2. Set the FT-857 for operation on another memory channel, or on a VFO frequency.
3. Press the [F] key momentarily, then rotate the MEM/VFO CH knob, as needed, until Multi Function Row “g” [SCN,
PRI, DW] appears on the display.
4. Press the [B](PRI) key momentarily to start the “Priority” monitoring (the “P” icon will appear at the upper of the
frequency display). During Priority monitoring, the displayed frequency will shift to the Priority memory briefly
about five seconds, while the receiver check for the presence of a signal.
5. When no signal appears on the Priority memory (i.e. the squelch remains closed), you can tune, transmit and receive
on the VFO, or select and operate on other memories.
6. If a station you wish to talk with appears on the Priority channel, press the PTT switch momentarily while receiving
their signal (no transmission will occur) to halt Priority scanning. Otherwise, when a signal appears on the Priority
channel, Priority monitoring will just pause on the channel. Priority monitoring will resume.
7. To cancel Priority monitoring, press again the [B](PRI) key.
Programmable Memory Scan (PMS) Operation
To limit scanning (and manual tuning) within a particular frequency range, you can use the Programmable Memory
Scanning (PMS) feature, which utilizes 10 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”)
2. Switch to the Memory mode by pressing the V/M key once, then rotate the DIAL to select the Memory channel “M-
PxL” or “M-PxU”.
3.
Press the [F] key momentarily, then rotate the MEM/VFO CH knob, as needed, until Multi Function Row “f” [ARTS,
SRCH, PMS] appears on the display.
4.
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 & scanning to the frequency range 144.30 - 148.00 MHz
1. Press the V/M key, as necessary, to recall the VFO mode. Tune the MEM/VFO CH or DIAL knob to
144.300 MHz.
2. Press the [F] key momentarily, then rotate the MEM/VFO CH knob, as needed, until Multi Function Row “b” [MW,
SKIP, TAG] appears on the display.
