Scanning Operation
Programmable Memory Scan (PMS) Operation
To limit scanning (or tuning) within a particular frequency range, you can use the Program-
mable Memory Scanning (PMS) feature, which utilizes special-purpose memory pair (“M-
PL” and “M-PU”). The PMS feature is especially useful in helping you to observe any oper-
ating sub-band limits which apply to your Amateur license class.
PMS setup is simple to accomplish;
1. Store the upper and lower frequency limits of the desired range into the PMS memory
pair (“M-PL” and “M-PU”).
2. Press the key momentarily, then rotate the
knob, as needed, until Operating
Function Row 3 [STO, RCL, PMS] appears on the display.
3. Press the
(PMS) key. The “PMS” indication will appear at the upper left corner of
the LCD, signifying that the PMS feature is engaged. Tuning and scanning are now lim-
ited within the range between the selected PMS memory pair, keeping operation inside
this programmed range.
Example: Limit tuning & scanning to the frequency range 144.300 - 148.000 MHz
1. Press the
key, as necessary, to recall the VFO mode. Tune the
knob or
knob to 144.300 MHz.
2. Press the key momentarily, then rotate the
knob, as needed, until Operating
Function Row 2 [MW, MC, TAG] appears on the display.
3. Press the
(MW) key momentarily, then turn the
knob to select memory chan-
nel “M-PL”.
4. Press and hold in the
(MW) key for one second to write the VFO frequency into
“M-PL”.
5. Now, tune the
knob or
knob to 148.000 MHz).
6. Press the
(MW) key momentarily, then turn the
knob to select memory chan-
nel “M-PU”.
7. Press and hold the
(MW) key for one second to write the VFO frequency into
“M-PU”.
8. Press the key momentarily, then rotate the
knob one click clockwise to recall
Operating Function Row 3 [STO, RCL, PMS].
9. Press the
(PMS) key momentarily. Tuning and scanning are now limited to the
144.300 ~ 148.000-MHz range until you press the
key to return to memory or VFO
operation.
Note
The frequency resolution for these sub-band limits is 100 kHz, although the chan-
nel resolution of the sub-band limit memories in whatever you have selected as
the current step size. As a result, the frequencies stored in these special memories
(M-PL and M-PU) are both rounded down to the nearest 100 kHz for their roles as
sub-band limits. Therefore, in the above example, any frequency between 144.300
and 144.399 MHz may be used to store a lower tuning limit of “144.300 MHz” in
memory M-PL.
