QPT1
VHF Narrow Band FM 2 Watt multi channel
The QPT1 transmitter module offers a 2 watt
RF output VHF radio link, in either a robust
aluminium extruded casing, or a smaller
footprint PCB mounted shield can. This unit
is ideally suited to applications where
existing lower powered transmitters provide
insufficient range. The QPT1 transmitter is a
multi-channel, narrowband design, suitable
for licensed and unlicensed VHF allocations,
FCC part 90 operation, and the 2M amateur
band. Together with a matching LMR1 or
RX1M receiver a one-way radio data link can
be achieved over a distance of well over
10km (with a suitable antenna)."
Features
Compliant with FCC part 90
PLL synthesizer with TCXO
