I don't know.  That's why I'm asking...  :-)

There are folks using converted CB radios, and folks using HTX-100's,  
that seem to stay on frequency all the time.  Granted, none of them  
are using an LC VFO, but they aren't rock-bound either.  I've been  
using converted crystal-based CB transmitters for 6 or 7 years and  
they've worked, but never looked or sounded as nice as the K1.

If it's an impossible goal for the K1, I'll accept that.

Thanks again and 73 de
