Have heard a number of beacons on longwave, including one (rarely) on 524kHz Mount Carmel, IL. It's about 250 miles away and according to
http://www.airnav.com/navaids/, it has an output power of 25 watts. A number of Voice NDB's have been taken off the air in the last couple of years, in my area these were 242 kHz Milwaukee and 350 kHz Chicago. So by now most of the NDB's are only transmitting a Morse Code identifier, the old Voice NDB's were broadcasting weather information and special announcements regarding nearby airports and airfields - almost all of that has gone to VHF, UHF, Satellite or the internet. I have picked up the NDB from Dixon, NC on 198 - DIW - and it has heterodyned with what I believe was the BBC on 198 kHz - no big deal, DIW has a power of 2kW - most NDB's are 100 watts or less!

I have heard faint LW signals with a Sony ICF-SW7600GR with its internal ferrite antenna when heterodynes were coming in on Medium Wave 603, 692, 747, 837, 873, 1134, 1269, etc., I would then switch to LW since the MW band was coming in so well, I thought that I would try LW since it's an adjacent frequency range. I could receive signals on LW that were not beacons, but I could not hear these clearly enough to identify them, never got above the atmospheric noise level. These signals were at the frequencies listed for Europe, such as 162, 189, 198, 207, 252, but the carrier never became strong enough to hear audio.
I also have an Icom IC-R75 with a long wire, however, I am not far enough away from the high powered MW stations in the Chicago area to avoid AM broadcast station images...I will need to get/build a preselector, possibly filters, a box loop and/or an amplified antenna in order to hear these LW stations. LW stations have been heard in the interior of the U.S. (i.e. the midwest), it's just that the propagation has to be very strong in order to overcome the signal path over land.
And be advised that more and more of these stations are being decommissioned (silenced) due to aging equipment and soaring electricity costs, and broadcasters in those countries perform listener surveys like they do here, and these surveys are showing that listeners prefer FM to MW or LW, so it's a matter of time before many of these stations (our catches!) will be no more. So, try to hear 'em in the next couple of years - particularly in the late fall, winter and early spring months.
