Nice.
What receiving setup do you typically use?
I think my best graveyard catch has to be...
1240 KALY Albuquerque, NM (now off the air) received in El Cajon, CA, using a Panasonic RQ-SW20 and Select-A-Tenna. The local co-channel KSON (now KNSN), whose transmitter is west of me and close enough so I don't get the rumble that's typical of that frequency when there are multiple stations fighting it out, WAS, believe it or not, ON the air! (They were just broadcasting an unmodulated carrier at the time, enabling me to hear what was then the Albuquerque, NM Radio Disney outlet in the background.)
From my location, KALY was 617 miles away at a 71.3° E-NE (clockwise from N) heading. KNSN is 11 miles away, at a heading of 245.9° W-SW (clockwise from N).
If conditions were right... I wonder how far a graveyard could get out until the signal is just no longer there.... And, by conditions being right, I mean NO man-made noise, NO other stations on the air, using the absolute BEST radio and antenna known to exist, naturally-occuring noise at a minimum, etc. How far would such a station (on groundwave, or on skywave) get out, until it just is no longer to possibly detect said station, even if it changes mode to an extremely narrowband QRSS CW or whatever is currently the most efficient mode? If the FCC did what I think would be the right thing and changed co-channel interference protections so that the aforementioned contour was not allowed to overlap (at least for the non-graveyards), I wonder how many stations might fit on each channel?
(But, then, there would also need to be something done about man-made RF noise (the type that's not intended to transmit RF energy, but does by nature of its operation). Personally I'd like to see that limited to, say, 192dB below the natural atmospheric noise floor, measured at the inside surface of the enclosure of the device.
