    Socket on the back of some transceivers

    All the E.C.I. tube radios (Couriers, Aircastles, Fannons, Realistics) had nine pin connectors for power. Depending on how the plug was wired it could power the radio with AC or DC.

    Or you could just buy a complete kit from a place like Klondike Mikes.

    Uniden 980 alignment notes

    That post is from 2014. If you click on his name you'll see he hasn't posted anything since 2017. He probably isn't on here anymore.

    Courier Spartan 40 channel ssb with a channel dial mod???

    I didn't realize you were from Australia. I remember reading that there were only 18 channels allowed there back then, and I remember CPI had their CP-180 model with 18 channels just for Australia.

    I Don't Know if it is "bad form" to ask about one "forum" on another one......

    Realistic TRC 457 heats up, drifts, un adjustable

    This may help you, the original Realistic Factory Service Manual for the TRC 458. It's the same radio as the 457 but doesn't have the clock. Also, the TRC 449 manual may help. It was the mobile version of the radio.

    Realistic TRC 457 heats up, drifts, un adjustable

    That was in the Cobras. The Presidents and Realistics already have it bolted to the heat sink.

    Schottkey diode/transistor opinions

    The swap to the Sanyo 2SC2999E never much amounted to anything. Someone who didn't know how to read data sheets and didn't understand that there is no test standardization amongst transistor manufactures saw that the noise level was slightly lower than the 2SC1675 and 2SC1674 transistors and...

    CPI 2000 issues

    Something looks wrong with pin 10 of that chip, and it doesn't look like the chip is seated all the way into the socket on the one end.

    CPI 2000 issues

    Those two wires soldered to pins 1 and 3 are on U600G. As others have stated, it's one of the programmable dividers. It was done for a 5KC mod to get the "A" channels. Here is the SAMS #168 manual for this radio. It's actually for the 400 mobile, but is very similar to the 2000. It's the only...
