AIOC not working with half-duplex on ASL3

AllStarLink

I have set up an ASL3 node on a raspberry pi 4b using an AIOC in half-duplex mode with a UV-21R baofeng radio. I can connect to the parrot node and get a response back but when I connect to another node and respond they do not hear me. I have tried not connecting to any nodes and using it as a repeater, but I still have the issue of it not transmitting. When I key the HT that I am using it triggers the node radio but then the node radio cuts out before I am done transmitting. Any assistance would be greatly appreciated thank you. KF8EMO

I figured out what I was doing wrong, I did not have the volume adjusted correctly. I am having another problem though. I key my HT and the node hears me, but I have to have the node set to parrot mode to be able to hear my transmission threw another radio. My node keeps telling me that I am in full duplex when I have it setup for half-duplex.

How is your node "telling" you it's duplex?

4

When my radio that has the AIOC connected to it keys up the statis in the Supermon council says that it is in full-duplex mode. I am trying to use this as a half-duplex repeater.

Does simpleusb-tune-menu agree that it's stuck in transmit?

I went into the asl-menu and went to option V. It say’s that COS Input is clear, CTCSS Input is off, COS Out clear and PTT out clear. When I key my radio it goes COS Input keyed, CTCSS Input off, COS out keyed and PTT out clear. When I unkey the radio is say’s COS input clear, CTCSS input off, COS out clear and PTT out keyed. So if I understand this correctly it is not in full-duplex mode, but why is it that I cannot get it to repeat what I say? That is how a half-duplex repeater works correct?

So you have duplex=1 and parrotmode=2? And that's inside your [nnnnn](node-main) configuration stanza?

I just tested this and, you are correct, it does not work now....

Please try this (which does work)

  1. In /etc/asterisk/rpt.conf, uncomment 955 = cop,55 where it appears in the configuration
  2. In /etc/asterisk/rpt.conf, change parrotmode=0
  3. Restart Asterisk
  4. Wait a second or two after you hear the startup on the radio
  5. Key up, enter *955 and then immediately speak something without unkeying
  6. Release the PTT
  7. Do you hear your parrot back to you?

Yes I did hear my parrot back to me with this setup. I heard my parrot when I had it set to parrot = 1. My question is with this setup as a repeater with half-duplex shouldn’t you hear it without parrot mode being on? Without parrot mode on I do not get a repeat of my transmission.

No. A simplex node is just that - one way at a time. Network-originating traffic is transmitted out RF or RF-originating traffic is sent over the network. But it's not a "store and repeat" function. That's what parrotmode=2 should be doing.

Thank you that is the answer I was looking for. I thought that I was doing something wrong for it not to work that way. I will try later to see if you have this resolved.

14

What version of ASL3 are you running, and on what hardware are you running it?

15

The latest version and on a raspberry pi 4b.

16

Cool, I'll assume app_rpt 3.6.3 then.

17

I believe so yes. I did not get a chance to check for sure.

18

/usr/bin/asl-show-version

I am at work so I cannot check right now.

I would like to use a second node to retransmit from my other radio, like a repeater.
