Yes, the 47 V 8A series regulator supply is in the big cabinet. It also has
all of the protections for the MRF150 transistors. Also a fan for the 100W amplifier module. The transmitter is completely self-contained. There is no attempt at miniaturization. I don't have the time or patience for that level of effort. Each radio is a "test bed" and not a finished product. Just this morning I made two circuit improvements in the receiver. I recently rebuilt the 3.395 MHz IF amp module and the AGC processor module to get rid of a rat's nest of "fixups" and haywire. It looks pretty good now. I do admire the tremendous effort that goes into the compact transceivers, but I don't want to duplicate it. It is the basic radio communications functionality that I care about.
