20m band check of rd16 amp. with 3 devices :)
Before LPF, 60db att. 60-14.5=45.5 dBm eq. 35.48 watt After LPF 60-14.7=45.3 dBm eq. 33.88 watt Diamond meter before attenuator to TinySA
One more RD16 amplifier pt.1
It has non stock capacitors as I don’t have correct ones, so it requires additional tuning. This is a state after assembly.
Small things.
Water pump for mrfx1k80: RD16 kit: Optical encoder for wolf: Had an issue with it. Seller mentions that it works with 5-24v
A tons of PCBs received :)
For RD100 AMP. from WOLF2, just to experiment (and because I have unused RD16 and RD100 transistors): As I don’t need LPF
Modifying MRF9180 board to RD100 with separate bias
Experiment failed — to much problems, but I decided to post it here anyway.
Test 2 stages 2 x BFG591 + 2 x RD15HVF (got 20w output)
Some measurements.
More RD16 amps :)
Was bored 🙂
