I sure want to thank you guys for this change! We did some testing on the
nodes here trying to key and talk as fast as we could and experienced zero
clips! We had had so many problems in nets with clipped audio (despite
coaching to key and wait) that I ended up increasing the hang time to 5
seconds just to mask the effect in nets.
This software is so cool and it just keeps getting better with you guys'

This is normal behavior with the simpleusb driver as of the firmware release
at the end of October, 2017 (as of:

full-duplex audio mode. I found that this change improved performance,
mainly reducing audio latency and reducing or stopping the occurrence of
"chopped off" first syllables when the TX is first enabled. I haven't
noticed any negative side effects (????), so far. I run all my systems in
full-duplex, at this point.
If for some reason you need the original half-duplex-when-idle behavior, you
can revert to the old mode by setting duplex=0 for the node stanza in the
