Homebrew crystals for transmitters
Hello, All:
Rumor has it that QST featured an article in a January/1930 or January/1935 issue on the subject of homebrew transmitter crystals - how cut, lap, and mount them. If anyone has QST on CDROM for those years, I'd sure appreciate if you could take a look. Remove XXX's and ZZZ's if you wish to reply directly, and thanks. Pete AC7ZL |

Look -- out there, through that big thing that looks like an aluminum-framed monitor! There's trees! There's a sky! There's smelly old cars putting things into the box on the road by my driveway! It's it's -- the real world! Dang! I forgot about that. Suitably chastised, the respondent offers: If you're interested send me your address, I'll bleach out a few pages worth of my precious vintage ink (you'll see the irony of that when you get the copies), and send you the stuff. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com |

Pete AC7ZL Pete, I have my Dad's grinding stuff, but don't do it. One thing to keep in mind, and I don't know the details, but remember that the crystal activity is effected by the edges. Grinding the edges is one of the more esoteric aspects. -- Steve N, K,9;d, c. i My email has no u's. |

Ah yes..the good 'ol days of grinding FT-243 Xtals with toothpaste(or comet)to go up, and writing on the blank with #2 pencil lead to take them down a few Kilocycles....Eddie |
