[ICOM] 706 MKII - CW filter on SSB

[Buck]

Thanks, Clark

I tried it and you are correct.  

I was playing with the rig during the contest this afternoon and discovered
that on CW the rig hears both sides of a signal but it has a pretty wide
area that is zero beat.  If a signal isn't strong, I don't know its there,
but if it is the right strength, I won't hear it but it desensitizes the
signal I am listening to.  

My discovery today is that I need to get a good CW filter!

Thanks

Hi Buck -

I think you are noticing the different carrier insertion for CW.  This 
is, in effect, moving the IF shift control far to one side.  Look at 
the little diagram on the 706 when you touch the IF shift in the CWR, 
remember that position, go back to SSB and make it look the same.  It 
should now sound the same but you'll be in SSB.  I don't have the 706, 
I have the 703, and that little graph appears for IF shift....  if you 
don't have it, just go to SSB and fiddle with the IF shift, it should 
do the same for you.
