[WT-support] Wrong Frequency logged on second radio contacts

[Bjorn LB1GB]

Hi Bob,

We ditched the DX Doubler SO2Rxlat solution and bought a MK2R+, before
even really trying out the DXD SO2rxlat thingy(just one contest).
Still we have second radio contacts with wrong frequency.

SE5E also reported this in the October archives.

(at this time we used DXD)

We are running Win XP. I must say that we never saw this problem while
running Writelog.

The only USB driver used now must be the one between MK2R+ and PC.
