[Boatanchors] WANTED: FT-243 Crystal for 7160 khz

[Bry Carling]

I have come acroiss a good number of operators lately running ancient radio equipment 
around 7055 - 7065 kHz and some operate that way, "a little off." Probably not as far off as in 
thue novice days., but it is fun to hear an occasional bit of "yoop," or a signal from a guy who 
makes a very high freq audio (or very low) from his carrier appear!

There is another good pocket of this style operation up around 7110 - 7125 kHz these days 
also. When you get on the air and start operating it is quite amazing. I find it easier to contatc 
guys running older tube gear now in 2013 than I did ten years ago!
