[Elecraft] New problem switching frequencies and modes with K3 FW 4.05

[Don Wilhelm]

  Dave,

Is there any chance that you are running PowerSDR/IF v 1.10.3.4?  It 
would cause exactly that kind of frequency shift - even when the buttons 
on the K3 were used.  The amount of shift was the CW pitch that was set 
in PowerSDR/IF.
Upgrade to v1.10.3.5 to fix it.

73,

For example, if VFO A is set on 14.008.00 CW-R and I see a SSB spot for 14200.00, when I double click on the spot, the K3 changes to 14.199.42 instead of 14.200.00.  Then if I click on a spot to go back to 14.008.00 the K3 changes to 14.008.58.  In both instances I have to double click on the spot a second time to get it to change to the correct frequency.  Note that the difference is +/- 0.58 kHz.  The problem also occurs when switching from SSB to RTTY.  It also seems to be occurring using both normal CW and CW-R.
