MPX96 LF Program Chart

The MPX96 can be operated at frequencies down to 54 MHz for special export operation. Suitable modifications must be made to the VCO and RF power Amp sections. Bandwidth coverage at any one slug setting of L1 is approximately 15-18 percent. It is not possible to cover the range shown in chart with one slug setting of L1. See Manual for details on setting L1 slug to cover the desired range. L1 is normally set with the MPX96 programmed for the lowest desired frequency. However, this entire range can be covered with three different settings of the slug. Note that in order to reach frequencies below 70 MHz some coverage of the higher frequencies in the 88-108 MHz band may be lost.

Note on switch programming::
         a "1" corresponds to switch section open (logical 1)
         a "0" corresponds to switch section closed (logical 0)

         S1 sets the logic levels at the programming inputs of IC6

         Frequencies are shown for ODD 200 kHz spaced channels. These are
       with J1 not installed and pin 11 IC6 at logical 1

         For operation on EVEN channels, install J1 so pin 11 IC6 is at
       ground or logical 0. Subtract 0.1 MHz from freq indicated in chart.
       i.e. 88.1 settings will produce 88.0, 72.5 will produce 72.4, etc.
