For example, you might wish to set up a limit (in North America) of 144. 300 MHz to 148. 000 MHz so as to prevent encroachment into the SSB/CW “Weak Signal” portion of the band below 144. 300 MHz. Set the radio to the VFO mode by pressing the [VFO(PRI)] key, if necessary. Using the techniques learned earlier, store (per the above concept) 144. 300 MHz into Memory Channel #L1 (the “L” designates the Lower sub-band limit). Likewise, store 148. 000 MHz into Memory Channel #U1 (the “U” designates the Upper sub-band limit). Confirm the radio is in the VFO mode, press and hold in the [VFO(PRI)] key for one second, and rotate the DIAL knob to select the desired PMS frequency pair (PMSxx), then press the [VFO(PRI)] key. Now, press and hold in the [MR/MW(SKIP)] key for one second to initiate Programmable (Band Limit) Memory Scan. Scanning will now be limited within the just-programmed range. 10 pairs of Band Limit memories, labeled L1/U1 through L10/U10 are available. You therefore can set upper and lower operation limits in multiple segments on the band, if you like. FT-270R OPERATING MANUAL 41 SCANNING “PRIORITY CHANNEL” SCANNING (DUAL WATCH) The FT-270R’s scanning features include a two-channel scanning capability which allows you to operate on a VFO or Memory channel, while periodically checking a user-defined Memory Channel for activity. If a station is received on the Memory Channel which is strong enough to open the Squelch, the scanner will pause on that station in accordance with the Scan-Resume mode set via Set Mode Item 32: RESUME. Here is the procedure for activating Priority Channel Dual Watch operation: VFO Priority 1. Recall the memory channel you wish to use as the “Priority” frequency. Now, set the radio to the VFO mode by pressing the [VFO(PRI)] key. Press the [F/L] key, then press the [VFO(PRI)] key to activate the VFO Priority mode. The display will remain on the VFO frequency, but every five seconds the radio will check the Priority Channel (memory channel) for activity. Press [F/L] [VFO(PRI)] again to disable the VFO Priority mode. Memory Channel Priority 1. Store the frequency you wish to be the “Priority” Channel into memory channel “1. ” 2. Now, set the radio for operation on another memory channel. Press the [F/L] key, then press the [VFO(PRI)] key to activate the Memory Priority mode. The display will remain on the current memory channel frequency, but every five seconds the radio will check the Priority Channel (memory channel “1”) for activity. Press [F/L] [VFO(PRI)] again to disable the Memory Priority mode. [. . . ] ON Default: SAV. OFF FT-270R OPERATING MANUAL 79 SET (MENU) MODE Set Mode Item 50 [VFO. SPL] Function: Enables or disables “VFO Split” operation. ON Default: VSP. OFF Set Mode Item 51 [WID. NAR] Function: Select Wide (±5 kHz) or Narrow (±2. 5 kHz) TX Deviation. Available Values: WIDE/NARROW Default: WIDE Note: If “Narrow” is selected, the receiver audio level is increased slightly to compensate for the reduced deviation. The receiver IF filter bandwidth is not changed via this setting. [. . . ]
