Amp. control board from 60dbm
STM32 based controller.
Finally — finished big LPF
1.2KW LPF
Rear Magura Marta brake dead
So new pair of brakes — front and rear.
High pass filter for the LPF for MRFX1K80
My LPF board contains hight pass filter to split harmonics to the 50Ohm load, instead of returning it to the transistor. Measurements.
AD9851 sine wave generator
Pictures and small description.
Test 2 stages 2 x BFG591 + 2 x RD15HVF (got 20w output)
Some measurements.
Cheap waveform generator to test amps
This generator is based on two DAC904E, so it has acceptable parameters to test amateur HF amplifiers.
Received some stuff
Stuff.
Re:amp post of nostalgia
Flashback to the 90s
Received coils and relays. (LPF)
But no wire 
Looks cool.
