Ah, so true!  I was always very happy with Heathkit designs - exact for that one!

Methinks the term "dog" to be overly complimentary.  I also have a Heathkit 
Tunnel Dipper and note its many problems.  Chief among these is its tendency to 
refuse to oscillate at all in the lower 1/3 of its dial range, and an extremely 
touchy meter seting adjustment.  It really is much better, largely confined to 
use, even, as an absorption wavemeter.
