I had a National NCX3 for a short while that I tuned the same way. Except the power supply hum was loud enough that I didn't have to put my ear to it. Or maybe my ears were young enough. Sure wouldn't mind having another of those, or better, an NCX5. 

Dave mentioned the Swan 270. I have one of those, got it last year, but no idea if it transmits. Receives fine though. I have a D104, but again, no idea if it still works or if the crystal element's gone or what. So, two variables.
