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. 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 No, the good _really_ 'ol days of taking a chunk of quartz, whacking pieces off of it with a mud saw, hand lapping the saw marks off and mounting it in a home-made holder. That namby-pamby FT-243 wasn't invented until just before WW-II. The same magazine has an article about the blind ham who built his own equipment. Soldering by feel. There were giants in those days... -- Tim Wescott Wescott Design Services http://www.wescottdesign.com |
