Continue working on SDR Box
Some improvements.

Packages — fans arrived
48v fans for amplifier.
5w HF amplifier
It’s for using TRX-DUO as signal generator.
Received big radiator, but…
Something went wrong while transporting.
Test amplifier with mrf9120
Just received a few mrf9180 and one mrf9120, decided to finally test it with mrf9120.
Concept of the box has changed :)
Now i think it’s better to insert all filters in box and not to insert TRX-DUO (or another SDR).
Last (i hope) holes in the plate drilled.
Drilling holes in a coper is a pain.
And bigger pain is to cut the thread in it.
MRF9180 amplifier — feeding transistor via balancing choke
Let’s try to add balancing choke to the schematics — feed sources from 4 turn choke for each transistor (8 turns summary) with power connected to the central point.
