I'm seeing an odd problem, but it might be difficult to describe.

I have a Raspberry Pi Zero running the latest software and DireWolf 1.4.E. ?But it has also done this with version 1.3.

I am running this as a digipeater only without any internet.

When the transmitter is turned on (PTT from GPIO Pin) normally the audio/data is sent almost instantly.

Sometimes there is a long delay between PTT and sending any audio. ?This long delay is sometimes 5 seconds, and I've even heard close to 10 seconds of carrier only, no audio, then the data burst.

You might think that it is waiting for the frequency to be clear, but it has already turned on the PTT and is transmitting, just no audio or data yet.

I'm sure this isn't enough information yet to figure this out, so where do I start looking?

Thanks, Arnold
