But as we said we are using a RTCM.
The
short answer is yes.
What you need to do is bring out raw discriminator
to the URI or USB fob. Then configure youfr node for USB radio to have
Carrierfrom = dsp and ctcss from = dsp.
you also need to set the rx
demod to flat.
[usbnode_num]
hdwtype=0
rxboost=1
txboost=1
rxctcssrelax=1
txctcssdefault=131.8
; default pl tone
rxctcssfreqs=131.8 ;rx pl
tone
txctcssfreqs=131.8 ;tx pl tone if
used
;rxctcssoverride=0
carrierfrom=dsp ;carrier squelch
detection
ctcssfrom=dsp ; pl tone
detection
rxdemod=flat
txprelim=yes
txlimonly=no
txtoctype=phase
txmixa=voice
txmixb=no
invertptt=0
duplex=0
rxondelay=0
rxnoisefiltype=0
eeprom=0
Save
your settings and restart your Allstar node so the changes take affect.
Do
your audio calibrations.
Then you will need to set the carrier squelch.
Typically the default squelch setting in Allstar is below the threshold. So you
will get squelch crashes.
Do a "radio tune rxsquelch" at the cli with no
signal at the receiver. It will return the current squelch setting and the
current squelch level.
*CLI> radio tune rxsquelch
Current Signal
Strength is 788
Current Squelch setting is 500
If the squelch level is
below the signal strength then the carrier squelch is open.
Set the squelch
higher than the signal strength by about 80-100 points.
*CLI> radio
tune rxsquelch 820 <enter>
Try the squelch. It should give you a
"fast squelch" for signals that have 20 db quieting or better.
then test the
threshold and see how weak signal will open the squelch. You may have to tweak
the squelch to liking.
Once you have the squelch set correctly then save
thew settings.
*CLI> radio tune save.
You should be good to
go.

After relocating our MSF 5000 to a new location and adjusting the squelch
as low as we could reliably go we noticed that we have a squelch tail. Our
coordination requires that we don’t. It appears that the MSF has a fixed
squelch tail elimination method an no control other than cranking up the
squelch again. This is surprising since we use PL encode / decode. I would
think that the PL would mute as soon as the user unkeys.
With this said is there anything in Allstar that would help with this
situation?
