2 Watt Multi-channel VHF Transceiver
Issue 1, 31 July 2012
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, part 95 (MURS)
operation, and the 2M amateur band.
