[TenTec] Century 22 calibrator

[Mike Bryce]

boys and girls…

I’ve been working on a calibrator for the century 22. It’s a drop in replacement for the original.
Here is a link to some photos and ‘scope traces at 100, 50 and 25 kHz.

Like the original, this one will be able to pulse its output so you can find it on a busy band. If you notice, there’s a lot of missing parts. The pulse circuit didn’t work correctly (I screwed up the artwork) so a another batch of (corrected!!) pcbs will be made and tested.
