Subject: 150 watt 70cm Linear Amplifier?
Does anyone know of a supplier for a 70cm/440 Mhz linear amp in
the 150-200 watt range that can be driven with 20-30 watts?
Most suppliers carry Mirage and RF Concepts amps, but only up
to 100 watts output.
Please E-mail direct to: sem2r@galen.med.virginia.edu

Subject: Best HT? Alinco vs Kenwood vs ICOM vs Yaesu?
Add to the Yaesu FT-11 features:
Alphanumeric labeling of memories and does messaging (might or might
not be important to you).
1.5 watts max power with 4.8V battery, 4W with 7.2V battery, 5W
with 9.6V battery. With the small battery it's slightly smaller
than the TH22 but has 1.5W vs 3W for the 22. The power difference
would generally not be significant, but could be...
Lighted keypad, excellent display lighting.
Receives airband out of box, but mine has atrocious (unusable)
sensitivity in that range. Might be a problem with mine or a problem
with a particular rev. I haven't pursued it.
Up and down buttons for volume and (shifted) for squelch, no knobs for
these functions.
Needs an adapter, which also contains a fan, for use in your car
(with 12 volts). The fan is probably an excellent idea, but the
adapter is probably expensive. There is no power plug-in on top.

The JSC Amateur Radio Club, W5RRR, has both, as well as an IC-781. (Thanks,
Yaesu, Icom, and Kenwood, for the donations!) Of the two, to me there's no
comparison: the FT-1000 is easier to operate, much less confusing, and
(important to me, but maybe not to you) much more pleasant to operate full
break-in CW. The Kenwood has an annoying thump on every keydown in the
receiver in CW mode.
If I were buying, it'd be the Yaesu.

Subject: Icom IC-M120 Marine VHF Radio
There are two connectors on the rear panel of this radio. Need the
pinout of each connector. One is power and remote TX key and I think
some other functions. The other may be a remote connector as well.
There seems to be a board missing from the bottom half of the
chassis. Also need to know what that is. Is it some sort of
uninstalled option or actually missing?
A post here or e-mail appreciated.

After reading your post I thought I'd check out my 470. Well,
after some quick tests, I got 4 W at VHF and 3.7 at UHF. I thought this seemed
low, so I checked the SWR while the old coax switch was inline. It was
showing 1.65 on UHF. After pulling this, and the SWR down to below 1.1:1, the
numbers are 4.8W on VHF and 4.5 on UHF.
This is on a 13.0 V supply into a 50ohm load thru a Yaesu YS500 V/UHF meter.
I'm using "Cable experts 9913 equiv" cable, PL259 type conns.
Well, so much for that switch...
