ASL3 and Pi3 and USBradio mode

1

New repeater and I seem unable to run USBradio mode on ASL3. It was working fine on Hamvoip, but it falls over on ASL3. I'm inquiring if anyone else has experience the following and here are the specifics:

  • I've tried two different URI's, Repeater Builder RIM and DMK.
  • Both work great in SimpleUSB mode, but I need USBradio to run CTCSS enc/dec
  • When I switch to USBRadio, I set COS to USB as I'm still using the repeater's squelch. CTCSS is DSP.
  • The hardware COS LED on the URI's work great as far as I/O from the repeater, and like I say, this worked great in SimpleUSB, however when running the "V" view option, the COS shows Keyed for a few milliseconds upon a valid signal, then reads Clear (the COS hardware LED does stay solid with the signal present). The CTCSS from DSP stays keyed as it should. Of course the transmitter can't stay keyed as the COS has "dropped out".
  • If I disable the transmitter in software via COP3, this all works fine.
  • I know for a fact it's not RF getting back into the Pi, as I killed that separately and COS was still flaking out.
  • I then switched COS from USB to DSP, and same issue. Flaky COS keyed/clear toggle. So this is a computer issue. I've tried two different ASL3 builds, manual and appliance, same result. Two different Pi3's same issue.
  • Regretfully, this has been at the remote repeater site and much time wasted, two days dealing with this anomoly.
  • Has anyone else experienced this? Is this a resource issue perhaps, running ASL3 on a Pi3B+ trying to run USBradio? COS behavior was fine running Hamvoip USBradio, Hamvoip suffers from less than stellar audio in that mode, hence the desire to run ASL3.

have you tried running cos or dsp inverted?

Well, the URI logic dose not change between the 2 channel drivers...

You are not reusing an old config file are you ?

Can you post your usbradio.conf for a looksie

Makes no difference, like I say, the COS logic is correct via the hardware LED on the URI's and works fine in SimpleUSB.

Mike, these are clean installs of ASL3, What I was really hoping was to find someone running ASL3 in usbradio mode on a pi3B+ to see if they have the same anomoly.
usbradio.conf (Main Node template is section is default, except for the CTCSS tones of course)

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;;;;;;;;;;;;;;; Configure your nodes here ;;;;;;;;;;;;;;;;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;
; Note: there is no need to duplicate entire settings. Only
; place settings that are different than the template.
;
; Note: the device string is automatically found when the
; USB setting "devstr=" is empty.
;
; Note: the interface "tune" settings will be added to the
; per-node settings (below).

devstr = 1-1.3:1.0
rxmixerset = 188
txmixaset = 500
txmixbset = 500

rxctcssadj = 6.822986
txctcssadj = 650
rxsquelchadj = 988
fever = 1

Could you manually verify this.

It's the only URI on the node, via asl-find-sound, and of course if that was not correct nothing would work.

To answer your specific question about RPi 3B+, ASL3 and usbradio, I have several running this combination. All are fully DSP on RX - COS and PL (multi) decode.

Also running on RPi 4 and Dell Wyse 3040.

@k5jr I believe that answers my question. TY
Update: I have solved this issue. For whatever reason, usbradio.conf has added a line in the default configuration that doesn't exist in simpleusb.conf, and that is "duplex = 1", which is half duplex. This setting does not exist in radio-tune-menu either. Why it's ever there I don't know because that mode is set in rpt.conf. So manually changing that to "duplex = 2" in usbradio.conf allowed the repeater COS setting to stay keyed. I will be reporting that oversight as a bug on github.
