Neil,
FWIW, the DC4 power supply by Drake was a high frequency (330Hz square wave per
manual) inverter with transformer for the TX. But they also had a winding and
plug for a 115 volts to run a RX. So I would think about any reasonable
inverter would work fine on the RX.
see:http://www.wb4hfn.com/DRAKE/DrakeManuals/DC4/Manual_DC4.htm
If you're so inclined to build something, I am guessing that you could use an
old battery charger transformer and a pulse generator circuit feeding the 12
volt (actually 24volt CT) side. Then the 120 volt output to the RX plug. 60 Hz
transformers generally do fairly well with higher audio frequencies. Depending
on your junk box and ability to scrounge I would think it would come in under
$30. see:http://www.i4at.org/lib2/inverter.htm I am sure further google
searches may turn up better circuits.
