107.95 x 41.148 x 35.052 mm
Emission Designator: HMa-A1: 44K3F3E
HMa-B1: 57K9F3E
Specifications subject to change without notice.
Operating Frequencies:
Band A1: 470.100 - 537.575
Band B1: 537.600 - 607.950
Frequency Selection Steps: Selectable; 100 kHz or 25 kHz
RF Power output: Selectable 50/100 mW
Pilot tone: 3.5 kHz deviation (Nu Hybrid)
Frequency stability: ± 0.002%
Spurious radiation: Compliant with ETSI EN 300
422-1 v1.4.2
Equivalent input noise: –125 dBV (A-weighted)
Input level: Nominal 2 mV to 300 mV, before limiting.
Greater than 1V maximum, with limiting.
Input impedance: 1K Ohm
Input limiter: Dual envelope “soft” limiter; greater
than 30 dB range
Gain control range: 55 dB; panel mounted
membrane switches
Modulation indicators: Dual bi-color LEDs indicate modulation
of -20, -10, 0, +10 dB referenced to full
modulation
Audio Performance (overall system):
Frequency Response: 35 Hz to 20 kHz (+/-1dB);
Low frequency Roll-off: Adjustable for -3dB @30, 50, 70, 100,
120 or 150 Hz)
THD: 0.2% (typ. 100 Hz to 20 kHz - see graph)
SNR at receiver output:
SmartNR no limiting w/limiting
OFF 103.5 108.0
NORMAL 107.0 111.5
FULL 108.5 113.0
Note: The dual envelope “soft” limiter provides exceptionally good handling of
transients using variable attack and release time constants.
Once activated, the limiter compresses 30+ dB of transmitter input range into 4.5
dB of receiver output range, thus reducing the measured figure for SNR without
limiting by 4.5 dB.
Input Dynamic Range: 125 dB (with full Tx limiting)
