This feature allows you to set sub-band limits for either scanning or manual VFO opera-
tion. For example, you might wish to set up a limit (in North America) of 144.300 MHz to
148.000 MHz so as to prevent encroachment into the SSB/CW “Weak Signal” portion of
the band below 144.300 MHz. Here’s how to do this:
1. Set the radio to the VFO mode by pressing the [ VFO
(
PRI
)] key, if necessary.
2. Using the techniques learned earlier, store (per the above concept) 144.300 MHz into
Memory Channel #L1 (the “L” designates the Lower sub-band limit).
3. Likewise, store 148.000 MHz into Memory Channel #U1 (the “U” designates the
Upper sub-band limit).
4. Confirm the radio is in the VFO mode, press and hold in the [
VFO
(
PRI
)] key for one
second, and rotate the
DIAL
knob to select the desired PMS frequency pair (
PMSxx
),
then press the [
VFO
(
PRI
)] key.
5. Now, press and hold in the [
MR
(
SKIP
)] key for one second to initiate Programmable
(Band Limit) Memory Scan. Scanning will now be limited within the just-programmed
range.
6. 10 pairs of Band Limit memories, labeled L1/U1 through L10/U10 are available. You
therefore can set upper and lower operation limits in multiple segments on the band, if
you like.
