I don't know what's up with Grant-D/H. However and related to that question ---
Just a couple weeks before Harry Dilling passed away this Spring, he contacted me/
SSCWN to announce his formation of "H.D. Sales" --- a company specializing in supplying the industry with replacement parts for his former company's (D/H) electronics and other components. Harry bought some ad space to make the announcement and told me that Dilling & Dilling and Sun Country CW Systems (both in Texas) would be operating as H.D. Sales distributors.
This is not an "endorsement" per se. But I just gotta say --- that I was especially touched and impressed by Harry's "hanging in there" and his being engaged with the SS industry even tho' he was battling a cancer in its very late stages. You might want to check out Harry Dilling's eulogy in the Summer
SSCWN (in the mail now).
