DTMF Codes not working but can use allmon3 to connect

AllStarLink
1

I just set up the latest release of Allstarlink on a RPi4.

I WAS having problems with using the node to talk to other users and with using DTMF commands to connect to another node. Getting a static IP alleviated most of my problem. I can now connect/disconnect/monitor other nodes but I cannot use DTMF to do that.

I set receive audio using simple usb tune and it is correct now, I used node 55553 to check it and got "your audio is good" after making some changes to the RA-35m as well as software tuning.

The radio is a tyt TH-9000D.

I am pretty sure there is some configuration that was not addressed when I used the step-by-step allstar appliance setup instructions because if I try to send a connection via my HT, e.g. *355553, I get 'macro not found"..

Any advice would be appreciated.

While running asterisk -rvvvv, enter your DTMF codes from your radio and see if they all successfully decode. The 3 might be missing.

I just did it. *,1,4,5,7,8,9,0 decoded but 2,3 and 6 did not.

Also, audio level on the 55553 parrot were all over the place for DTMF. Audio was "pretty good" for just talking.

So that's a sign your receive audio is (probably) too loud. Try backing it down little by little in the tune system until they all decode.

Check both your levels and your emphasis curve.
If the repeater is flat, then pre-emphasis, de-emphasis and PL filter should all be enabled in simpleusb. usbradio defaults to rxdemod flat and prelimiting. Then it's a case of checking your rx gain.

Not sure how to check the curve, but I am beginning to suspect that it's this cheap Baofeng radio. I am going to try again with the D750; it should have a decent DTMF.

Thanks again for helping, Patrick. Audio levels are fine on 55553 but as I said earlier, the numerals 2, 3 and 6 do not decode using the CLI and "rvvv". In addition, audio levels using the parrot are either very low or very high when I press DTMF keys, so might be the cheap radio.

An audio-level check on one of the parrots is all well and good but if you're over-driving your audio such that DTMF isn't decoding, you audio isn't adjusted right regardless of what a parrot says.

Ok. What do you suggest? I did use the simple usb tune application and had the peaks just reaching 5k, so I'm not sure where to go now.

Just turn the rx level down a bit, try your DTMF, repeat until they all decode.
