EPCS (Enhanced Paging & Code Squelch)
The FT-25R/E includes an Enhanced CTCSS tone encoder/decoder and a dedicated
microprocessor providing paging and selective calling features. The squelch permits
directing calls to specific stations (Paging), and receiving only the calls directed to stations
programmed with a similar code (Code Squelch).
The paging and code squelch systems use two pairs of (alternately switched) CTCSS
tones which are stored in the pager memories. Basically, the receiver remains silent until
it receives the CTCSS tone pair that matches those stored in the Receiver Pager Memory.
The squelch then opens so the caller is heard, and the paging ringer (if activated)
immediately sounds. When the PTT switch is pressed to transmit, the CTCSS tone pair
which is stored in the Transmitting Pager Memory will be transmitted automatically.
On the paged transceiver, the squelch will close automatically after the incoming page
ends. Meanwhile, on the paging transceiver, the Enhanced Paging and Code Squelch
system will be disabled after the PTT switch is released, after the paging transmission.
The Enhanced Paging and Code Squelch system may be re-activated again using Set
Mode Item “21 PAGER”, if desired.

This feature allows setting sub-band limits for either scanning or manual VFO operation.
For example, you might wish to set up a limit (in North America) of 144.300 MHz to
148.000 MHz to prevent encroachment into the SSB/CW “Weak Signal” portion of the
band below 144.300 MHz. Here’s how to do this:
1. Set the transceiver to the VFO mode, if necessary.
2. Set 144.300 MHz into Memory Channel L01 (the “L” designates the Lower sub-band
limit).
3. Likewise, set 148.000 MHz into Memory Channel U01 (the “U” designates the Upper
sub-band limit).
4. Press and hold the [#VFO] key.
5. Press the [▲] or [▼] key to select the “PMS-1”
PMS-(number) will change depending on the currently-selected PMS
frequency pair.
6. Press the PTT switch to return to normal operation.
For more details on programmed mode (VFO) scan, refer to the FT-
25R/E Operating Manual.
7. Confirm the transceiver is in the VFO mode, press
the [#VFO] key after pressing the Fkey.
The icon will appear on the LCD display and
the scanning starts just within the programmed
range.
10 pairs of Band Limit memories, labeled L01/U01 through L10/U10
are available. Therefore upper and lower operating limits may be set
for multiple segments on a number of bands, if you like.
