[Fwd: Re: Problems with SSB Audio]

[Paul Wilton]

Bob,
Thanks for the advice but I don't have RFC15 installed.  Mine is an A
series K2 and when I did the A to B mods a few years ago, the "do you
need RFC15" test proved negative so I didn't install it.

I could, of course, try installing it now - provided I can find it!

I went through this, too, but then when I added the PLL temperature  
compensation mod, I found it was a necessary change. Otherwise, my  
rig hand much LESS temperature stability.
