Hardrock-50 RF Ham Radio Amplifier plus extras:
$525.00

This is a really great amp! I used it for about 6 months on and and off after I completed its build in conjunction with my Elecraft KX3 radio which I just sold. it works seamlessly with that radio and is built like a tank.

It was fully checked out by Jim, the designer of this amp, and is in perfect working order. It is outperforming the specs. It works with all of the Ham Bands and will switch bands automatically when the radio is switched.

It comes with the internal antenna tuner, the QSK board, the interface for the KX3, and the power in cable. i will also include the operation manual.

I will also throw in the cables that go from the amp to the KX3 in case that is the radio you plan to use it with.

It will produce over 50 watts with an input of about 1.5 watts. The unit is in perfect condition. I hooked it up to my KX1 a couple of times and easily obtained 60 watts output. This amp can make any QRP radio heard when band conditions are not too great.
