Feastures
– PLL synthesizer covers 144-148 MHz in 10 kHz steps
– Separate VXO and RIT for full between-channel tuning
– Simplex or ±600 kHz offset for repeater operation
– Three selectable priority channels
– Multi-mode operation (CW/SSB/NBFM/WBFM)
– Built-in AC and DC power supplies, noise-blanker squelch and rf gain control
– Selectable 1W or 10W output
– Separate S-/power and frequency deviation meters
– Built-in test (call) tone and touch-tone provision
– Excellent sensitivity (.3 µV for 12 dB SINAD)
– "Superior" immunity to crossmodulation and intermodulation
