Technical Information and Modifications
Looking for info on repeaters, bases, mobiles (500s, 700s 1000s), TACs, Tactecs, Veetacs, etc.
The 500s were hybrid radios and could be compared to the Mastr-Pro vintage - separate RX and TX strips. The 500s were all solid state except for the final which could be either a normal or an instant-heat tube. The UHF 500s had one useful design feature - the TX PA deck was connected to the exciter with a 50 ohm cable. Removing the PA deck and the transistorized HV power supply turned the 500 into a full duplex continuous duty 10w radio.
Thanks to Lou KF4EON for the RCA logo graphic...
