The rugged IPT TR9 Transmitter is designed to be used
for the wireless transmission of audio and control
signals to your IPT in-car video system. The TR9
transmits in the 902Mhz to 928Mhz band and is factory
selected to one of eight frequencies. A CTCSS PL
encoder is built into the transmitter to sub segment each
of the 8 RF frequencies into 47 channels and is normally
factory selected for PL tone frequency. The optional
digital encoder used for remote control of six user
selectable functions is also factory selected for 1 of 243
unique address codes.
