[ARC5] Test set help

[Mike Feher]

I may be wrong - but - to the best of my recollection, these worked on
harmonics and not on the fundamental frequency to be measured. I still
probably have a few around. Regards - Mike

Hello John and thanks,

On "e" I find the freq meter (described below).  Item ID is :  110548908304
The point of interest is "Day 44" - because this is the same day the "glide
bomb" appeared.  Mr. Mike, is this of interest.

Beyond this, it seems that someone sold a warehouse of gear, and it's
dribbling 
onto the market.  There may be a gem lurking in there ....
