Crystal Tester
« on: April 18, 2014, 07:26:06 AM »
This  has become a very useful device, which can be be found on Alan W2AEW You tube channel, it's a crystal checker,it's hooked up to your scope and frequency counter. I built this in probably my favourite method Manhattan or island style.
So here is my chance to say "Thanks Alan". This is going in a box & belongs on the bench , I'm using a Ali or maybe a ABS box, couple of grippers to connect to the Crystal, and a couple of BNC's for scope and Freq counter. I'll post a final picture shortly.

I should make myself one as well, to test the giant collection of crystals i have, all with odd frequencies on them.

Well here it is boxed and working on the bench, another item ticked off.
Yes you should Sean, especially if you want to build a X-Tal ladder line filter, I've been able to match 10 up very close to 0.002, which should make the job easier, when I have the RF sweeper up and running.

This looks like a fun and handy thing to build---I have a small jar of mystery crystals, so...

... that does mean I need to go and get a frequency counter first, mind you
