4.4 CHANNEL FREQUENCY SELECTION
Early radios have their frequencies programmed by a diode matrix as
described in Section 4.4.4. For radio units shipped after July 2012 and
equipped with a USB port, please refer to Appendix A (TiL TDP-90
Programming Software User’s Guide for USB Programmable AM Series
Transceivers) - Document 11RE439.
4.4.1 Operation in the Transmit Mode
Transceiver Model 90-6R, Part Number 861605-2, Series 1, has Channel 1 operating frequency
pre-programmed at 121.9000 MHz. Other channels are not pre-programmed. Before
programming any other frequencies, perform an operational check, on Channel 1 at 121.9000
MHz, as outlined in paragraph 4.4.6. If there is any operational deficiency or equipment
malfunction, return transceiver to the manufacturer. Before use it is necessary to pre-program the
operating frequency for each channel to be used.
4.4.2 Frequency Range
The transceiver may be programmed for up six frequencies over the frequency range 117.975
MHz to 138.000 MHz with 25 kHz channel spacing.
4.4.3 Preparation
Frequency Set-Memory Module A5 must be removed from the transceiver to allow frequency pre-
programming as follows:
(1)
Place the transceiver on a bench with the top cover of the transceiver located on the
bench and the bottom cover exposed.
(2) Remove and retain twelve screws and lockwashers securing the bottom cover to the
main chassis of the transceiver.
(3) Remove and retain the bottom cover.
NOTE:
A folded ribbon cable is laid across the Frequency
Set-Memory Module A5. Carefully move this cable to
one side while handling the Frequency Set-Memory
Module A5.
(4)
Remove and retain four screws and lockwashers securing the Frequency Set-Memory
Module A5.
(5) Gently pull, with a rocking action, the Frequency Set-Memory Module A5 in an upwards
direction until its male pin connector A5J1 is disengaged from its mating connector A2J2
on Audio Synthesizer Module A2. Remove Module A5 from the transceiver.
