Finished tested and installed and making QSO's off the moon.
I've spent some time and effort and a few $$$ getting this amp the way I wanted it ... ie a genuine replacement for a commercial amp.
Its built around a 1K25 Freescale 50V device. Using a pallet from Jim W6PQL.
The case is from Front Panel Express. All custom made.
Bargraphs are custom made via an ebay supplier.
Runs a cool 1.2KW into the Bird load.
On air it sits at 1KW on the nose and does not move. I have a small input attenuator so the IC-9100 runs about 40W. A bit of added protection.
Already making some good QSO's on moonbounce with it.
Runs 50V at 32A for 1.2KW out 29A for 1KW
Very pleased with it!
Uses a variety of Jims boards for amp controllers, FET switches, RF measurements etc.
Anyway ... started work on 432 now which will be a matching case size and shape
