RE: original post:

I do not believe this was fixed in the last release or two.   It appears that the tx audio buffer is filling while in receive, and a few hundred milliseconds of that buffer is being sent at the initial time of transmission. It appears that the tx audio buffer needs to be gated and/or delayed a few hundred milliseconds once PTT is activated.

For example, if I am listening to a QSO with the speakers, and they are obviously loud enough to open the audio gating of my tx audio chain, when I first key up, stations are reporting a noise burst at the beginning of my transmission. Using a headset is NOT a solution..........

Yes, I believe we fixed this issue in 1.4.
