1. In response to Mike Sattler's and Gary Coffman's
comments concerning military radios and their whip antennas,
let me clarify a few points from an Army perspective.
2. Our major family of radios for our tactical units
operates in the 30.0 to 75.95 MHZ range, in the FM mode, and
in two power ranges: high @ 35 watts; and low @ 4 watts.
3. From a tank (either Abrams or the older M60 series) I
can usually talk reliably 20 to 30 miles on high power on
"good" (relatively flat) terrain. Low power is usually good
for about 5 miles. In the hilly terrain of the Fulda Gap in
Germany, these ranges are reduced significantly, but usually
suffice for normal tactical unit communication needs.
4. Hope this helps.

Paul,
We have installation guidelines for several manufacturers (GM, Toyota,
Nissan, Volkswagen, Mercedes), but nothing for Ford. John Ochs, Ford Public
Affairs, 3000 Schaeffer Rd, Dearborn, MI 48121, told us in a letter
that dealers have access to "Technical Service Bulletins" that should
help, although he did not tell us what they were or what is in them.
All in all, Ford had a fairly good response to our inquiries, but, like
ALL of the manufacturers, they said that if any aftermarket component
causes damage to their car, it will not be covered under warrantee.
I am compiling files by manufacturer, so I will send the Ford file to
your address in our membership records. I will also include the best of the
installation guidelines -- GM's. Our book, Radio Frequency Interference --
How to Find It and Fix It, also has a reprint of the GM guidelines in
the automotive EMI chapter. (Anyone wanting a copy of the GM installation
guidelines and one of the auto files, please send me a large -- 9X12 --
SASE with 98 cents postage -- I will send it right out.)
And, as always, I am looking for any and all reports on problems or
solutions to auto (or any type) of EMI problem.

Not an uncommon problem! I have found that even GM has this sort
of problem where the front-line troops are not aware of EMC policy
or procedures.

Ford has put out a service bulletin on the RF hash generated by
their fuel pumps. (Tech Bulletin 92-6-9)

Subject: Mods for the AEA/ARE "HamLink"
To: info-hams@ucsd.edu
Mods for the ARE/AEA HamLink:
1. If you are using an ARE ARE-60, chances are you have an old version
of the firmware. The latest version is Ver. 4.0 - (2 EPROMS) Call
AEA (Hadley Allhands) for more info on how to obtain the new firmware.
2. Change R14 from 130K to 248K if you have Touch Tone falsing problems.
The tone detection was much too fast and would cause HamLink to false.
In the middle of a QSO, often the radio would QSY some where else. The
248K resistor solved this problem. Hamlink still decodes tone very fast
(setting #6 or slower on the Alinco DJ-580) Careful when changing this
resistor as the foil near the 8870 IC comes up from the board very easily.
3. Older units used a 13K resistor at R10 to determine confirmation beep level.
It was much too loud so they put in a 100K resistor in all their newer
units. This was still too loud for me so I replaced it with a 1M 10 turn
pot. This allows me to adjust the level to my taste.
4. If you are using HamLink with a Yaesu FT-1000 or FT-990 you might have
problems getting the unit to communicate with the radio. ( Via the CAT
port). If this is the case, place a 2.7K resistor between pins 1 and 2
on the CAT DIN connector (serial date + ground).
5. I moved the internal programming jumper to a toggle switch on the back
panel. Same for the reset switch. (Drilled 2 holes on back panel).
Brought out an extension plug from the internal RJ-11 jack with a double
female connector. With this arrangement, I don't have to open the HamLink
every time I want to program the unit.
6. Bug that remains; #71# - pin 9 on the D25 connector should go high for
100 mS after the command is received and does not. All other ON-OFF
functions work fine. AEA was made aware of the problem in June, perhaps
there has been a fix since.

Subject: Neat Feature on New Motorola Commercial Handheld
To: info-hams@ucsd.edu
Here's a neat feature of the new Motorola Visar handheld, that I hope will
show up on some future hamband talkies. The Visar is a tiny 5-watt
16-channel handheld, designed for police and similar applications. It is
available in VHF, UHF and 800-MHz-trunked models. Cost is $1,095 each. (At
least that is what I recall the salesman saying.)
The Visar has an LCD channel display mounted on top at a 45-degree angle,
so it is visible from above (if the radio is in your shirt pocket) or from
the front (if you have it in your hand). Of course, that means that the
display must be upside down from one or the other position.
The neat feature is an invert button. Press it and the characters in the
display electronically invert! No need to read upside-down numbers!
Hooray for Yankee ingenuity!

