RCA AT3 Transmitter from Milton Watts
Walking through the local Aviation Museum I noted this and took a picture. I thought this is one piece of equipment that should be in your site possibly under Systems, Tools & Equipment, DOT radio stations
RCA AT3 Trasnmitter 2.5 - 20 Kcs 2 channel, 300 watts, CW MCW AM Push to talk or Voice Operated Carrier.
At Cambridge Bay we used VOC. When working one particular HBC station it was necessary to keep blowing into the mic. As soon as the carrier dropped the HBC station would immediately respond.
When I started as a tech in the Edmonton workshop we were rebuilding AT3 transmitters. Stripping down removing all wiring, repair or replace components and put in a new wiring harness.
