[Elecraft] K3 interface to THP 1.5Kfx amp

[AD6XY]

Thanks for this info, I have a 50W THP amplifier and found the DIN didn't fit
properly. Now I know why.

I have an HL1.2kfx which came with a plug which I have wired up for PTT.
This amplifier produces 600W rather than 750W and is a good match to the K3
for those countries with 400W limits and without the +-3dB measurement
tolerance applicable in Germany, where they have a terrible problem
calibrating their power meters.

The 1.2kfx does not come with automatic band switching yet internally it is
almost exactly the same as the 1.5kfx and uses relays for band select
controlled by a rotary switch. The RF decks are the same but the PSU is
lighter duty which is why the power rating is lower. Once the warranty runs
out I will enable automatic band selection via a logic board.
