[App_rpt-users] iaxRPT does not receive

Typically 9600 baud is equal to discriminator audio and 1200 baud is equal to de-emphasized / processed audio.

George,
I see I did not completely answer your questions about he audio so here is the terminal run on the tests you suggested.
test*CLI> radio tune rxsquelch
Current Signal Strength is 583
Current Squelch setting is 740
test*CLI> radio tune rxnoise
tune rxnoise maxtries=12, target=27000, tolerance=2750
tries=0, setting=2, meas=6144
tries=1, setting=9, meas=20442
tries=2, setting=12, meas=25897
tries=3, setting=12, meas=25857
tries=4, setting=12, meas=25885
tries=5, setting=12, meas=25832
tries=6, setting=12, meas=25798
DONE tries=6, setting=750, meas=25798, sqnoise=13342
INFO: RX INPUT ADJUST SUCCESS.
Rx noise input seems sufficient for squelch.
The 9600 baud data port looks to be the least filtered audio out of the radio and so I selected that for the source. The speaker audio and 1200 baud audio looked to be filtered. It will take a while to determine how good the receive audio is, but this is a test setup for learning purposes. So problems found and solved here in the shack are worth it. Then when the knowledge is applied to the actual repeater controller and VoIP links, maybe it will all work and sound good.
Thanks again.
73,

Ron, you're describing two different things here...or I'm not decoding your words. Does node 28174 that you have work ok, connect to outside world, make contacts that work? If you don't know that the node is working right I'd hold off troubleshooting iaxrpt till I knew that teh node itself was ok.
If your node is ok then distribution, URI wiring, ptt connections, etc really are not a matter. iaxrpt should connect.
Try, from command line:
rpt showvars 28174
Mine, no received signal:
radio*CLI> rpt showvars 2360
Variable listing for node 2360:
RPT_TXKEYED=0
RPT_NUMLINKS=3
RPT_LINKS=3,T27849,T27891,T3341697
RPT_NUMALINKS=2
RPT_ALINKS=2,27849TU,3341697TU
RPT_ETXKEYED=0
RPT_RXKEYED=0
RPT_AUTOPATCHUP=0
-- 8 variables
Here's witht he repeater keyed, signal on input:
radio*CLI> rpt showvars 2360
Variable listing for node 2360:
RPT_ETXKEYED=1
RPT_TXKEYED=1
RPT_RXKEYED=1
RPT_NUMLINKS=3
RPT_LINKS=3,T27849,T27891,T3341697
RPT_NUMALINKS=2
RPT_ALINKS=2,27849TU,3341697TU
RPT_AUTOPATCHUP=0
-- 8 variables
See the two highlighted?
I'd be curious if your receiver is in an unsquelched mode and timed out...
Also rpt stats 28174
SEe if you're timed out..??
I connected to your node about 10:50PM central, and it kept sending unkeys at about 5 second intervals. So something's not configured right in general there, and I'd check all that stuff before attempting iaxrpt.
I have no idea about the pins on the URI, I modified my own USB fob, and/or use the paralell port for signalling. However, I think you are speaking of the radio audio oiut when you speak of 9600 baud data out. Are you certain that there is no filtering at all at that point?
Another command is radoi tune rxsquelch
The numbers should be well between 0 and 999, and the squelch setting should be about 100-125 higher than signal strength. If your signal strength is showing very thigh...999 I'd say the audio calibrations were in error or your audio output is filtered in some way. It really needs to be discriminator out.
What do you have duplex set to in rpt.conf?
