Title: RCA BTA 1R2 Crystal replacement. Answer found
Post by: VE2VMS on January 04, 2018, 12:50:51 PM
Looking To replace the crystals in ovens with 1880 and 1885 kcs.  Naturally, the xmtr will be retuned.  Does anyone knows a supplier of crystals?

The FT243 crystal holder fits perfectly in the oven.  So, I ordered a 1885 kcs xtal from AF4K.

Don't forget that Bomar Crystals is again making single custom crystals again. I've been happy with the ones I got from them recently. Not cheap but exact replacements.

I bought crystals for both old GE MASTRII Repeater and Motorola MICOR Repeater. $50 each crystal, ICM was $25 many, many years ago. HC-18 for the GE and both HC-16 & HC-6 for the Motorola. About 30 day delivery time. Just email or call, they're very helpful. After ICM quit making crystals Bomar decided to get back into making customs again. I'm glad they did!
