Chris, Bob tried with a diagram and it did not come thru. Another reply gave excellent web site for simple transistor circuits.
I'll try: Using an NPN such as 2N3904 or 2N2222 1. ground emitter 2. from collector connect 4.7k res to +voltage (5, 12, etc) 3. connect 20k res to base and other end of 20k use as COR/COS input. The inverted output will be off the collector where the 4.7k and collector connect. 73, ron, n9ee/r >From: chris_campton <[EMAIL PROTECTED]> >Date: 2008/07/09 Wed AM 10:04:09 EDT >To: [email protected] >Subject: [Repeater-Builder] COR REVERSE SENSE > >Anyone have a circuit diagram to reverse a cor from high to low to low >to high? > > > Ron Wright, N9EE 727-376-6575 MICRO COMPUTER CONCEPTS Owner 146.64 repeater Tampa Bay, FL No tone, all are welcome.
