5 Programmable VFO Tuning Limits

This radio provides the capability of programming the VFO tuning range, in 1 MHz band segments, as well as providing a separate programmable band scan function. (See page 26)

For example you could tell the transceiver that you only wish to tune the 144.000 MHz and 145.000 MHz band segment by specifying any frequency within these two segments.

The Tuning controls would then only tune within these specific bands. The procedure for specifying the bands is described below.

1Select the desired lower tuning limit.

For example you might want to select the 144 MHz band and dial up 144.100 MHz.

2Press and hold the M key for longer than one second, then press the 1 key. This selects the lower frequency limit for the programmable VFO.

3Select the desired upper tuning limit.

For example you might want to select the 145 MHz band and dial up 145.100 MHz.

4 Press and hold the M key for longer than one second, then press the 2 key. This selects the upper frequency limit for the programmable VFO.
