[Elecraft] K3 Beta 4.42 and LP Bridge

[Larry Phipps]

Hi Sam. Sorry for the delay in response. I get the reflector in digest 
mode, so I don't see postings sometimes for hours. I subscribe to so 
many reflectors on which 90% of the traffic is superfluous, that I am 
forced to use digest mode to keep the traffic at an acceptable level. A 
direct email or posting to the LP-PAN reflector would be faster.

You need to have the SDR app set to poll slightly slower than LP-Bridge. 
This is because polling from the SDR is passed through when it's 
running, and then some additional commands like SMH are added in 
LP-Bridge. This takes some additional time, and hence the slower polling 
rate in the SDR. I didn't play around much with the minimums in each 
program to see what differential is required, but the 250ms LPB / 300ms 
SDR that I normally use works fine here.
