[R-390] R-390A Calibrator

Tue, 31 Dec 2002 21:34:24 -0500

Hi

The 200 KHz crystal used in the calibrator is an odd cut of crystal. All the
rest of the crystals in the radio are AT cut crystals. The calibrator
crystal is below the low frequency end of the range for an AT cut.

Translated more or less in to English - tough to find anything other than an
AT cut these days. Tough even to find anybody who knows how to set up a saw
to cut the odd cuts.

I'd go for a replacement from Fair Radio or ATC.

    Take Care
