Well,
Myself and my chum Vince, G0ORC headed off to the National Hamfest last Friday, following a lot of consideration I was thinking of changing the Linear Amplifier that I have here for HF work. I have been using a Ameritron 600 watt Mosfet linear, with great success, however I was wanting to be able to run UK legal limit RTTY without pushing things to far.
ML&S had a very intersting linear amplifier at the show which just took my fancy, another great re-shuffle in the shack and it's in:
The linear is manufactured by a company called ALPIN:

And contains a single 4CX800A tube capable of 1300W SSB and 1000W continuous CW or RTTY work. The amplifier looks (both inside and out) to be a close copy of the ACOM 1000:

I am told that Alpin are ex-employees of ACOM or something like that (I don't actually believe a word of this).
Anyhow, the amp certainly looks the business:
and it's very easy to tune, I have created a chart of the "starter" settings for my setup and you simply rotate the "load" control as instructed on the LCD display and then peak the "tune" control for maximum smoke (RF out).
There is a good review of the amplifier here from RadCom:

The review seemed to say the right kind of things....
I've had a dabble in the CQ WW RTTY contest this weekend and have been delighted with my station performance. This is a map output from my log from this weekend, most of the contacts have been on 10M:
you can see that I have worked far and wide and the RTTY station here at G0MGX is clearly working well!
Cat's not been helping much as normal:
Good though, egh?
