[Elecraft] K3 Beta 4.42 and LP Bridge

[Larry Phipps]

I have added support for K3 beta v4.42 to LP-Bridge and posted v0.9.994 
update on my LP-Bridge page at http://www.telepostinc.com/LPB.html

I tested this with the latest HRD 4.1 beta and it seems to be solid. I 
also added the SMH command to the "speed governed" list of commands to 
minimize the chance of this command overloading the K3 serial buffer. 
You should switch back to LP-Bridge and not use LPB2, because LPB2 does 
not limit the polling rate of SMH as LP-Bridge does. In general, K3 
users should use LP-Bridge. LPB2 was mainly designed to support other 
radios.
