Test 2 stages 2 x BFG591 + 2 x RD15HVF (got 20w output)

Input unmatched as it’s just goes through 1:1 transformer. Real input power with correct transformer will be lower.

I’ve not tested it on the high frequencies as output power from generator is lower that needed for the unmatched input.

Idle current is 500mA. 13.8v feed.

20m no LPF:

40m no LPF:

Added Aliexpress cheap LPF (I spend some time to set it up with correct inductances):
