Re: [Drakelist] RV-4C VFO slipping

[Garey Barrell]

Usually a result of the hard rubber "doughnut" behind the dial plate 
hardening with age.  You can try removing the doughnut and roughening 
the "ends" with sandpaper to give a better grip.  Some have used 
automotive "heater hose" to replace the original.  There is a good 
article on this at

Anyone know of a fix for the VFO slipping?

I have taken the knob off and made sure it is all tight against the 
bushing when reattaching, but it does slip (just slightly) during 
regular movement of the dial.
