[Elecraft] Problem connecting LP_Bridge through the P3 to the K3

[Brian Alsop]

Even with the latest version of LP-BRIDGE (9.8), I continue to 
experience some rig time outs.  All occur during periods of transmitting 
where one does not drop back to RX during that period.  Direct connect 
without LP-BRIDGE shows none of these.  They happen even with the K3 
throttled back to 5 W or less so RFI isn't the cause.

There certainly appear to be some timing issues with LP-BRIDGE/K3.

It occurs with no P3, two different rigs and two different logging programs.

Just what RS232 activity is permitted between the rig and LP-BRIDGE 
during transmit?  Are there blackout periods where the K3 will not 
respond to polls?

The nature of the time out is that the logging program doesn't think the 
K3 is attached any more.
