[Elecraft] [K3] MD3; or MD7; command changes VFO B filter settings

[Frank R. Oppedijk]

Hi all,

I have noticed that when I send an MD3; or MD7; command to my K3 
(which sets the VFO A mode to CW or CW REV respectively), the VFO B 
filter settings (selected filter, filter shift and width) are changed 
to the values that are currently active for VFO A. This happens with 
both 3.77 and 3.79 firmware. VFO B must already be in CW mode for 
this phenomenon to occur.

Can anyone reproduce this?

P.S. Maybe this phenomenon is a side effect of the following. In 
general, the MD command only acts on VFO A. (The MD$ command is the 
equivalent command for VFO B.) However, if VFO A and B are both in CW 
mode and you send a MD7; (CW REV) command to VFO A, *both* VFOs are 
set to CW REV. Apparently, the normal / rev setting applies to the 
whole K3, not just one VFO. This makes sense. However, I wouldn't 
expect *all* VFO A settings to be copied over to VFO B when an MD3; 
or MD7; command is issued.
