High Power ATU's suitable for the new AMP~

Gents,

I have used this SGC-235 500 watt capacity automatic ATU for more than 5
years. It is fed by a small Icom and the SGC cube amp in the back of my
Landcruiser. I run an ex military whip of about 12 feet, also the normal 102
inch whip. I have used this ATU to feed dipoles on poles, to feed 40 foot
verticals and also long wires. It has done everything always without a
complaint.

If you demand Elecraft re-invent the wheel than perhaps they will. However
it is certainly not necessary for them to do so. This ATU is all you need no
matter what you want to feed and it will handle the new amp.

I will prove that as soon as my new amp arrives. But keep in mind those of
you with little experience, 500 watts out of 1 amp is no different than 500
watts out of another. You can also control the SG235 remotely by sending 12
volts up the coax to it and they have the small little isolaters to help
with that.

Have a look and lets put this thread to rest. 73, N2WL Bill

In reply to this post by Bill Levy

I've used a friend's SGC-230 in a mobile installation and been quite
impressed with it. However, I'm not so impressed by the specs of the
SGC-235. If I read them right, it's good for 500 watts only on SSB, for
other modes it is only good for 200 watts and it does not cover 6m at
all. I want to be able to run things like CW and RTTY at more than 200
watts (especially helpful for RTTY) so the SGC-235 just does not cut it.
I assume the upcoming KAT-500 will not have such limitations.

It doesn't.

1.8 to 30 MHz.

High Power ATU's suitable for the new AMP~

Bob,

You are correct. I do need some power for 6m DX. I am now struggling to decide
between KPA500+KAT500 and SPE Expert 1Ka.

For variety of reasons in my operation, I need an ATU.
TNX & 73,

Johnny VR2XMC

Administrator

KAT500 will handle 500w at large SWRs up through 6M. It looks likely it
will even handle 3:1 at 1500W.

It also will seamlessly integrate with the K3 and KPA500, plus work with
other rigs.

Stay tuned!

73, Eric
