Ken, a friend of mine had a MccKay Dymec receiver with variable bandwidth and the External McKay antenna. Living in NY he tried listening to WSM (650) which was first adjacent to WNBC (660). He was unsuccesful due to the "splash" from WNBC and neither station sounded all that good. In those years I had built a true wide band AM radio, a crystal radio using a diode and a tuning capacitor. WABC was far and away the strongest station at my QTH and while it did contan highs above the standard 7.5 Khz most radios of the time afforded, it's processing sounded rediculous on that wide band radio and every time we had thunderstorms, as we often do in the summer, the resulting static was annoying. Of course at that time we didn't have AM stereo broadcasts in NY and when we finally did thanks to the man with the wrath not knowing when to quit, it became a joke with only Sony manufacturing a multi system radio and basically died off. Like it or not AM is going the way of CW (and I love code. My top speed at one time was 35 wpm and it was basically the only HF work I did). That was in the 80's. It's 2011 and the old 20 wpm test I took down on Varick street to pas my extra is no longer required. CW is no longer seen as an essential. AM radio is going the same way, but for a very few facilities. Just look at what's happening in Canada and much of the advanced world where broadcasters are turning in their AM licenses.
