Channel Spacing:
10kHz, 12.5kHz, 20kHz & 25kHz
(10kHz available for HF variants only)
Intermediate Frequencies:
UHF: 45MHz & 455kHz; VHF: 21.4MHz & 455kHz; HF: 455kHz
Crystal Frequency:
UHF:
Carrier Frequency - 45MHz VHF: Carrier Frequency - 21.4MHz

HF: (Carrier Frequency - 455kHz)/2
Sensitivity:
The sensitivity figures specified are on-body typical, for operation at the ambient
temperature range 18ºC - 25ºC. At temperatures outside of this range, but within the
specified extremes, performance is at an intermediate value. At specified extremes, the
degradation of sensitivity shall not exceed +6dB, relative to the ambient figure.
The battery voltage should be above the low battery trigger point.
Variant Best Position 8 Position Average
RPR 751 15µV/m 25µV/m
RPR 752 15µV/m 22µV/m
RPR 753 15µV/m 25µV/m
Figures quoted are for operation @ 512 Baud data rate. An average degradation of 2dB in
the sensitivity performance should be allowed for, when using 1200 Baud.
