E/PROM PROGRAMMING

2. Band 5B utilizes a 9.6 MHz TX IF, 12.5 KHz reference frequency and
high side local oscillator injection. This band selection allows the
programming of "splinter" frequencies at 12.5 KHz channel spacings.
The 70-2132 12.5 KHz Channel Spacing Kit must be added to the radio to
allow operation on these frequencies. Only those frequencies which are
evenly divisible by 12.5 KHz may be programmed in Band 5B. If full
specification receiver performance is required on adjacent 12.5 KHz
spaced channels, the 12.5 KHz 1st. / 2nd IF Filter Kit 70-2135 should
also be added to the transceiver.
3. Band 5C allows the programming of "splinter" frequencies with low
side local oscillator injection instead of high side. To utilize this
band, both the 70-2132 12.5 KHz Channel Spacing Kit and the
appropriate 70—2175/2176/2177 Low Side Injection Kit must be installed
in the radio. Other band selection codes may not be used after this
conversion .
4. Band 5D, BAND CODE 0D, utilizes a 10.24 MHz TX IF, 2.5 KHz
reference frequency and high side local oscillator injection. This
band selection allows mixed programming of standard 15 KHz spaced
channels and 12.5 KHz "splinter" frequencies. To utilize this band,
the 70-2138 2.5 KHz Channel Spacing Kit must be installled.
NOTE: Radios containing the 70-2138 kit can be programmed on_l.X with
programmers configured with "0.0" and later software.
5. Band 5E, BAND CODE 0E, allows the mixed programming of standard 15
KHz spaced channels and 12.5 KHz "splinter" frequencies with low side
local oscillator injection instead of high side. The 70-2138 kit and
the appropriate low side injection kit must, be installed in the radio.
CHANNEL PROGRAMMING
When the band selection has been, channel frequencies and auxiliary
codes can be entered as outlined in the 70-1000 Operator s Manual.
Note that. Auxiliary Code "0" (tone disable) is automatically
programmed for each transmit and receive channel if no other code is
entered. Auxiliary data may be programmed in E/PROM even if the CTCSS
option is not installed in the transceiver.
If the transceiver installation causes all power to be removed from
the unit by the ignition switch, it. should be noted that, the powerup
channel will always by the lowest numbered channel programmed. As long
as power is supplied to the radio power/auxiliary connecter, the
channel, in use at unit, turn-off will be displayed at. turn-on.
SCAN PROGRAMMING
Up to 64 channels can be programmed in each of 2 scan groups. Refer to
the 70-1000 Operator's Manual for programming details.
FUNCTION CODE PROGRAMMING
Eight transceiver functions are programmable by function code inputs
