QST, Dec 1975, p. 115. QST, Nov 1976, p. 133 (6 meter version) QST, Nov 1977, p. 170. QST, Nov 1977, p. 105. (full list of accessories) Still being advertised as "new" in 1977. Distributed by Amateur Wholesale Electronics. Made by Kyokuto Denshi Kaisha Ltd Sometimes seen as FM-144, or FM144. All solid state PLL digital synthesized • 5KHz steps - 144-149 MHz LED digital readout • MARS and CAP • 5 MHz Band Coverage - 1000 Channels • Priority Channel • Audio Output 4 Watts • 15 Watts Output • 15 pole filter, monolithic crystal filter and automatic tuned receiver front end. • FREQUENCY RANGE: Receive: 144.00 to 148.995 MHz. 5 KHz steps (1000 channels). Transmit 144.00 to 148.995 MHz, 5 KHz steps (1000 channels) + MARS and CAP. • • FULL DIGITAL READOUT: Six digits provide direct frequency readout assuring accurate and simple selection of operating frequency • AIRCRAFT TYPE FREQUENCY SELECTOR: Large and small coaxially mounted knobs select 100KHz and 10KHz steps respectively. Switches click stopped with a home position facilitate frequency changing without need to view LED'S while driving and provides the sightless amateur with full Braille dial as standard equipment • FULL AUTOMATIC TUNING OF RECEIVER • FRONT END: DC output of PLL fed to varactor diodes in all front end RF tuned circuits provides full sensitivity and optimum intermodulation rejection over the entire band. • TRUE FM: Not phase modulation for superb emphasized hifi audio • FULLY REGULATED INTEGRAL POWER SUPPLIES: Operating voltage for all circuits.12, 9, and 5 volt power have independently regulated supplies 12v regulator effective in keeping engine alternator noises out and protects final transistor from overload • MONITOR LAMPS: 2 LED'S on front panel indicate (1) incoming signal-channel busy, and (2) unlock condition of phase locked loop. • DUPLEX FREQUENCY OFFSET: 600 KHz plus or minus, 5 KHz steps. Plus simplex, any frequency. • MODULAR COMMERCIAL GRADE CONSTRUCTION: 6 unitized modules eliminate stray coupling and facilitate ease of maintenance. • ACCESSORY SOCKET: Fully wired for touch-tone, phone patch, and other accessories. • RECEIVE: 0.25 uV sensitivity. 15 pole filter as well as monolithic crystal filter and automatic tuned 
LC circuits provide superior skirt selectivity • AUDIO OUTPUT: 4 WATTS. Built in speaker. • HIGH/LOW POWER OUTPUT: 15 watts and 1 watt, switch selected. Low power may be adjusted anywhere between 1 watt and 15 watts, fully protected -short or open SWR * PRIORITY CHANNEL: Instant selection by front panel switch. Diode matrix may be owner re-programmed to any frequency (146.52 provided) • DUAL METER: Provides "S" reading on receive and power out on transmit References Scanner modification.
