I wonder if anyone caught Paolo's article in ER this month regarding detail
differences in the R-390 and R-390A?

I think one big reason the heater strings are 25.2V in the R-390(and R-389
and -391) is that there was at least a planned DC power supply module with a
dynamotor for 28 VDC operation.

Has anyone ever seen such a beast? It also explains the GRC series 4 pin
input connector.

Mark what kind of antenna are you using with those receivers? Thanks Jeff

> Congrats to Joe Long for his excellent article in this months "ER" magazine issue on the BC-1206. This little receiver and its other variants allowed single engine and larger aircraft to navigate the A/N airways with precision. Arriving at Destination with an A/N beacon nearby the aircraft could shoot a non-precision approach and penetrate low ceilings.   Once near the airport traffic pattern the pilot could receive instructions from the tower and acknowledge by rocking the wings or flashing a light etc. A lot of capability in a 4 pound box. You could even install the receiver with a battery   in a aircraft that did not have an electrical system.
