[App_rpt-users] new simplex node, can't connect in transceive mode

Sun Jan 11 02:48:04 UTC 2015

Elden,

 As a newcomer I would suggest just using simpleusb. In most cases there is no real advantage to using usbradio and in many it actually degrades the audio. So don't feel like you are missing out on something, enjoy your new node.  Many use simpleusb and it works perfectly fine. If you were using the BBB I would only suggest simpleusb.

Yes, switching to simpleusb seemed to fix the problem of not being able to interpret a DTMF key of "3". But I'd kinda like to figure out how to use the normal usbradio.conf rather than the simpleusb. I cannot for the life of me figure out how to get it to interpret a '3'. I tried all sorts of various level settings. I did try a different radio to send the DTMF with, it had the same issue. Could not get a '3' to register.

Also, according to my instructions I did set the carrierfrom=usb and ctcssfrom=no.

Elden,

 I thought you said you were using simpleusb. If so ctcss is not done in software. It is done in the radio and the cos or squelch line out of the radio will follow the ctcss that the radio receives. There are two input bits in simpleusb - carrierfrom  and ctcssfrom. They both are just bits you read to determine there is a received signal. It does not matter which one you use but we generally use the carrierfrom which corresponds to pin 8 on the DMK URI. Pin 8 would be connected to the radio COS detect. 

So if you are using the DMK URI you connect pin 8 to the radio cos detect - made true by PL into the radio - and then you set the carrierfrom=   either  usb      or usbinvert     depending on the direction the incoming signal goes in when the rx gets carrier.  If it goes low then usbinvert and if it goes high then usb.

The ctcssfrom would be set to no meaning it is ignored.

I'm afraid I don't know how to control the CTCSS filtering. I thought CTCSS controlled the interaction between radios. I totally don't get all the references to it in the config files or why asterisk has anything to do with that. But there is obviously a lot I don't know.

I would add one thing to what Doug said. Make sure you have CTCSS filtering. PL really messes with TT decoding.

Elden,

Before you do anything make sure the rig you are transmitting the DTMF from is doing it correctly and the TX levels are good. Substitute another rig if you can.

 This is almost always caused by equalization or level problems. 

First of all make sure your levels are correct. If they are then:

Allstar can use either flat (non pre/deemphasized) or pre/deemphasized audio. Depending on what radio you are using and how you have it connected would determine how to set this in the configuration file. If you are using simpleusb take the audio from the pre/deemphasized points. This can get a little complicated for a beginner so if you need more explanation let me know.

The bottom line is if you are pre/deemphasizing in the radio then you don't want to do it again in the SW.

Found a clue on this...
It appears that asterisk is not able to properly interpret a '3' DTMF tone in my particular setup. Below is part of my log, where I keyed 123456789 123 123. You will see that there are no threes. Wonder what is up with that?[Jan  9 19:32:23] NOTICE[25376] chan_usbradio.c: Got DTMF char 1 duration 319 ms[Jan  9 19:32:24] NOTICE[25376] chan_usbradio.c: Got DTMF char 2 duration 320 ms[Jan  9 19:32:26] NOTICE[25376] chan_usbradio.c: Got DTMF char 4 duration 278 ms[Jan  9 19:32:26] NOTICE[25376] chan_usbradio.c: Got DTMF char 5 duration 276 ms[Jan  9 19:32:27] NOTICE[25376] chan_usbradio.c: Got DTMF char 6 duration 235 ms[Jan  9 19:32:28] NOTICE[25376] chan_usbradio.c: Got DTMF char 7 duration 277 ms[Jan  9 19:32:29] NOTICE[25376] chan_usbradio.c: Got DTMF char 8 duration 256 ms[Jan  9 19:32:30] NOTICE[25376] chan_usbradio.c: Got DTMF char 9 duration 256 ms[Jan  9 19:32:44] NOTICE[25376] chan_usbradio.c: Got DTMF char 1 duration 213 ms[Jan  9 19:32:44] NOTICE[25376] chan_usbradio.c: Got DTMF char 2 duration 213 ms[Jan  9 19:32:46] NOTICE[25376] chan_usbradio.c: Got DTMF char 1 duration 276 ms[Jan  9 19:32:46] NOTICE[25376] chan_usbradio.c: Got DTMF char 2 duration 255 ms

Greetings,
I just setup a new simplex node (first time). I'm using the URI and a cable that I bought that should work with my Yaesu FT-7900. I did the radio tuning. I don't have a service monitor, so I did the best I could.
The problem I'm having is... I can make outbound connections to systems in monitor mode, but I seem to be unable to connect in transceive mode. When I try to connect in monitor mode, I get instant feedback saying I'm connected. When I try to connect in transceive mode, I get nothing at all.
