Minima PA Driver and Rx Preamplifier.
I start at locking in the book Experimental Methods in
RF Design, page 2.32. There was a good example on a amplifier for higher Pout
then I need, so I lower the current. I do a test and find it working. I add a Rx
preamp switchable in/out amplifier, copy from a QRP station.
Made a PCB and it is now finished.
The Result, gain 1.8 MHz 32 dB, 30 MHz 29 dB.
