I can confirm the OP's report. I have exactly the same problem with

keying. The rig keys up but no audio after band change tune or tx.
tx restores mostly.

Answers to the questions - and / or comments:
Do you Stop monitoring and Halt Tx
before a band change?
> No, I didn't need to stop monitoring in prior
versions. I never change bands during a TX so the 2nd part of
that question doesn't apply.
> The RFI question doesn't apply because I'm never transmitting
when this happens. The PTT method I use is CAT. The radio goes
into TX with no issues, but there's just no audio.
R: So after changing the band you have
received a full timeslot to spot somebody and double-clicked his
call, I assume. And your Tx has gone to transmit at the
beginning of next appropriate TX cycle, but no audio. After
noting that you use “halt Tx” and “Enable Tx” and still no
audio. Or did I missed something? Or do you have “Double-click
on call sets Tx enable” unticked and you use “Enable Tx” to
>Your assumption is correct. I'm waiting for a callsign
to show up - after a decode - than double clicking on it to
initiate a response, and yes during the beginning of an
appropriate TX cycle. The second part of your question is no
longer valid, as I've discovered that a "halt/enable" cycle does
restore audio during TX.
Does this “no audio after band change”
happen also, when you try to send a CQ in the next available Tx
period after band change? I assume that there is no confusion
about “Tx even/1st “ and which time-slot is used for
> I don't know, because I always listen for other
stations and respond after a band change. I understand the "TX
even/1st" concept. I've been using this program for well over a
year and haven't had any issues until 2.3.0.
I have assumed that audio is sent at the
same time as CAT has commanded PTT on. By the way which PTT
method you are using and which rig we are talking about? We have
some unknown issue in your system.
>As I have answered or provided before, I am using CAT
control to command PTT. The rig is an ICOM 7300, I now know of at
least 3 other 7300 owners with the same issue, as well as Yaesu
and other ICOM models. Others i have contacted agree that nothing
changed in their setup except to upgrade to 2.3.0. They can all
restore the transmitted audio by doing a "halt/enable" cycle.
I appreciate your interest and support - I hope my answers are
