[Dx4win] Radio time outs with DX4WIN, LP_Bridge, K3 win XP PRO

[Randy Farmer]

I have the same setup and I also experience occasional dropouts of radio 
control with the K3. I don't remember ever being in front of the radio 
when it happened, so I don't know exactly how often it happens or if 
it's correlated to anything in particular. I have observed that 
sometimes when VFO A and VFO B are on different bands the bandmap will 
momentarily jump to the VFO B band and then back to the normal VFO A 
band. This may be a clue.

My interface to the K3 is through a microHAM MK2R+ two-radio box, with 
the radio run from the primary (virtual) CAT port and LP-Bridge run from 
the (virtual) 2nd CAT port. Since the radio isn't a LP-Bridge client, I 
suspect the problem is somewhere in the DX4WIN-K3 interface rather than 
in LP-Bridge. I used a microHAM microKeyer II that runs the same Router 
software with a FT-1000D and an Icom 746 for a couple of years and don't 
recall seeing any dropouts with either of those radios. My money's on 
some sort of subtle K3 software interface problem.
