Edit RX: Tone Squelch
MCR42 is able to detect a digital tone squelch generated by
a Wisycom transmitters (
ex. MTH400/MTH300/MTP40/
MTP30 ).
Tone squelch ON: when the tone squelch is enabled the
audio is muted unless the correct carrier is detected. Tone
squelch allows to work with lower RF squelch, increasing the
coverage and the robustness especially in presence of digital
television carriers (DVB-T).
Tone squelch ADV anced: when tone squelch is in advanced
mode the receiver processes also PTT data (push to talk):
activating the command audio output when the button is
pressed on remote transmitter.
When tone squelch is off it is possible to choose where to
put the output between LINE and COM.
The COM column is present only using the Stand alone socket
BPA42-PTT
When tone squelch is set to ON it is possible to choose
where to put the output between LINE and COM.
The COM column is present only using the Stand alone socket
BPA42-PTT
When tone squelch is in advanced mode it is possible to
access a more complex audio matrix where to put the
output between LINE and COM and between PTT rel.
(released) and PTT psh (pushed)
Usually Line is always ticked and Com (PTT) is ticked on “PTT
push.” as additional return channel (intercom).
The COM column is present only using the BPA42-PTT
NOTE: With squelch and tone squelch the audio output is activate when:
Squelch OFF Squelch = 0,3,6,… dBµV
Tone squelch OFF
Always RF level ≥ Squelch
Tone squelch ON
If tone is detected
RF level ≥ Squelch & tone squelch
is detected
