Title: Sinad Meter
Post by: Paul M0BSW on December 12, 2016, 01:14:21 PM

I've been looking for a simple sinad meter circuit, as the proper thing is way to expensive, although I've googled it, no luck.
Is there such a circuit, it would be nice to be able to measure sinad on the receivers I build, with out using a pc program.

Paul, I still plan on building one from scratch using the Motorola design. Will see if I can post the schematics for you.

No problem Paul. I think this circuit is a bit easier to build over the Sinnader 3 version. I plan on building one also just to show folks how to do it. I want to make 2 boards, One through hole and one for smt.

Should be a fun project for you.

Hi Buddy, I must admit I bit the bullet and built some smd, and love it now, at 62 a microscope is a must :)

I hear that Paul. I cannot function with my microscopes.
