yeah, but Gary, the Dayton guys always seemed to have trouble getting
organized on mass transit. maybe they should 'qsy' to some place that can
handle large crowds routinely -- say Orlando....not that the OARC would
approve...8)
of course, maybe we should just get everyone organized to park at the mall --
"economic turmoil reigns! Salem Mall closed by invading hordes of radio
hams...McDonalds makes emergency deliveries to restaurant after the entire
food supplies were consumed by the horde..Noble Romans reported improved sales
reached 'sluggish' levels over the weekend..residents report lamps glowing
with power turned off, wavy lines on their TVs and strange thumping out of
stereo and radio speakers..young children frightened..strange vehicles roaming
the streets -- could they be operators of cat detector vans? are your cat
licenses up to date? is it the end of the world? is Elvis there?"
maybe the hamfest should be at the mall...any old NCR warehouses unused? and
has anyone found a use for the old Western Electric plant in Indianapolis?
That place even has a very large parking lot AND a huge amount of space under
cover and an International Airport that's on an Interstate and easy to get in
and out of (unless Dayton's changed a bunch..)
maybe dayton needs another big event around september/october so having a
large parking area at the Hara Arena would be more practical -- maybe the
arena could be leased out to the Tonya Harding Physical Therapy Center for
Injured Skaters.
Dayton may have had the "natural" for a large convention and has certainly
worked to get this spot as the "big one", but maybe it's ripe for plucking
given the constraints forced upon them by the area.

Probably depends on where in the pattern you are, can't think of any
inherent reason for a quarter wave ground plane to have more gain than a
vertical dipole. If I understand what is meant by a quarter wave ground
plane its a 1/2 wavelength antenna but the bottom leg(s) are not in the same

Subject: Kenwood TS940 pll-car unlock....HELP!
To: info-hams@ucsd.edu
My TS940 (1987 vintage) unlocks during warmup, receive (or xmit) goes away
and a half second later the display goes to all dots. This lasts for a blink
to a few seconds each time, and happens zero to a half dozen times only during
warmup from cold which takes 5 or so minutes.
I have done the following:
1. Inspected the PLL, CAR, and DIG A board for solder breaks...nothing obvious.
2. Flexed (lightly), cooled, and resoldered many connections on these boards.
3. Inspected the VR board and resoldered this and that.
4. Observed no power supply voltage changes during the unlock on these boards.
5. Observed the unlock signal occuring during the problem, but was unable to
tell which pll chip was sending it first.
During all of this extreme invasion of the 940's guts, the characteristics of
the unlocking during warmup has not changed one bit. Makes me think I'm on the
wrong boards.
I've also checked all the peaking up, and setting of vco ranges on the pll and
car boards according to many suggestions and bulletins. R100 on the pll board
was not the problem, as once reported here on the net.
Is there any particular coil that has been troublesome, or some other part
perhaps that anyone knows about?
The problem goes away during the summer months.
Help.

Sure. There were some synthesizer spurs that were fixed with
judicious grounding. The VHF receiver sensitivity wasn't fabulous
(approx .40uv/12db SINAD). The transmitter would oscillate badly
when mistuned. Two kits arrived dead and left working. I'm
not going to claim that they were fabulous performers. Nor were
they stable over a wide range of temperature or power supply voltages.
However, they do operate. I didn't see anything "illegal"
or dangerous in the operation or design. Again, I do NOT
consider the radio a superior or state of the art product.
If it had a dual gate GAsFET front end, high level mixer,
helical resonators thruout, dual PLL tx/rx local oscillators
for fast TR switching, fewer tx spurs, tracking filter rx
front end, built in PL, RS-232 control, ad nausium..., I would
consider it state of the art. Is there some other kit manufacturer
other than Ramsey that has a superior product?

