I used carrierfrom=dsp and ctcssfrom=dsp I am not sure why folks are having serious issues with that, but it works very well, and I have zero issues with it. I do crude signal testing with it, and even when the signal from the node radio is choppy, I can still command the node to do things. I would say the biggest hurdle for getting DSP to work correctly is using the radio-tune-menu with a service monitor. This is to ensure the input and output audio audio levels are correctly set, and the DSP functions can understand the different audio freqs coming to it. I do not use a COR/COS and the node does all the CTCSS stuff. Just TX/RX audio, and PTT connections are made to the node radio. for the radio that requires 5V or active HIGH, use the K0KN PLRI interface. Very simple: a couple resistors and transistors. No need to waste time modifying a USB sound FOB, which is difficult to do because of the size of components one would be working with. ~Benjamin, KB9LFZ On Wed, 2013-07-03 at 14:48 -0600, Joshua Hintze wrote:
Thanks Ben for the quick feedback. I think I might have figured it out. It turns out my COR signal might not necessarily be the best COR signal. It looks like the signal goes high on BOTH RX and TX. This is probably causing asterisk to think its receiving when its sending getting into a nice infinite loop.
I'm going to try an AND gate with the PTT so that PTT has to be high (i.e. NOT TX) and speaker mute (my COR) has to be high for a true COR output on RX.
In the meantime I tried carrierfrom=vox but it didn't really seem to work. Anybody get this working properly?
Thanks,
Josh

sounds to me you are using a simplex node.
In your simpleusb.conf or usbradio.conf, ensure duplex=0, and not duplex=1. This is different from duplex= in rpt.conf
I had the same symptoms when I first setup my node.
Also, make sure you use the radio-tune-menu with a service monitor or some other methods to make sure your have good, clean audio being transmitted over the internet and over your node radio.

Hello,
It is my first posting on here. I have ALMOST gotten the ACID installation working. I'm using the URI interfaced to ACID and to my radio. The asterisk can properly key the radio and its working just fine with that. I can also connect to the node with iaxRpt directly with no problem and transmit OUT of my radio.
However I am having some issues when my radio receives communication in that as soon as I get my first radio RX, asterisk will then play a tone out of the URI into the radio over and over again at about a one second interval. In the asterisk terminal it just keeps repeating:
-- Hungup 'Zap/pseudo-1726358622'
-- Hungup 'Zap/pseudo-1774817359'
-- Hungup 'Zap/pseudo-691532115'
-- Hungup 'Zap/pseudo-81389311'
-- Hungup 'Zap/pseudo-465154784'
-- Hungup 'Zap/pseudo-627058532'
-- Hungup 'Zap/pseudo-1656870264'
-- Hungup 'Zap/pseudo-1671691803'
-- Hungup 'Zap/pseudo-50274194'
forever keeping my radio always keyed.
I have the COR from the radio going into the URI. I do not plan on using CTCSS and have tried tying it to ground as well as tying it to the COR as well. My usbradio.conf has the following:
carrierfrom=usb
ctcssfrom=no
I have tried also ctcssfrom=usb as well.
Any help would be appreciated.
Thanks,
Josh
