[JMS] I have a Millen VFO !!

[Don Buska]

Hi Sherrill,

The Swing Arm is a means of fine tuning used on both Millen VFO's.  On 
80 meters it might change the VFO frequency by a few KC's  and more as 
you go down band-by-band.  It's connected to a small value variable 
cap.  Instead of using a standard knob Millen attached it at a 90 degree 
angle to the front and attached a arm to it.

If you look at the 90700 VFO at 
http://www.isquare.com/millen/eqpicts/90700.html it attached on the left 
side of the VFO box and you can see a good view of it on the lower 
picture.  On the 90711 VFO it's on the right side of the dial slide-rule 
window, see http://www.isquare.com/millen/eqpicts/90711.html or check 
out the better pictures at W0YVA's personnel site 
http://www.isquare.com/personal_pages/millenvfo.htm .

It works great to zerobeat a signal or to compensate for any drift.  
Although the MIllen VFO's are probably one of the most stable VFO's made.
