[R-390] Capehart made R-390A Serial #312 -- 2nd crystal oscillator frequency list

[Thomas Hoyer]

 I think they look pretty good and would proceed with the overall radio alignment. After that if you find any bands that you can not get reasonable dial accuracy by using the zero adjust then consider looking at changing out the crystal. The only time I've run into the need to change a crystal out was when it was dead. My sample size is only a couple dozen 390A's so maybe I have just been lucky.

  All freqs are low. Worst ones are marked red and orange. Y415 (15.5 MHz) is
brand new, manufactured by German firm Quarztechnik Daun GmbH. This is my
first attempt to post an email attachment to the R-390 list. Hope it will
work. Question: how do I deal with all these (100%) crystals off frequency?
Need to replace all crystals? That would definitely make my R-390A too
expensive. Again: advice welcome.  Tnx in advance.  - Karsten --
