Vernier Dials
Perfect control for air variable capacitors!

Surface mounting for 1/4" shafts. Planetary drive, ratio approximately
4 to 1. Dial Calibrated 180°. Ideal for QRP receivers, transmitters, or tuners.

These are getting to be a scare item. Our overseas manufacturer will be doing one more run of these for us in May 2007. After that they will no longer be available. As far as we know, there is no other MFG. building these. The price will be going up on all three styles May 1st 2007. We anticipate a supply of maybe 1 year from the May 1st date.
At this time, we must say, Sorry, but  dealer quantities will be limited.
