Frequencies Quartz PLL frequency synthesizer circuit (25 kHz step)
Frequency stability
▪ ± 2,5 ppm (in the rated temperature range)
▪ ± 2.5 kHz (in the rated temperature range)
Temperature range -10 ÷ +55 °C
Max RF power
▪ 50 mW (ERP) when high power selected
▪ 10 mW (ERP) when low power selected
Spurious emissions < 2 nW
Modulation wideband FM, with 50 µs pre-emphasis
Nominal deviation ±40 kHz (Peak deviation = ±56 kHz)
Telemetry feature MTP30 transmits also a digitally modulated sub-carrier, suitable for:
▪ tone-squelch operating ▪ remote battery monitoring ▪ optional PTT (push to talk) operation
AF input connector Configurable on ‘mic’ display menu in 3 options:
▪ ’2 wires’: Æ gain selectable -40 ÷ +40, no bias voltage
▪ ‘2 wires + bias’: Æ gain selectable -20 ÷ +40, 5.5 V bias voltage (4k7 internal resistance)
▪ ‘3 wires + bias’: Æ gain selectable -20 ÷ +40, 5.5 V bias voltage (4k7 internal resistance)
AF input level 80 dB adjustable range from -60 dBu (775 uV) to 20 dBu (7.75 V) at nominal deviation (1 kHz), adjustable in 2 dB steps
Max. input level +26 dBu (15.5 V) at clipping, +20 dBu (7.75 V) at nominal level
Noise-Reduction ENR (Wisycom Extended-NR), with independent Attack-time and Recovery-time
AF bandwidth
▪ 45 Hz ÷ 21 KHz (3dB)
▪ 55 Hz ÷ 20 KHz (1dB)
Distortion < 0.3 % (0.15 % typ.)
