DX 60 B crystals
« on: December 03, 2022, 01:38:59 PM »

What crystals does the dx60b use. 243? What freq should I look for? Been trying to find a 3.715 do I just ball park the freq and hope for the best? Sorry but I am old and confused. A little dumb also.

 I remember my old DX 60 had 4 crystal sockets, 3 were for FT 243 crystals and the other socket was for the smaller type crystal, I think it was CR 16 size.

Hi,

Yes, a holder type FT-243 labeled 3715 k.c., will contain a crystal used at parallel resonance, with a 32pF circuit capacitance present,
and will oscillate at nearly the labeled frequency. (= DX-60 specs).

You can also use a crystal in the smaller, hermetically sealed HC-6/U holder, with the same characteristics, will also work fine in the DX-60.

Don't apologize for being old.   You had to be smart enough to survive this world.   Been a ham for 59 years now and had a DX60 (not B model) As I recall, mine had only one crystal socket and it was on the front panel.  It fit an FT 243.     Good luck with your fine boat anchor.   You might consider the high end of 40 meter CW portion if that is what you are interested in    73, Jim

I have 2 FT-243 crystals from my Novice days.  3715 and 3704.  I can't guarantee that they are still good, but you can have them if you want them.  The labels have fallen off, but I remember the frequencies.

I ran my Hallicrafters HT-40 for a while with them. 

With these old crystals, there was a vendor who bought the old military crystals and reground them for the ham bands.  These are two crystals from that company.

Send your address to edtheham  at  gmail dot com, and Ill get them to you.
