[Milsurplus] [The WS No.19 Group] RE: AR2/AT1 RCAF aircraft radio

Mon Jan 9 09:03:07 EST 2017

⁣I have a couple of AR-2's and an AT-1, with the receiver remote control and the system junction box. I also acquired all the connectors to make up the interconnection cables, with the exception of the plug which would fit the remote. Of course the receiver can be used just with local control.
The AT-1 came to me with an non-original dynamotor strapped in, but it was completely dead. I've been looking for years for a suitable 12 V input dynamotor that could physically fit in the AT-1 but without success. My plan is to take a solid-state 12 VDC input automotive inverter and either quadruple the 120 VAC output or find a suitable plate transformer I can fit in place of the dynamotor (I have a 300W inverter which is really small, so it can fit in there with a lot of room to spare).
If the inverter generates RFI, it is of no consequence in  receive, as it'd only turn on by the original T/R relay circuit when transmitting.
