Pingponging of a simplex node

I have a very simple simplex node...speaker out, mic in that's configured:

hdwtype=0
rxboost=1
txboost=0
rxctcssrelax=1
carrierfrom=vox
ctcssfrom=no
rxdemod=speaker
txprelim=no
txlimonly=no
txtoctype=no
txmixa=voice
txmixb=no
invertptt=0
duplex=0
rxondelay=25
rxnoisefiltype=0
eeprom=1

and the rpt.conf is configured with duplex=0....because, when I change
it to a duplex=1, it sits there and bounces back and forth, keying up,
dropping, then courtesy tones key it up, which causes it to key up
again...ad nauseam.

The stanza for the node in rpt.conf is:

rxchannel=Radio/usbxxxxx
duplex=0
erxgain=-3
etxgain=3
scheduler=schedulexxxxx
morse=morsexxxx
macro=macroxxxx
functions=functionsxxxx
phone_functions=functionsxxxx
link_functions=functionsxxxx
telemetry=telemetry
wait_times=wait-times
context = radio
callerid = "WB0YLE Simplex" <xxxx>
idrecording=/var/lib/asterisk/sounds/wb0ylesimplex
accountcode=RADIO
hangtime=1000
althangtime=1000
totime=170000
idtime=540000
politeid=3000
idtalkover=|iWB0YLE
unlinkedct=ct2
remotect=ct3
linkunkeyct=ct8
unlinkedct=ct2
nolocallinkct=0
nounkeyct=0
beaconing=0

it worked for a while with duplex=1...I rang out the cables, no shorts,
etc.

Hmmm...it works, after a fashion, with the duplex set to 0 in rpt.conf,
but, no courtesy tones (I realize that you really don't need them for
simplex, but, it's a nice to have...)

Anyway, suggestions? Did I miss something (that's common...)?

Thx all

Friends don’t let friends use VOX. Just DONT. Its just bad, wrong, and
unacceptable. I left it in the distro as a courtesy but I really never intended
anyone to attempt to use it. Please, just dont.

unfortunately...no way to get a cor sig out of an HT so I can use usb
decoding from the speaker/headphone jack. :frowning: Especially one of those
cheap chinese HTs.

sigh. Cheap/easy/works...pick one...:slight_smile:

Guess I'll have to find an old micor high vhf mobile...more than what I
really want to use...or figure out how to get the sigs out of the TR33 I
have hanging around without totally buggering it up...or...???

No problem, if you leave it in...someone will try to use it...:wink:

My cheap/tiny Alinco has a COR .... a little-known feature. Worked great for
echolink pre-Asterisk.

If you REALLY HAVE to use an HT, use a Motorola, HT-600 or newer.
They have a bridged audio out (for the speaker) coming out of the speaker/mic
connector/cable and it only has DC bias on it when the radio has something
to listen to. Therefore the presence of DC on the speaker lead can be used
as a COR/CTCSS indication.

looking at it, the Wouxun has a receive LED that turns on when
receiving...hmmmm....see what you made me do...pull out the 260 and
measure voltage and the like...

Did you see the new Alinco 220/900 HT they announced at Dayton? Talk
about hitting the two least-used bands (in a lot of areas...)...

Another trick I've done in the past is to glue a phototransistor to
the carrier detect LED on an HT. You don't have to crack open the HT
and it works pretty well. (A downside is that on some HTs the carrier
detect LED will turn on even if the correct CTCSS tone isn't present.
alas.)

Thanks for the great suggestion, Mr. Goldberg :slight_smile:
