Hello John To start with Ill tell you a little about me. I am a broadcast Engineer and maintain Mostly AM stations. Actually the Company I work for has 55 AM stations. I also work for a consultant as a field Engineer.and have retuned many rigs to new frequencies. The Problem I found with the RCA is the output Network. I for one like to keep the Broadcast Rigs as close to origonal as possible. For 160 Meters with the RCA BTA series. all you really need to do is remove one Cap and then change the Taps on the Coils. no other mods are needed. However to move the Rig to 75 meters. it can Be done but you have to Build an entirly New output network. I am not saying It cannot Be Done. I feel the Rig has more Value if kept close to Factory origonal. The guy who had My BTA 500r before me attempted to do just as the above. He rebuilt the output network I checked his work. seemed ok,but the rig ran into oscilations and Eventually smoked.. I bought the transmitter and rebuilt the origonal network fixed a few smoked Items.replaced all the caps and resistors in the oscilator board. Tuned the ouput with the Slider can Cap in the Coil the RCA stock tuning to Center. to 1.885 Turned on the AC and the rig came back to life. If you goto my calls KA2CAF in QRZ.com I have links to this particular transmitter also My Collins 300G and my Gates BC-1H1
