[Heath] AR-3 - vernier

[Glen Zook]

I must be lucky in that both my AR-2 and AR-3 the variable capacitors are working correctly.  However, above the broadcast band, even with the reduction, it is not easy tuning in any particular station.  That is where the bandspread dial comes into play.  Using the bandspread, it is easy to tune in any particular station even on the highest frequency band.

Well, after repeatedly applying lighter fluid, interspersed with some PB Blaster once in a while, my "good" AR-3's main tuning inner shaft can be rotated inside the outer shaft with considerable difficulty....but at least I appear to be making some progress.
Tuning is still 1:1, but I am hopeful...
Trying to "center" the tuning of any station, even on the BC band, is very difficult. 6:1 tuning rate would certainly help.
