BC-1H1 remote and AUDIO in

Post by HadYourPhil »

I've inherited one of these as a backup transmitter and a previous engineer has "customized" the remote stuff. As the manual does not say, what voltages am I dealing with on the metering and is this a transmitter with high voltages on the remote start/stop, plate on/off controls? Seems like it is, but it's been a long time.

ALSO... What is the polarity of the audio in? Yeah, I know I can futz with the processing, but it would be nice to hook it up right the first time The last three connections on the bottom strip (TB-2) are the audio in connections.

Not sure on that exact model, but many of the Harris transmitters of that era had 110v on remote connections.

Typically you had to have a normally closed for filaments off (e.g.--opening circuit stopped the filaments), momentary to common started; same for plates, normally closed for plate off, momentary start.

Metering voltages in the range 1~3 volts or so

TB1-15 & 17 Plates on momentary
TB1-20~21 Plates off (normally closed)
TB1 9 & 13 low power mode (momentary)
