I can send it to you, BUT..
It is totally un-supported. ?I am not sure I understand it at this point.
It is a two part system, one in the rx, one in the tx, talking over a one wire bus.
I posted the basics of the system a while back.
Let me know if you really want the code.
BTW, I really like the way it¡¯s working for me now.

Hi Gary
Where can I find the source code for the FS-5B version?

You want 16MHz..? Like I said in a previous post, it MAY be possible to change the Arduino
to 20MHz but you don't really want the hassle.
There are a lot of 20MHz TCXOs available but 16MHz is rare.

Yes some have a hole that allows access to fine tuning.
it can be supplied for the frequency of 16 mHz or it is necessary to upgrade the frequency of the Nano from 16 to 20 mHz.

Gilles,
The main reason is because I have a better solution for my project.? See photo, the small silver device in the lower left corner under the 25K trimpot.
There hasn't been much interest in the frequency counter is another reason.
BUT, the one you show might work.? The problem is it might be stable but it is not adjustable to exactly 16.0000000MHz so your count will still not
be correct.? BUT, see that little white dot on the main oscillator??? That MIGHT be a sticker and under it might be a trimmer!?? MIGHT.
There are some chinese vendors on ebay that sell just that part (which may be all that is needed) and one or two indicated they could make them 16MHz.
