The Regency HR-2S "Transcan" used pushbutton control to scan any or all of its 8 channels. A received signal locked the 2 meter FM rig in the receive mode, then resumed scanning when the signal dropped. Power output was 15 watts. It had an internal117 VAC supply. The HR-2MS model used 12 VDC power for mobile operation.
Regency called Transcan a "new reception concept" in FM transceivers. The receiver section of the transceiver scans as many as 8 crystal-controlled channels anywhere in the band. Upon reception of a signal, scanning stops, and the receiver monitors the frequency being used. At the end of the transmission the receiver resumes scanning at the rate of 15 channels per second.
Each channel can be quickly programmed in or out of service by the push of a button so the receiver will not be locked onto one frequency if the channel is tied up. All eight transmit channels are also pushbutton selected. When a transmit button is pushed the receiver stops scanning and locks on the receiver channel paired to the selected transmit frequency.
Sensitivity: 0.35 uV for 20 dB quieting, selectivity at 6 dB down 16 kHz, 45 dB image rejection and 60 dB spurious rejection. Modulation acceptance is I5 kHz and audio output is 5 watts into a built-in front panel speaker.
The transmitter runs 15 watts output across the entire 144- to 148-MHz band and has adjustable deviation zero to ±15 kHz. Spurious and harmonic emissions are measured at 55 dB or more below the carrier.
Power requirements; 117 VAC.
