BTW. What type of radio do you have.

I was using different pafamaters for each radio type, but for the second version, I just used the DM1801 settings as it seemed to need the most compensation

I have a Radioddity GD-77 and flashed it with the appropriate file from the link above.

What happens with the first version I sent, are you sure it stutters ?

Can you retest it perhaps with a real QSO.

I will test with Parrot, but 10 people already tested the first version and it was OK for them.

But perhaps there may be a bug on the first transmission after turning on the radio.

I made many changes to the firmware to optimise the code etc and this fix is actually a byproduct of those changes, rather than an attempt to fix the ticking problem

Yes, I'm quite sure for it as I tried several QSOs after testing out with a parrot.

We can arrange a SKED to test it out, just name the timing which suits you.

Is it skipping DMR frames so that there is only audio ever 2nd frame?

If so.. I think there is a buffering problem in the firmware which I need to fix.

I emailed you another version to test, which has some changes to reduce current consumption on Rx.

Tested it out and emailed both videos back to you.

The second version of yesterday does behave better. The first one and the one you attached cause the loss of syllables.
