To: ham-equip@ucsd.edu
I am considering the purchase of an Alinco DR130
50W 2-meter mobile rig. It's one of the most
inexpensive 2-meter rigs around.
Any comments on it are appreciated. Thanks.

To: ham-equip@ucsd.edu
Pet hate time.
Best just leave your faulty switch and modify the ten-tec power
supply.
Disconnect the high voltage wires to the rig, and link the
power supply so that the switch in the rig is totally out of circuit.
Use the switch on the power supply to switch the whole system on and
off.
This loses a conveniently located switch, but gets rid of all
dangerous voltages in the corsair itself. It also takes dangerous
voltages off of the middle two conductors of the big ribbon cable from
PSU to radio.
This ribbon cable has only single layer insulation, and in Britain at
least is illegal at power line voltage.
A friend was repairing a corsair and got a shock at 240v, he never
expected full line voltage inside a 13.8v rig powered from an external
supply.
I do not know whether the system complies with US electrical safety
standards, but the single pole mains switch and the lack of warnings of
dangerous voltages inside breach ours.
This is a great radio. The two areas I've modified on several radios
involve line voltage/safety and filtering the various phono connectors
on the rear panel. These are often routes for RF pickup and can latch
the unit in TX if there is RF in the shack.
Sorry, I have flaky email, but posting works reliably.
Cheers

Hi all. I just wanted you all to know that 2 of my radios were stolen. If you
see them, give me a call at (614)341-0050. This is my pager; just enter your
number at the prompt (with area code, please). Here is what was stolen:
Icom 24AT S/N 12176
Icom 2AT S/N 91971
Polaris Speaker/Mic, White WITH ADDED SWITCH ON BACK (small,red/grey slide)
A lot of other stuff went with this stuff, but none of it is IDable. (Would you
believe they got my jump kit, stethoscope, and a lot of other non-marketable
stuff?) Geez...
Thanks folks.

To: ham-equip@ucsd.edu
I have been asked by someone without access to internet to post this.
A recently acquired 2 mtr all mode Icom 290A does not have an internal
back up memory circuit. Unfortunately we also do not have a schemetic.
Has anyone installed memory backup ? Apparantly it was always meant to
have a live 13.8 v line connected. Or can anyone provide the memory
voltage and the ic pin number where this should be provided (with
appropriate diodes, of course).
Please reply to me : dara@physics.att.com

My thanks to the many who replied to my question about Drake R4A's ... I
received more responses than I can reply to at present, except in this
way of saying thanks to all of them.
Unfortunately, by the time I received and pondered all the advise, the
radio had been sold. C'est la vie.

Classic battle? Gee, these don't seem like similar radios at all to me.
One is single band, ham-band only, 50 watts out, low-power drain; the other
is all-band, general coverage rcvr, 100 watts out, standard power drain.
One costs less than $500; the other is over $700, isn't it?

Actually, these radios ARE comparable, in a sense. A USED 747GX can go for
around $550-600, which is about the price of a Scout with 80, 40, 30, 20,
17, 15, 12, and 10 meter modules ($495 + 7 * $20/EXTRA BAND = $635). Add
the keyer (although it may be included in the Scout), and the rigs go
for pretty comparable prices.
So then the dilemma is the following:
The Scout almost surely has a better receiver, and better filtering.
The Scout ALSO makes you worry about what to do with the extra modules
when not in use. Think about cassette tapes in your car...
The Scout, from all accounts, does NOT use such little power, compared
to the Argonaut and other QRP rigs of old. BIG LED display makes
sure of this.
The Yaesu has a general coverage receiver.
The Yaesu covers all ham bands right out of the box.
The Yaesu lacks the excellent receiver & filtering.
The Yaesu is bigger.
They're built to an entirely different philosophy. Depends what's important
to the owner. Ten-Tec also has excellent service if you need it.
But they ARE, undoubtedly, in the same price class, and must thus compete.

If I had them both in front of me each with a 550 price tag, I'd take the
Yeasu FT-747. Like what has been said earlier, the Scout has better filtering
and a better front end, the 747 gives you the option to remote mount the
RF box and keep the head up front. The 747 also is all mode, so you can
work 10 FM mobile....can't do that on the scout. You can change bands at
any time, and have out of band capability (if you're in MARS, CAP, or a CBer
hi hi hi)....
My question to the group is: Can the scout go out of band? Is it possible
to modify the 4mhz and 7mhz modules so that I can get a 4.0-5.0 spread out
of it....and a 7.0-7.5 or something.... I'm in both Air Force MARS and in
Civil Air Patrol, and I'd like to have HF mobile, but I want to 'go all the
way!' The Scout seems like a great rig for the money if I can get the out
of band mods on it... (could care less on any other other bands, just 4 and
7! )