I've received 4 pieces of email indicating that this would be
a good thing to do. All it would take is making friends with
your friendly local 2way shop. I've noticed a trend over the
last 25 years. The hams and the commercial operators appear
to barely tolerate each other. 25 years ago, every two way tech
was a ham. Now days, the techs with ham licences ask me not
to mention that they work for a commercial shop. One local ham
needed a commercial radio programmed for ham frequencies. This
proved to be a major political challenge.
My pilgrimage to the local repeater site (5 minutes from my office)
is not much of a challenge. I do it whenever I find the excuse.
However, 50 check-ins followed by 20 arguements does not encourge
repetition. What I ask is that they check in normally. If the
deviation is low, I ask them to YELL into the microphone. This
shows if the deviation setting is low or if the tx audio gain is
low. I have to explain the difference between the audio/mic gain
and deviation at least 10 times. The process has lasted as long
as 3 hours. Many hams will check in with every radio they own
causing me to get confused. The same hams check in with the
same screwed up radios every time. Little wonder the commercial
shops don't want to spend the time and effort.
At the last Winterfest in Montery CA, the KM6DZ group used the
latest greatest HP service monitor to check handhelds and mobiles
for anyone interested. Most everything was measured. Next year,
the box will probably be HPIB (IEEE488) computer controlled so that
it can be done automatically. Many of the brand new radios were
miserably adjusted. In spite of the large number of handhelds
in evidence, only about 50 radios were checked. It makes me wonder
if the others even cared.
It's not too difficult to turn your repeater receiver into a piece
of test equipment. Here's some ideas:
1. Instant replay. Install a speech recorder that records the last
10 seconds of a transmission. If someone wants a signal report, they
can hear themselves and judge for themselves.
2. You can measure SINAD remotely. Modulate the rx local oscillator
of the repeater to +/- 3.0Khz deviation at 1.0Khz. Notch out the
1.0 Khz tone at the repeater audio with a commutating synchronous
filter. The ratio of the audio before and after the filter is
proportional to the SINAD. If you want to go high tech DSP, read
the June 1993 issue of QEX for a program to do it with a TI320C25
DSP chip.
3. Measure frequency remotely. Many repeater controllers (RLC-1)
have A/D converters suitable for measuring the discriminator
voltage. Some have remote offset calibration functions for dealing
with adjustments and drift. Have the repeater belch the frequency
error.
4. There are still a bunch of tunable PL encoders in use. Our
repeater K6BJ returns a differnet courtesy tone depending upon
whether the PL decoder hears the correct tone. Just tune till
the tone changes.
You don't need a service monitor to get things right. It helps,
it's nice, but it's not necessary. Your repeater can do the job
adequately with some construction. If it works, turn it into a
kit and sell it.

20 or 30 years ago, when military surplus was plentiful, there were lots
of articles in the ham rags about how to convert military gear for ham use.
There were also many articles on how to modify commercial amateur
gear: "Add a Product Detector to a 75A2 Receiver" "A Q-Multiplier for
the HQ-110" "Convert Your Command Set Into an SSB Exciter" etc. Not many
amateurs built complete stations from scratch even then, but most did at
least some surplus conversion or modifications to commercial gear.
I agree with you that QST should do at least occasional articles of that
genre. Some years ago, QST virtually banned tube-based construction
articles (other than high-power RF amplifiers), and I suppose that's
all to the good. But there's a lot of older tube-type gear out there
that sells for a song. With a little modification, those old clunkers
could have a lot of life left in them.
For example, how about a digital readout that could be configured to
work with most any transceiver/transmitter/receiver? (With modification
instructions for several of the most-popular older rigs?) How about
a synthesized external VFO? If it covered the 5 - 5.5 MHz (or so) range
it would work with many older radios. I wish I had the time to work on
some of those projects! Anybody else have more ambition than I?

The key for me in working 40 CW successfully (and I'm not all that
successful!!) is having a good receiver and listening carefully
and diligently. Band conditions seem to vary quickly and drastically
on 40; you should be able to recognize when it is a good time to work
hard for DX and when you just might as well rag chew with the guy
down the street. I wouldn't (and don't) use any antenna that was
"worse" then a resonant dipole in performance. You might consider
some of the "shortened" dipoles if space is a factor; but I don't
have any experience with them.
BTW, I use 100W; I'm not bored enough to try QRP yet..... I believe
that most successful QRP operators have spent lots of time working
with "normal" rigs before they go to QRP. At least that's the
impression that I have.

If you are really interested in the relative gains, etc, of various
lengths of vertical radiators, you can get a copy of the FCC
rules and regs for AM broadcast stations. This used to be available
for a very small sum from the government printing office. In it
is a chart showing the field strengths developed by various lengths
of vertical radiators. You will see that a quarter wave vertical
does *not* have more gain than a half wave, actually less. The signal
strength continues to increase as the length of the radiator is
increased and tops out at 5/8 wavelength..hence the popularity of
the 5/8 for 2 meter mobile work.
Also at work here is the fact that a 1/2 wave radiator has a
very high driving impedance. Consider the antenna and
ground to be in series, like two resistors. If the
ground connection is high impedance,like when you have
no radials, then, if the antenna is low impedance (1/4 wave),
most of the energy is dissapated in the ground connection..
not at all what you want. However, if the antenna is
high impedance (1/2/wave), then a much larger part of the
RF is consumed in the antenna, which is what you want.
It's still probably a good idea to ground even a half wave
vertical. It won't hurt and probably will help. Otherwise
you're depending on the capacitance of the coax feedline
to act as a ground and then there's the lightning thing...
One note concerning ground plane antennas. They don't work
as "ground plane" antennas until they are sufficiently high
that the RF field from the antenna flows more in the ground
plane wires than in dirt. If it is too low, you get severe
losses from a quarter wave ground plane. This can be overcome
by increasing the number of ground radials. THe FCC used to
require 120 radials to achieve proper efficency when the vertical
was right on the ground. When it's higher, then you need fewer.
Since the half wave antenna has mostly voltage at the bottom
and not current (high impedance), then the RF field is highest
at the middle of the antenna and does not flow in the ground
so much..ergo, the efficiency is higher when ground mounted..unless
you want to put 120 radials on the 1/4 wave!
Hope this helps..
Jim, W2XO
