ok... we'll try this again ... I know I responded to your first post of this message a few days prior but its now gone!
I BELIEVE there is a bug in the software because "Allow TX to change during TX" doesn't seem to work any more. I use to use this and found it to be a good feature - but now with the latest version (2.1.0/64) the red top hat moves but the transmit frequency does not until the next cycle. You can actually 'catch it' if you do this immediately upon transmitting but generally that isn't helpful because I need a second to react to what I'm seeing in the (non) reply. Hopefully this will be reinstated and work as it did previously.
