Gentleman,
it doesn't work unfortunately. PTT is always "OFF - OFF" when both K3
are shutdown. No matter if the computer is running prior to the K3 or
vice versa.
I asked another ham friend nearby with two upgraded K3's, the same
issue. Could anybody else please try this?

The K3s does this to avoid the extraneous keying due to activity on the
USB serial port while the computer is booting up. You can put the K3s
into USB.SAFE mode like this:
"Safe" mode disables PTT or keying transmissions until the K3S receives
a command via the USB interface, such as a read of the rig's VFO
frequency. To turn on safe mode, go into CONFIG:PTT-KEY and tap 1 to
select USB.SAFE. Exit the menu and turn the radio off/on. Applications
that use PTT-KEY but don't send commands will require UNSAFE mode (the
default). In this case, be sure to turn the PC on before the K3S.
Cheers and 73,

I pimped both of my K3 with the new KIO3B boards in order to avoid that
nasty sound card cabeling etc. It works fine via USB but one strange
thing happens with both radios.
I have to set "PTT-KEY" to RTS-DTR every time after powering down and
power up the radio again. Both K3 forget the setting "RTS-DTR" each and
every time. No matter what the computer or the operating system is,
RTS-DTR always switches to "OFF-OFF" when the radio goes OFF. What am I
doing wrong?
