DSB Transmitter for 80 meter
I have designed a double sideband transmitter. DSB.
There I use 5 radio tubes and a modern SI5351 oscillator.


Here is the finished transmitter together with the receiver R-390A.
The microphone is an old crystal microphone.





Here we see the test signal. A triangle signal is sent
in at the microphone input and a DSB signal comes out.





Here is my video.
