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

[Ted Roycraft]

Alan,

Thanks for your note.  I do have all the players, the K3, P3, and 
LP-Bridge, set up for 38400 baud so I don't think that's the problem.  
I'll experiment more tonight with different parameters in LP-Bridge to 
see if I can see what sensitivities there are.  I'll let you know.

Thanks,
73, Ted, W2ZK
