I have a DJ-160, it is the 2 meter version. What info
exactly do you need.....(the manual is too big to type
it all in here :-) ).

Hello Dobbs,
Guess we missed each other on Fri. I was listening most of the day, but
spent some time going to the new BJ's in So.Attleboro. You've gotta get
there... talk about cheap food.
Anyway, yes, I contacted everybody about the power supplies. Nothing
yet, but at least I am a lot more familiar with that SLMR program now
and how to get around it.
Cleaned the gutters on the garage today and also filled up 5 bags with
leaves and it still looks like we haven't raked.
So, what's up on your end? Are you still looking for another apt?
If you've got a chance, give me a call on .985 tonight after 7:00.
73, Dennis

To: ham-equip@ucsd.edu
I am intrested in tearing apart a Icom 80 series battery pack to make
a sturdy way to connect my 2SAT into my car. Because I would like to
keep this small and inexpensive I decided I would check the net for
people who might have an old (or unused) BP-81 or BP-82 that they
would be willing to sell for $10 or so before using a new or working
pack.
I would also consider trading my working BP-82 for a dead pack.
Please Email if you are intrested.

There is a thing called 'physics' that limits the ability of the radio
to lock on frequency and rx/tx too far out of band. The mods available
for the microprocessor extend the capability of the radio to tune to a
larger band spread than this physical limitation. You're not missing a
thing. And, this paragraph text seems to have become justified, Neato!

You are confusing the General Mobile Radio Service (GMRS) and
the Business Radio Service. GMRS is UHF only and does require
a license <period>. Radio Shack (and others) sell low cost GMRS
transceivers. They also sell VHF radios set up on the "itinerant"
business band frequencies (151.625, ...). These radios also
require a license. Business band can also include UHF, but these
radios don't seem to be quite so prevalent, at least not at Rad Shack.
Give a listen on 151.625 and you will hear all kinds of communications,
mostly unidentified and (I presume) unlicensed.
IMHO Radio Shack should be sure to inform the user that a license
is required. (I believe that the license form is generally included
with the radio, but....). RS, of course, can't guarantee that the
radio is used properly.
These same type of radios (GMRS and itinerant Business band) are
showing up in all kinds of catalogs from outdoor products companies to
computer equipment suppliers ("handheld communications for use when
setting up cabling for LANs"). Most of these companies are doing a
poor job of communicating the license requirements. :-(

For abuse, I think you can't beat (ahem) Motorola public-safety gear.
Particularly the older units are really tough. I've seen them dropped,
crushed, immersed, and everything else, and their the "Timex" of HTs.
If you can find a surplus unit and pull it into 2-Meters (narrow band,
of course), you couldn't do much better.
As things have gotten smaller, they've gotten more delicate, naturally.
Check, also, with a commercial radio shop in your area. It might be
expensive, but they probably can order/program you a ham-band version
of a ruggedized HT.

Hi,
A friend of mine looks for software to control a kenwood TS450S with
a computer. I looked at an internet ftp site but have not been able
to find such software.
could somebody tell me if this exist and where i could ftp it ?
Please, reply by mail to lvds@stdin.gatelink.fr.net
Thanks.

OK... I looked up an old message which summarized QST lab test results for a
number of receivers, and the FT-747GX had the following test results:
MDS: -136dBm
IMD Dynamic Range: 90dB
Blocking Dynamic Range: 109.5dB
Third Order Intercept: -1dBm
The Ten-Tec spec for Dynamic Range looks like a blocking dynamic range
spec, and is 5dB poorer. The third order intercept is very similar.
As the specs indicate, the 747 is somewhat more sensitive.
I've always been rather impressed with the performance of the 747 front
end, considering it is an econo-box with many features. The 747 front
end consists of an elliptic 5th order (or 7?) low pass filter with a
corner frequency of 30Mhz and a zero (null) located directly on the 47Mhz
first IF. Then there is a deck of diode-switched elliptic band-pass filters,
again about 5th order, then an active JFET singly-balanced mixer. The mixer
feeds a 47Mhz crystal filter... Not a bad design at all...
I'd be interested in seeing the ARRL test specs for the 555, since this
comparison here is between published specs and lab test results. If Ten-Tec
is conservative, then maybe the Scout 555 will look better in the lab. If the
Ten-Tec specs are optimistic, then the advantage will be even stronger for
Yaesu.
