Remote Control Timeline Moseley was a major supplier of transmitter remote controls. Here's a brief list of the ones I worked on.
- WRC-32 - I'm not sure of the model number on this one. It was vacuum tube based. It had a telephone dial to select channels and a stepper switch at the transmitter site. Control was done with tones. Step and reset were done by interrupting a single tone with the telephone dial. Metering was DC over the phone line.
- PBR-15 - This replaced the telephone dial with a set of push buttons and digital counters. Pushing a button resulted in a tone interruption (reset), followed by a series of pulses emulating a telephone dial. The transmitter site continued to use a stepper for channel selection. Metering was audible FM (voltage to frequency converter) over the telephone line or subaudible over AM or SCA. I seem to recall a DC metering module was also available.
- TRC-15A - This replaced the stepper at the transmitter site with individual relays. Otherwise, it was similar to the PBR-15. Metering was either audible or subaudible voltage to frequency.
- DRS-1A - This was a modem and UART based system. On the metering side, the voltage to frequency converter of previous systems was replaced with a digital panel meter. The digital output of this was formatted and sent to a UART, then to a modem for transmission to the studio. Similarly, button presses at the studio were translated to signals for the UART driving a modem to the transmitter site.
- MRC series - This was the first microprocessor based remote control system by Moseley.
