Pts (Preset Tuning And Scanning) - Yaesu FT-50 Instruction Manual

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 (LIWI , L2&U2,
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 L I and u 1 to limit operation (tuning and
scanning) to 444.00 - 446.00 MHz:
into U I as you would for regular memories.
recall either memory of the preset pair (it makes no
difference if you select L I or fi I).
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.
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-
step size during PTS operation, you can only
nel
store
even or 700-kHz 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 00-kHz
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).
