Having recently acquired a HP 5065A with clock I decided to put a battery in
it. My choice is 5000 mA Lithium Ion. Having in the past very good experience
with a Florida vendor, was first choice. Sadly he is going out of business.

I made a mistake in the previous post we use the ICS 570 with very good results
in many applications. So it was easy to test. This has to be the easiest and
lowest cost circuit. Start with an AC14 ST, followed by a divide by 5. I used
part of a HC390 but a LS 90 will do. Take the 2 MHz output fe
We use the ICS527 for many applications easy to get 80 or 160 MHz. in non
critical applications I use an AC14. Have a small board, 14 and ISC only if

I started using WWVB in 1970 in Houston working for TI using a Tracor Omega

and I modified quite a few for their Cal Labs in the US and Europe. Got a award
and could keep all the extras. In those days TI was still in
