[Elecraft] Strange problem when switching modes from VFO A to B

I have VFO A programmed for CW on each band, VFO B programmed for SSB 
(makes no difference which sideband ).  Power up the K3 on VFO A then 
switch over to VFO B and the signal generated is extremely distorted and 
sounds like it is being transmitted via a very narrow filter.  To 
correct this problem simply switch the mode from L or USB to CW and back 
again to L or USB.  Audio is then restored to normal.  I have the 
filters programmed correctly, the 2.7KHz filter is used for transmit.  I 
am using the ESSB mode with a 4 KHz filter.  This problem is independent 
of band.

I mentioned this to Gary who passed it onto Lyle and who was unable to 
make it happen.  I am using firmware 2.38 DSP 1.92.  I am waiting for an 
update which will fix the turn on audio spike before updating.

Any suggestions ?  It is just a nuisance getting a report of who is that 
calling!!!
