(Preset and Scanning)
You can set the transceiver to tune or scan on/y
within a preset band. Ten special memories (which
form five preset pairs when programmed) are avail-
able for PTS operation. Each pair ,
and define a preset. tuning
and scanning
range, with an upper and lower limit
stored in a “L” and “U” memory.
Although PTS memories are recalled, viewed and
programmed the same as regular memories, they
are ignored during regular memory scanning.
Let’s try an example:
Program I and to limit operation (tuning and
scanning) to 444.00 446.00 MHz:
From either VFO, copy 444.00 into I, and 446.00
into I as you would for regular memories.
Press to switch to MR mode (if needed), and
recall either memory of the preset pair (it makes no
difference if you select or I).
Press again to activate memory tuning (MT
blinks). Turning the knob now tunes the memory
up/down the same as before, however, operation is
now restricted to 444.00-446.00 MHz.
To scan, hold for second. Just as with
regular VFO scanning, a double beep sounds each
time the scanner reaches a preset band edge,
unless the beeper is disabled (page 50).
Channel Resolution for PTS Limits
Although you can tune and scan in the default chan-
nel
step size during PTS operation, you can only
store
even or resolution frequency limits
into PTS memories.
For example, while 146.00 or 146.100 are accept-
able preset limits, 146.035 or 146.150 are invalid
(they would be rounded down to the nearest 1
channel).
If ARS or manual repeater shift is activated, the
offset is applied automatically when you transmit
(even if the resulting transmit frequency is outside
the programmed limits).
To exit PTS, press to return to MR operation,
then to return to a VFO.
Note you cannot activate PTS tuning or scan-
ning if either
PTS
memory is marked for skip-scan-
ning, or hidden.
