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. 73, Ron WD8SBB --- On Sun, 2/12/12, Neil M Califano <[email protected]> wrote: > From: Neil M Califano <[email protected]> > Subject: [Drakelist] Running R4A off car inverter > To: [email protected] > Date: Sunday, February 12, 2012, 1:12 AM > I'm still interested in running the > Drake R4A of a DC/AC inverter.
