complex
simply earned him a position at Harvard. As a teen at our dinner table Nose
one day showed me-with a rubber band-what angle of trajectory would produce
the best results as far as distance travelled...I think my father was
trying to put the end of a dipole over a tree that day...occasionally there
would be a "Hint & Kink" in QST from KH6IJ-it was always one of the ones I
refer to as "a keeper".
When I became a ham, my first ARRL DX Competition contained only a few five
band QSOs, predominantly with DXpeditions to Central or South America...and
KH6IJ....a logcheckers nightmare, Katashi was never known for his
penmanship but boy he sure could run in a contest.
The past several years have been hard ones on our particular interest in
this many faceted hobby...now we see one whose operating was the standard
of comparison leaving us.
....one of the first jokes I remember hearing after I got interested in
contesting was that if you had a question about contesting you should ask
Katashi....Katashi Nose. Thanks for the wonderful memories - Aloha Nose.

Dave - I'm just curious - have you operated both SO and SOA under
similar station condx?
My "analysis" of the scores show that, as a rule, the true single ops
really out-QSO the SOAs, so catching every multiplier isn't as important.
For a limited operation (hours, station, etc.) I agree that packet is
usually an advantage. But when operating full-tilt, I think packet is a
major distraction (credit to K3WW for coining the catagory "single-op
distracted"). I find it really screws up the rhythm, and makes you think
twice risking losing a run to chase a mult., especially during the
first 24 hours.
Also, here in megacluster land, when a new/good mult appears on packet,
it is usually counterproductive to jump right in because the N3RS,
N2RM, W3LPL type stations (not to mention the 50 or so other
KW/tribander/monobander @75+ ft stns) create so much noise and delay...
Of course, it would be real tough to truly quantify advantage vs.
disadvantage of packet from same station from year to year cuz of
band condx changes.
I am for combining the catagories. I think that would really give
all contenders incentive to figure out whether packet really helps or
not.

Subject: IC736 lands in USA
Message-ID: <9403097659.AA765947225@atlas.ccmail.airtouch.com>
Just got back from the local Ham Radio Outlet, and was playing with the new
Icom 736. I had no idea that it was due to arrive so soon, for there have not
been any adds in the radio magazines. If you recall, this radio was of great
interest some months ago when I was looking for a new contest expedition radio.
I almost walked past the radio, but the $1879 price tag didnt make sense. The
736 looks almost exactly like the 737, though a tad larger. I had the bonus
of having both the 736 and 737 next to each other, so I could see how the two
functioned differently.
The front panel looks the same, but on closer inspection, there were a few
differnces. In reviewing the notes from Sandy WA6BXH, it seems that not all
the advertised features in Japan apply to the USA version. Most notably
missing was the internally switchable 110/220v power supply (you can buy one
voltage OR the other), and only one key jack.
The following features I did notice:
- 160 thru 10 (100w); and 100w on 6 meters
- When operating split, you now have both VFOs displayed
- Clearable RIT (just hold the RIT button in and wait for beep)
- Multi function meter; SWR, ALC, PWR out (strange, but when selecting the
various functions, they are displayed in place of the main VFO readout,
thus blanking out the freq display. I hope this doesnt affect your signal
if you just happened to be transmitting)
- Internal power supply; either a 110v OR 220v model (no 12v feed option)
- Built in antenna tuner. Unit will remember antenna choice and SWR settings
per band
- 2.1 kHz SSB filters, up to 2 optional CW filters (no optional SSB filter)
- double band stacking regesters per VFO
- XFC - monitors your transmit freq when operating split
- built in keyer
- 1 key jack (from what I remember)
- No independant RF input jack (ex: external beverage RX antenna)
- A/B antenna switch up front
- Built in VOX (unlike earlier 737s)
- 21 lbs
There were a number of programable configuration options, but I didnt play with
those. The tuning speed was a bit fast for me, but that may be one of those
programable options. Though the radio fell short with some expectations, the
736 is certainly was a huge improvement from the operating effeciency and
features of 737, and definately seems to fit my expeditioning needs better than
most other radios on the market today. Now it's time to negotiate on price.

Personnaly, I feel that packet assisted operating should be allowed
and even encouraged, but should be considered for what it is, part of
the Multi Op class. After all, the assistance is real-time and comes
from other licensed operators not from a bunch of SWL's or other
interested third parties.
BTW, I have packet, we have a good network here in the Northwest but I
don't use it for contesting. I choose to compete as a Single-Op and
don't need (or want) real-time help from other operators - thank you.
If I wanted to compete that way I'd enter Multi-Op.
