Any offerings regarding the longest distance MW, AM broadcast that you ever got ??? Talk Radio U.K., 1053 and 1089KHz. (both frequencies heard) Exact distance is hard to estimate, as they have several high-powered transmitters on both frequencies and there's no way to know which transmitters I was hearing. (probably the sum of several) I've heard a loud 1KHz heterodyne against 1520 WWKB, which almost certainly came from Saudi Arabia, but with no audio heard I'm not claiming it. Going the other direction, my best Western DX would be 690 CBU and 1130 CKWX, both Vancouver, Canada. CBU heard battling with flea-powered KOAQ in western Nebraska and a French-language station in Saskatchewan, with the 50KW powerhouse in Montreal off the air. CKWX is actually heard surprisingly often here on the big antenna. Mine, here in NJ, has been: 580 KMJ in Fresno, CA. It's a 50KW station that I have been able to hear a few times during exceptional MW conditions. I had to use SSB, NB, several tweaks to the pbt and my "Frankenstein" antenna, but I was able to hear the station ID. I kinda hate to throw water on the fire, but are you SURE you heard KMJ? California is pretty tough even from here, let alone from New Jersey. Most East Coast DXers report 640 KFI, 680 KNBR (the most reliable California signal here), and 1070 KNX. I don't think I've ever seen a report of KMJ from east of the Rockies. KMJ is only 50KW during the day (they reduce to 5KW at sunset) and is directional during the day. (my educated guess is they protect Boise and Topeka. The latter null is in a line to your location.) I won't say it's *impossible* you heard KMJ but I do think it's rather unlikely. My guess is you heard some other station (maybe WHP Harrisburg?) carrying the same network as KMJ and mentioning the California station. Keep at it. You *will* hear California soon enough! -- Doug Smith W9WI Pleasant View (Nashville), TN EM66 http://www.w9wi.com |

My guess is you heard some other station (maybe WHP Harrisburg?) carrying the same network as KMJ and mentioning the California station. No question about it. It was KMJ. I've actually heard it three times. The first time I heard it was by accident while I was MW DX'ing in SSB. I could tell it was either a powerful distant transmitter or a weaker one that was not so far away. When it was audible, I heard the station ID as KMJ. I returned to it several other times when MW conditions were good, and I was able to hear it on two other occasions. All three times I was able to hear it, including the first time, were between 9 and 10pm est. The last time I heard it was a month ago. The signal went from inaudible noise to barely audible to perfectly audible a few times over a period of about three minutes before it went out completely. I can understand why you would question that one though. The first time I heard it, I didn't believe it myself. That's why I went back to it so many times :-) The next time we have prime MW conditions, I'll make a wav file recording of it if I can get it again and put it up on my web page. -- Respectfully, Michael Home Page: http://md_dxing.tripod.com/ Northern NJ R75 w/DSP, Kiwa agc/sync & audio mods G5RV & 200ft longwire w/ICE-180 MFJ-1048 preselector SoundBlstr Live PC card w/five piece Cambridge speakers & full software mixer/eq.
