[Hallicrafters] HT37 problems solved (?)

[Oliver J. Dragon]

Joe,

If it hasn't been mentioned already, I recall using the S-meter in my Drake 
2-B rather than the HT-37 meter when nulling carrier. It's been 45 years or 
so but I think putting the '37 in MOX and receiving on my un-muted '2B did 
the trick. Might have been a more sensitive setup than pulling the "meter 
sensitivity" control on the '37. Time fades memory however, so I may not be 
recalling things quite correctly.

Good luck with the setup. Wish I still had mine.

Ollie.
