[600MRG] ebay variometer?

[Edward R Cole]

I ordered two of these 0.6 rpm motors but only need one for tuning.

If someone has a 3rpm motor and would like to swap, let me know.  I 
could use the faster motor for polarity rotator on one of my eme 
projects.  This would let me rotate 90-degrees in 6-seconds.

Currently I have two taps on my base loading coil but installing a 
variometer would be handier.  I see about two turn change in 
resonance between summer and winter and bandwidth is only 5-KHz.

I did not get my inverted-L repaired before snowfall so may not get 
it up until April.
