[Elecraft] [K3] Tokyo Hy-Power HL-1.2KFX amp interfacing (to ALC or not to ALC?)

[Alan Geller]

I have a THP HL-1.2KFX that I used before the acquisition of my K3. It is a reliable and resilient amp and I have had the ALC connected to the K3 for a year. However
I tend to take Don Wilhelms advice and there have been times when the ALC and SWR inputs to the AMP’s logic seem to fight each other, so I just disconnected
the ALC and will report any issues….silence = happiness.

I mourn the the shutdown THP after the earthquake/floods. It was a terrific company with a lot of great products with leadership in the mould of Elecraft.
