PTS (Preset Tuning and Scanning)You can set the transceiver to tune or scan on/ywithin a preset band. Ten special memories (whichform five preset pairs when programmed) are avail-able for PTS operation. Each pair (LIWI , L2&U2,L38U3, L4&U4, and L5&U5) define a preset. tuningand scanning range, with an upper and lower limitstored in a “L” and “U” memory.Although PTS memories are recalled, viewed andprogrammed the same as regular memories, theyare ignored during regular memory scanning.Let’s try an example:Program L I and u 1 to limit operation (tuning andscanning) to 444.00 - 446.00 MHz:0 From either VFO, copy 444.00 into L I, and 446.00into U I as you would for regular memories.c]l Press “@r”5* to switch to MR mode (if needed), andrecall either memory of the preset pair (it makes nodifference if you select L I or fi I).m Press “r5* again to activate memory tuning (MTblinks). Turning the knob now tunes the memoryup/down the same as before, however, operation isnow restricted to 444.00-446.00 MHz.0 To scan, hold “?!? for % second. Just as withregular VFO scanning, a double beep sounds eachtime the scanner reaches a preset band edge,unless the beeper is disabled (page 50).Channel Resolution for PTS LimitsAlthough you can tune and scan in the default chan-nel step size during PTS operation, you can onlystore even or 700-kHz resolution frequency limitsinto 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-kHzchannel).IIf ARS or manual repeater shift is activated, theoffset is applied automatically when you transmit(even if the resulting transmit frequency is outsidethe programmed limits).n To exit PTS, press “r’s” to return to MR operation,then “fl* to return to a VFO.I@’ Note - you cannot activate PTS tuning or scan-ning if either PTS memory is marked for skip-scan-ning, or hidden.
