Great answer, Patrick, at one time I had complete listing of the NDB beacons in North America, so I would have been able to look it up. Between a partial data on an older computer several years ago, I probably don't have it any more. So if anyone knows where I can an up-to-date listing, I would be very grateful.

When travelling I-25 near Johnson's Corner I can hear a nearby 400 kHz beacon on 800 kHz as I drive past. It was loud enough to overpower semi-local KLDC when they were still on 800 kHz. This only happened on the radio in my 96 Ford Bronco and did not happen on the radio in my 85 Corvette. When I visited the Gillette WY Loran station I could clearly hear the 540,000 watt 100 kHz transmitter on several harmonic frequencies over a considerable distance. On 700 kHz I could hear it clearly over 12 miles away. This was again on my 96 Ford Bronco radio. These were both direct harmonic multiples of the primary frequency and did not have any noticeable effect from the IF frequency in my receiver. However, in some cases the IF frequency or other nearby transmitters can also effect the results. For example, a radio with a 455 kHz IF frequency might translate a 382 or 383 kHz beacon to 1220 kHz (1220 minus 455 divided by 2 equals 382.5 kHz).
