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.
Test 2 stages 2 x BFG591 + 2 x RD15HVF (got 20w output)
Some measurements.
Received coils and relays. (LPF)
But no wire 🙁 Looks cool.
More RD16 amps :)
Was bored 🙂
Paper QSL from Japan and some work.
Paper QSL and work on the 1.2KW LPF and amplifier controller.
48v cooler PWM control via arduino
Noise levels from that fan.
Just received some stuff
Flatpack2 3000 + photo of some big.amp. stuff
Low power amplifiers and radiators
Photos of semi-finished RD16 amp. and mrf9180 amp.
