SCANNING

PROGRAMMABLE (BAND LIMIT) MEMORY SCAN (PMS)

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.
