Lee - A google search for sweep/sweept frequency oscillators/circuits should do it. These things have been around for over half a century, and should be available from surplus houses world wide. For quick look audio testing, all you need to do is drive a solid state oscillator fet frequency control element with a saw tooth oscillator and look at the result on an o-scope. It depends on how fancy you need to get. ----- Original Message ----- From: "ve7fet" <[EMAIL PROTECTED]> To: <Repeater-Builder@yahoogroups.com> Sent: Tuesday, December 30, 2003 11:10 PM Subject: [Repeater-Builder] Plotting Audio Frequency Response
