    McCoy SSB Crystal Filters (1963) -- But Apparently NOT the Real (Lew) McCoy

    Posted: 30 Dec 2021 01:55 AM PST http://soldersmoke.blogspot.com/2021/12/mccoy-ssb-crystal-filters-1963-but.html

     Last month we were talking about this company.  Someone thought it was run by Lew McCoy of ARRL Homebrew fame, but it now appears that our Lew McCoy
    was not involved in the company. Note how they provide TWO carrier oscillator/BFO crystals for each 9 MHz filter, one for USB, the other for LSB. They were pricey too:  In 2021 dollars, that Golden Guardian would
    cost $390. Thanks to the K9YA
