[MRCA] CR-1 crystals for an RT53B/TRC-7 RT

[Jason WA6BBQ]

Look into qrp-labs.com ProgRock2.  It’s actually a synthesizer that runs
off of 5 volts.

I modified a TRC-77 with two of them,  and it works super, easily gives me
6 transmit and 6 receive frequencies , and I can change the T/R frequencies
at will.

It will take a little work to adapt to your application, but still easier
and vastly cheaper than unobtainium xtals.

Unfortunately, it’s a British company that ships from somewhere in Turkey,
so you will be paying some tariffs and related fees.
