QPX1
2 Watt Multi-channel VHF Transceiver
The QPX1 transceiver module offers a 2
watt RF output VHF radio link, in a robust
aluminium extruded casing. This unit is
ideally suited to applications where
existing lower powered transceivers
provide insufficient range. The QPX1 is a
multi-channel,
narrowband
design,
suitable for licensed and unlicensed VHF
allocations, FCC part 90 operation, and
the 2M amateur band.
