Dear 1.3.9 tester dudes,
T/R times have got to be the best we have ever seen.
It looks as good as one of the early 0.n.n releases.
I tried CW on 40M with these audio/DSP buffers with
these results:
Audio DSP
------------
2048 2048 ok
2048 1024 ok
2048 512 ok
2048 256 ok
2048 128 ok
2048 64 ok
1024 2048 ok
1024 1024 slow flutter
1024 512 faster flutter
1024 256 very fast flutter
the following with pops and crackles
moving IF width or shift causes audio to glitch
512 2048 ok
512 1024 slow flutter
512 512 fast flutter
512 128 very fast flutter
the following with pops and crackles
moving IF width or shift causes audio to glitch
256 2048 ok
256 1024 flutter so bad RX unusable
256 512 fast flutter
256 256 very fast flutter
the DELAY setting on the CW window does not work.
The new T/R is super fast!
