I love the sound of regens on AM and was only thinking the other day (inspired by your TenBox efforts) about a TRF IF application.<br /><br />Look forward to your design. <br /><br />David.

Sitting in the back of class, I used it to listen to the cricket scores, wrote them on slips of paper, and passed them around the classroom. Eventually, it was confiscated by the deputy head, and all that saved me from punishment was the fact that he was fascinated by what I had built. Good times!<br /><br />Dave<br />AA7EEAnonymousnoreply@blogger.com
