[chirp_users] using two different radios together

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

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
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.
