Hi Mike and David,

my latest Hamlib patch should sort this out. The issue was a regression, caused by me, where PTT using RTS or DTR on a serial port, not also used for CAT, was messed up.

Do you have CAT control turned on?

We're still trying to figure out what's causing this.

Hi Allan

I see exactly the same as you with RS232 PTT.

I hadn't monitored the state of the Test PTT button.  As you observe, if this turns red during a receive period then the following transmission has no audio.  If the button does not turn red during a receive period the following transmission is OK.  Watched the behaviour for a number of periods and this seems to be consistent.

    Gentlemen,

    To start with, my system is a Dell 1650, i7 @3.40 GHz, 16GB RAM,
    W10 pro 64bit. I do not use CAT but instead use RTS on COM1 for
    opto-isolated PTT and XFR isolation for audio in and out of the
    sound-card, and have done so without issue since 2006.

    Two problems : -

    1.     I have found with rc2 that occasionally PTT is not working
    at all and when it does there is often no TX audio present either.
    While monitoring 'Radio' under 'Settings' I have noticed when this
    occurs, after a successful transmission about two seconds into the
    _RX_ period the 'Test PTT' button turns red and from that point
    there is no PTT in the following TX period. After a time it
    appears to clear itself and PTT in the following period with or
    without TX audio.

    2.     I am still getting numerous false decodes. Most of these
    contain '/R' and '<.....>'.   I am not using AP.

    Many thanks,

    Allan - VK4QG
