Some VHF+ stuff.
I was bored and tried to receive some non-HAM and non-voice stuff.

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
