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 73 Bryan WB0YLE Allstar 27294 27295 27710 Echolink WB0YLE-R Morrisville PA
