This feature allows you to set sub-band limits for either scanning or manual VFO operation.
For example, you might with 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 [
V/M ( MW )] key, if necessary.
2. Using the techniques learned earlier, store 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 Up-
per sub-band limit).
4. Switch to the Memory mode by pressing the [ V/M
(
MW
)]
key once, then rotate the
DIAL
knob to select Memory
Channel “
L1
.”
5. Press the [
BAND ( SEL )] key momentarily to start PMS
operation; the “ ” label will appear on the display.
Tuning and scanning (engaged by pressing the
[
SCAN
(
SEL
)] key momentarily) will now be limited within the just-programmed range.
6. Fifty pairs of Band Limit memories, labeled L1 / U1 through L50 / U50 , are available.
You therefore can set upper and lower operation limits on a number of bands, if you like.
