I'm currently using the Trial version of P2A with the Microsoft voices David, Crystal and Zira set as ATC and Copilot.  When one of the voices speaks within P2A I get a horrible musical 'jingle' sound for two or three seconds sounding at the same time  - is this something added to the trial version or have I got a setting wrong somewhere as its driving me nuts.  The only thing I could see is the trial lasts for 10 days, not any irritating noises added ?

There's a speech recognized tone that you can turn on/off or change the tone.  It is set on the Btns tab of Config under the PTT HotKey.

Many thanks Dave, that was the problem.  I found the 'Com Radio Swap Tone' and that was off but didn't see the ' Speech Recognition Tone' in the Btns tab.
