Hi Ken,<div><br></div><div>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.</div><div><br></div><div>Comment these lines out and restart app_rpt and then you'll be in carrier squelch mode only.</div>
<div><br></div><div>Hope this helps,</div><div><br></div><div>Matt</div><div>G4RKY<br><br><div class="gmail_quote">2010/1/5 Ken <span dir="ltr"><<a href="mailto:ke2n@cs.com">ke2n@cs.com</a>></span><br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
(Asterisk version 0.208)<br>
<br>
Struggling with a new DMK URI and first time use of asterisk, in a test<br>
setup with an HT as the audio source.<br>
<br>
My conclusion is that Asterisk needs to have the CTCSS present no matter<br>
what?<br>
<br>
Settings are:<br>
<br>
carrierfrom=usbinvert<br>
ctcssfrom=no<br>
rxdemod=speaker<br>
txprelim=no<br>
txtoctype=notone ; no - CTCSS tone encoding with no hang time<br>
<br>
It took me a while to figure out that "invert" means that the COR relay is<br>
closed when the signal appears (I would have thought this was not-invert).<br>
<br>
My tests show that the repeater function does not key up unless both the COR<br>
and CTCSS are present. One, or the other, does not do it. This is not what<br>
I expected when I selected "no" for the "ctcssfrom" parameter.<br>
<br>
On the other hand, even when you select 'no" for the "txctcss" it still<br>
transmits a tone, so maybe it is consistent.<br>
<br>
<br>
Second issue: The loudest playback sounds cause the URI to go into<br>
saturation and distort. I may not have calibrated the levels very carefully,<br>
but even if I manually lower the txlevel setting from 800 down to, say, 300<br>
it still distorts - it's just a quieter distortion. What can cause this?<br>
<br>
Here are the tune settings:<br>
<br>
[usb]<br>
; name=usb<br>
; devicenum=0<br>
devstr=1-3<br>
rxmixerset=312<br>
txmixaset=800<br>
txmixbset=500<br>
rxvoiceadj=1.259933<br>
rxctcssadj=7.884689<br>
txctcssadj=100<br>
rxsquelchadj=900<br>
<br>
Thanks<br>
