TELEMETRY CHANNELS
ACMA regulations have allocated Channels 22 and 23
for telemetry-only applications and have prohibited the
transmission of speech on these channels. Consequently the
TX3350 has a transmit inhibit applied to channels 22 and 23.
In the event additional telemetry/telecommand channels
are approved by the ACMA, these channels shall be added
to those currently listed where voice transmission is
inhibited. Currently transmissions on Channels 61, 62 and
63 are also inhibited and these channels are reserved for
future allocation.
