Hi Ken, YOu need to comment out the CTCSS frequency statements in usbradio.conf if you dont want / need for app_rpt to do the decoding in DSP. Comment these lines out and restart app_rpt and then you'll be in carrier squelch mode only. Hope this helps, Matt G4RKY 2010/1/5 Ken <ke2n@cs.com>
(Asterisk version 0.208)
Struggling with a new DMK URI and first time use of asterisk, in a test setup with an HT as the audio source.
My conclusion is that Asterisk needs to have the CTCSS present no matter what?
Settings are:
carrierfrom=usbinvert ctcssfrom=no rxdemod=speaker txprelim=no txtoctype=notone ; no - CTCSS tone encoding with no hang time
It took me a while to figure out that "invert" means that the COR relay is closed when the signal appears (I would have thought this was not-invert).
My tests show that the repeater function does not key up unless both the COR and CTCSS are present. One, or the other, does not do it. This is not what I expected when I selected "no" for the "ctcssfrom" parameter.
On the other hand, even when you select 'no" for the "txctcss" it still transmits a tone, so maybe it is consistent.
Second issue: The loudest playback sounds cause the URI to go into saturation and distort. I may not have calibrated the levels very carefully, but even if I manually lower the txlevel setting from 800 down to, say, 300 it still distorts - it's just a quieter distortion. What can cause this?
Here are the tune settings:
[usb] ; name=usb ; devicenum=0 devstr=1-3 rxmixerset=312 txmixaset=800 txmixbset=500 rxvoiceadj=1.259933 rxctcssadj=7.884689 txctcssadj=100 rxsquelchadj=900
Thanks Ken 27021
