To limit scanning (and manual tuning) within a particular frequency range, you can use the
Programmable Memory Scanning (PMS) feature, which utilizes five special-purpose memory
pairs (“
M-P1L
/
M-P1U
” through “
M-P5L
/
M-P5U
”). The PMS feature is especially useful in
helping you to observe any operating 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-PxL
” and “
M-PxU
”), where the “U” channel represents the Upper frequency
limit, and the “L” channel represents the Lower frequency limit.
2. Press the [
FUNC
] key momentarily, then rotate the
SELECT
knob, as needed, until
Multi Function Row “f” [
ARTS, SRCH, PMS
] appears on the display.
3. Press the [
C
](
PMS
) key. The “
PMS-x
” indication will appear at the upper left corner of
the LCD, signifying that the PMS feature is engaged. Tuning and scanning (by pressing
the [
A
](
SCN
) key on the Multi Function Row “g” [
SCN, PRI, DW
]) are now limited
within the range between the selected PMS memory pair, keeping operation inside this
programmed range.
Example
: Limit tuning and scanning to the frequency range 144.30 - 148.00 MHz, to pre-
vent encroachment into the “Weak Signal” (SSB/CW) portion of the 2-meter band:
1. Press the [
V/M
] key, as necessary, to recall the VFO mode. Tune the
SELECT
or
DIAL
knob to 144.300 MHz.
2. Press the [
FUNC
] key momentarily, then rotate the
SELECT
knob, as needed, until
Multi Function Row “b” [
MW, SKIP, TAG
] appears on the display.
3. Press the [
A
](
MW
) key momentarily, then turn the
SELECT
knob to select memory
channel “
M-P1L
.”
4. Press and hold in the [
A
](
MW
) key for one second to write the VFO frequency into “
M-
P1L
.”
5. Now, tune the
SELECT
or
DIAL
knob to 148.000 MHz.
Press the [
A
](
MW
) key momentarily, then turn the
SELECT
knob to select memory
channel “
M-P1U
.”
6. Press and hold in the [
A
](
MW
) key for one second to write the VFO frequency into “
M-
P1U
.”
7. Press the [
FUNC
] key momentarily, then rotate the
SELECT
knob one click clockwise
to recall Multi Function Row “f” [
ARTS, SRCH, PMS
].
8. Press the [
C
](
PMS
) key momentarily. Tuning and scanning are now limited to the 144.30
- 148.00 MHz range until you press the [
V/M
] key to return to memory or VFO operation.
