I am looking for the RIT circuit for a Swan 240 hf transcever that I can build. Can someone please direct me as to were Ican find the circuit?

This might be a bit of a trick, since the Swan used a crystal controlled product detector. You might look at some of the VXO (variable crystal oscillator) circuits in the Handbooks...which allow you to pull a crystal a few kilohertz. However, the last thing a Swan needs is ANOTHER drifty oscillator added to it. http://www.qrz.com/iB_html/non-cgi/emoticons/smile.gif
