The 7031 signal is being widely heard. It's not strong here in
Montana, however. I'll be interested to see if it's still there in
the AM. I've been hearing it for at least ten hours.
Is it -strong- at anyone's location?

Hello,
In CONFIG menu, i've modified, by error, the PTT RLS parameter;
old value was ??? and now i've set to 002.
I don't find on my K3 (#1212) manual rev C1 the use of
this parameter. I know i could reset to the previous
parameter setting, but i would prefer to know the
significance of PTT RLS.
Hello,
Found ok in release notes !

PTT RLS is the delay between you releasing the PTT and the K3 changing
from TX to RX. It is used in ARQ data modes such as Amtor or Pactor to
allow time to clear the data from the TX (DSP introduces delays in the
K3 IF). The values are in milliseconds, typically set to 012 for using
an SCS PTC

Similar behavior here with K3 #202. However it only happens when in VOX