[ accounts of signel level problems deleted ]
Hi,
I also had the same problem with my Yaesu FT747 and my $12 (hamfest)
Kantronics UTU. The drive level from the UTU audio output was way too high
for a mic level input. I used a resistive divider in the output of the UTU
(right in the mic connector shell). I think it was 10K and 600 ohms to
ground from the UTU audio output. (10 K on the UTU side, 600 to mic gnd).
The mic line to the Yaesu comes off of the tap between the two. Works like a
charm. The mic level pot on the rig now sets the proper output level when it's
at about 12 o'clock. Looks like this:
aud. from utu --------+
|
>
R1 < 10K
<
+---------- Mic to rig
>
R2 < 600 ohms
>
|
sig gnd from utu ------+---------- Sig gnd to rig
Oh and yes, FSK is better, if you have it.
Adjust the value of R1 so that your transmitter output level and mic gain
pot track about the same as it does in SSB. If your using with FM, use a
deviation meter.
If your interested in the exact values, email me and I'll check out the rig
at home tonight.
Hope this helps,

I have a chance to buy a Swan 350 in "excellent" condition. I know nothing
about this rig other than that it puts out 300 W and is probably old.
Anyone have one or know how they do? Are they tube or solid state, analog
frequency display, modes, bands covered, general coverage receiver, built
in filters, suitable for HF packet? Also, what would be a good price? The
owner is asking $325, including speaker and power supply. Please feel free

Of course they are related. Listen to them dancing around -
clickety-clack, clickety-clack, ting ting ting from the bells
and stuff. It sounds just like that big contest station a
bit further up the band. The rhythm is the same. And why else
do people talk about radios with all the bells and whistles?
And Alfred Vail (who worked with Samuel "Fine Business" Morse)
died in Morris County.
Coincidences? - of course not!

bad enough having boys dressed up as girls - say no more, squire!)

I have been using a TS430 as a mobile rig since they came out.
: How sensitive is the final to SWR?
Like any solid-state final, it will decrease it's power if the swr is
high. In a mobile operation, the principal swr culprit is a mismatch
of the antenna impedance. So, I use a small MFJ tuner. Not to
compensate for a non-resonant antenna but more to compensate for the
mismatch.

Dont leave home without it.
: Does the 430 need an external speaker?
Depends where you mount the 430. I am practically deaf in my right
ear so I put a speaker on the floor to the left of the drivers seat.
: How useful is the mobile mounting bracket?
It is always better if you can mount your mobile radio. The 430's mounting
bracket is just fine. In my suburban, I use a mount but in my Cherokee
I just put the radio in the right seat.

I had a VW camper once and mounted the radio on the right side of the

There have been a number of dicussions about mobile antennas in
rec.amateur.radio.antennas, it would be good if you could go back and
look at some of the postings.
Some people like 75 meters, I go with 40 and 20 meter CW. 17 meters is
a very good mobile band when it is open.

I have a 5 watt HT with a 4 element quad antenna (in the attic) pointed
at Pikes Peak (it makes a great reflector of anything overhead). I was
able to send packets to MIR as they were confirmed by a "busy" packet
coming back. I have also made one successful connect to MIR on Oct 13.
I've tried the shuttle on the STS-58 mission, but had no success with
them on voice or packet. I could hear them, but they apparently couldn't
hear me. I've heard OSCAR, but don't have a radio capable of transmitting
on 435.016 MHz. (Also a 5 KHz freq step on my HT is a little "rough"
when compensating for Doppler shift.)
So with an HT and a good antenna, MIR is doable, the Shuttle is a little
harder, and OSCAR would probably require more hardware/power/antenna.
But that's what experimenting is for.

After looking thru a motorola catalog we had at work, I'll tell oyu what I know about Police Digital comms...
It seems that most of the MDT's in the cop cars are running 4800 bbps or 9600 bps with some kind of sceme called MDC if that helps you. I do konw that it is not the regular old AX-25 that they use...although some agencies, ie: PC Beacn FL polic,e looked like they were using little Henry TNC's with radio schalk laptops....so you never know...sdepends on the agency.
I hope that helps.

Ken and all, a 60W 2M amp and a decent yagi would work fine. I WAS
only talking about AO-21, the flying repeater, to access it, you
transmit on 435 MHz and listen on 2 meters. Obviously you need a UHF
