[Test-Equipment] FS: Heath IM4180 FM deviation meter

[Brooke Clarke]

Hi George:

Another FM radio test is SINAD or "SIgnal Noise And Distortion" how to make 
that measurement is on my web page: http://www.prc68.com/I/MTE.shtml#Test
I haven't come up with a simple way to measure deviation, but maybe someone 
here has?

Have Fun,
