PRO-43 Discriminator Tap
 

Hi,

I seem to remember an online site that explained, step-by-step, the
procedure to tap off the PRO-43 discriminator.

Can anyone help me with this particular process?


Thank You!

Mike

Yes, the Autumn 2005 issue of 2600 on page 13 has some fun with the
PRO-83 that you are looking for. I think there's also a discriminator
tap modification that was posted on the Internet by Gary Hahn, KB9UKD[1].

"A discriminator is a circuit that voice-band filters the base-band audio
coming out of the FM detector, so that the audio coming out of the speaker
and headphone jack sounds good."

Hope this helps?! This will void your warranty on the scanner.

Whoever you're quoting should first have learned what a discriminator
does. That's not it.

You know who I am quoting, Al!

Nope.

A discriminator is the part of an FM receiver that extracts the desired
signal from an incoming FM wave by changing frequency variations into
amplitude variations.

Yep.
