LDMOS power amplifier based on the DSP-7 controller. In Part 2, the PA will be completely assembled and wired, and we do some first tests and see the input switching and the signal quality on the 20m band.

Great video Kurt! I can’t wait to get my DSP7!
Very great project!
Well made i liked the water cooling idea 73
Perfectly as ever :-)
Can you tell me how to automatically switch the antenna from the receiver to the amplifier?
Kurt, Looks nice. I thought that you needed two of the shunts in parallel. Are you using a new shunt?

Charles, in the past I used two shunts 5 milliohms in parallel (2,5 mOhms). But these shunts are quite expensive, so I'm now using one with 1 milliohms. DSP7 allows to select various shunt values.
Please show me how the ALC and PTT radios were connected Andreas
