Working with USBRadio with a radio that does not have COS. I almost have it total correct, but it keeps node keyed and times out connected nodes. When I look at RX Squelch level, it says current signal strength is 998. What am I missing? Since squelch is not broken, I would expect the value to be zero. If I unplug audio from radio its the same. Can you inverter squelch signal? Radio is a Alinco DR-CS25T.
Os 6.12.75+rpt-rpi-v8
Asterisk 22.7.0+as13-3.7.1-1.deb12
the "Carrier from" setting sets the logical True/False for COS.
easily tested with squelch open and squelch closed
look for "Carrier from" values usb and usbinvert
There is no cos from radio, so dsp must be used?
if dsp only, then i'm quite sure there should be no squelch used because of the way FM demodulators behave in the absence of any signal (they go to maximum output level on noise)
is there a helper script for setting up the USBRadio interface?
what does it look like? (what variables are you given to adjust?)
The pi produces a carrier when carrier from is set to dsp. I can even unplug radio from uri and still has carrier. Does the same thing if vox is selected. But does functions with ptt and audio both ways, but times out connected nodes.
i'm only now getting familiar with USBRadio versus SimpleUSB
have you experimented with carrierfrom = vox and using CTCSS from a test radio (not the radio connected to the interface - Alinco, right?)
oh, and if you are making value changes to variables, do so at the very bottom of usbradio.conf, if you didn't know already
I tried every setting…lol. Pi is producing a carrier without audio, but everything works until it times out connected nodes. I really think usbradio does not work like advertised.
Carrier from = no
Ctcss from = no
Pi keys radio, radio does not key pi
No timeout
Carrier from = dsp or vox
Ctcss from = no
Radio keys pi, pi does not key radio
No timeout
Carrier from = dsp
Ctcss from = dsp
Radio keys pi, pi does not key radio
System timeout
Carrier from = dsp
Ctcss from = no
Linktolink = yes
Radio key pi, pi keys radio and audio and ptt work for both.
System timeout, constant carrier no audii without ptt
I spent hours on DR-CS25T. I done every configuration for USBRadio. I can get it passing PTT and audio both ways, but it has a sub carrier that times out connected nodes. Against my better judgement, I took radio apart. Without schematics there is no way to find a cos line. There is an led that goes red on inbound and green on out bound. No way to know which leads are what when apart. I will run four wire wrap wires out in hopes I get at least 3.3 volts for COS. Dog with a bone!
You can not use speaker audio with dsp, needs to be flat unsquelch audio. When you get flat audio In the radio tune menu run the set squelch level
.. and part of the puzzle may be to enable CTCSS encode and decode (aka TX pl tone and tone squelch) on the interface radio (Alinco).
usbradio.conf by default is expecting you to use CTCSS tone 100.0 or 91.5
oh i see now - with reference to the manual, there is no "dataport" on that radio. this will make your ASL integration task more difficult, as you're going to have to figure out where to tap audio before any filtering or bypass what filtering there is (for the speaker output)
It does. Many people use it.
What's keeping the PTT keyed? ASL itself will not generate any carrier. If you're getting a carrier transmission with no audio, it means your radio is being keyed by PTT but there's no transmitted audio being generated likely because your PTT is broken. It could be you need a pull-up or pull-down resistor. Or maybe a transistor because the audio interface can't sink the signal enough. Another issue could be that the systems are not all sharing the ground properly? Doing what your doing is pretty difficult because the radio isn't meant to really be used the way you're trying to use it.
There is nothing from radio hanging ptt. Its generated by the image in dsp mode. I can even unplug uri and ptt is still being generated. I appreciate the comments and will re-visit it. I really would like to get USBradio working. I tapped off the led light that indicates inbound signal and used it for cos. I switched to simpleusb and added the led cos wire. It works perfect. I also have linktolink on and duplex is at zero, just like with USBRadio. I must not understand dsp settings. Vox should of worked, but acted like dsp.
