Max,

Since you said that you are very new to programming radios, I would use a transitive method https://en.wikipedia.org/wiki/Transitive_relation of troubleshooting the issue you are having.

I would get the frequency-tone-offset info on a local repeater that is open to the public, and program one of the two radios to tune into that repeater.

Once I'm able to hear the repeater on the radio, I would see if I can key-up from the same radio and raise the repeater.

Next I would do the same from the second radio.

When radio-1 is able to send and receive from the repeater & radio-2 is also able to send & receive from the same repeater, then radio-1 & radio-2 will be able to talk to each other directly if you swap the send & receive frequencies on one of the radios, while making sure that you are using the same DCS https://en.wikipedia.org/wiki/Squelch#DCS or CTCSS https://en.wikipedia.org/wiki/Continuous_Tone-Coded_Squelch_System settings on both.

Based on my limited experience, currently, when you transmit from the ATR-22 & the EVX-531's receive lights up, the receiver is expecting a specific DCS https://en.wikipedia.org/wiki/Squelch#DCS or CTCSS https://en.wikipedia.org/wiki/Continuous_Tone-Coded_Squelch_System tone that it is not seeing.

The ATR-22 is either not transmitting any tone or not the one that the EVX is expecting.

It will be interesting to hear what you find.

Hello,

I'm trying to get two different radios to talk to one another and I'm running into an issue that I think is due to me never having programmed a radio before! Specifically I'm trying to integrate an Amcrest ATR-22 radio with a Vertex Standard EVX-531. I'm using the CE142 software for programming the 531s and CHIRP for the ATR-22. When I transmit from the ATR-22 the green receiving light comes on the EVX-531 but there's no audio. When I transmit from the 531s there's no receiving light on the ATR.

Does anyone have any idea what I'm missing here? I'd really appreciate the help.

Thank you!
