No. I've used them both with an HW-16, and in fact the HG-10 is NOT  
"VASTLY" more stable than a VF-1. It depends on WHICH VF-1 and 
WHICH HG-10.

A properly built (or re-built) VF-1 will be at least as stable as a properly  
built (or rebuilt) HG-10, sometimes more. 

Also, for either one, a lot depends on the choice of oscillator tube. I had  
to go through 4 or 5 6CH8s in order to get my HG-10B to be as stable,  
and to key as well as, my re-built VF-1. 

Of course, I also had to "hand select" a 6AU6 for the VF-1 to get it to  
operate at its best capability. 

When I changed the 6AU6 to a 6AH6 and dropped the regulated  
voltage from 150 VDC to 108 VDC as suggested by Glen Zook, that  
made the VF-1 even more stable. 

The VF-1 is a good VFO...as is the HG-10. 

I use a re-built VF-1 as my main VFO with my HW-16 for CW net and  
general operating.  

I had one of our net members tell me the other day that my rig sounded  
like a new rice-box. I wasn't sure that I liked the comparison, but I  
understood that he meant it as a compliment.
