Thanks for this info Dave.
Of course I have these x-tals; they also been used regulary for 80m fox
hunting TX's.
Biggest problem however, is to divide by 13........
I do not have to much schematics about dividers.

I found another solution, hi
I took an 4.433MHz X-tal and tuned it down to 4406kHz......
That divided by 16 will give me the 275.4kHz I need to drive the rest of the
circuit.

Any schematics/links about how to divide by 13 are welcome.

I'll be on this afternoon 14-15ut on 136.550kHz +/- 50Hz with CW 8wpm beacon
mode.

Maybe, one of these days my signal might show up around 137.7 in QRSS
3......
