Receive Squelch Use the UP/DOWN arrow keys to set Receive Squelch to one of the
following: DPL, TPL, TPL/Quik-Call II, DPL/Quik-Call II, Carrier
Squelch, or Quik-Call II. Carrier Squelch unmutes when carrier is
detected. DPL and TPL unmute when a carrier with proper coding is
detected. Quik-Call II unmutes the radio when the proper tone
sequence is detected. Combinations of TPL/DPL and Quik-Call II can
also be used.
Note: A low-level hum or buzz in the received audio MAY be
experienced when the TPL code OZ (254.1 Hz) is used. This PL
code is at the high end of the sub-audible frequency range and
may be heard in the audio under certain circumstances. Use of
this code should be avoided if possible.
The default is Carrier Squelch.
Quik-Call Type This field will not be visible unless the Receive Squelch field is set to Quik-
Call II or PL/QC II. Use the UP/DOWN arrow keys to select the Quik-
Call II type. The line under Receive Squelch shows the Quik-Call II
type. The Quik-Call II type will be set to one of the following:
The default is Individual Call.
Note: The Quik-Call II frequencies and codes table is provided
in the Appendix of this manual and are assigned on the QUIK-
CALL II OPTIONS screen (F4/F3/F7/F2).
PL Code (Receive) Use the UP/DOWN arrow keys to select the Private Line codes/
frequencies. This field is used to select the Receive PL mode and
frequency or DPL mode and code. This line will be blank unless the
Receive Squelch field is set to PL, DPL, or a combination of Quik-Call II with
PL or DPL.
The Receive PL code can be either a DPL code or a TPL code taken from
the DPL/TPL tables. The TPL frequency may be entered directly from
the keyboard so that TPLs not in the standard table are supported.
When a frequency is entered directly, it will be encoded and then
immediately decoded and re-displayed.
For both Transmit and Receive TPL, the frequency you entered may change
by several tenths of a Hz when you exit this screen and return to it. However,
due to differences in the algorithms for encoding and decoding TPL,
the Receive TPL frequencies will change less often on re-display than
the Transmit TPL frequencies.
Individual
Call
Sets the radio to decode only the A-B individual call tone
combination.
Long Tone B Sets the radio to decode the A-B individual call tone
combination OR the long tone B group call.
Dual Call Sets the radio to decode the A-B individual call tone
combination OR the C-D group call tone combination.
