Around '90 i was living in a travel trailer on some property in WA state. The power went out for some days, but i wasn't too inconvenienced;
the trailer heat was propane, and when the trailer battery got low i moved my vehicle up near it and jumpered the car battery to the trailer
and recharged the trailer battery. Anyway the point of this story is that without any AC line noise from appliances or nearby power lines, i
was able to copy a "Lowfer" beacon in the 160 - 190 meter band, i think limited to 1 watt ( input ! ) power, at about 50 miles, on an ordinary
portable multiband radio with no special antenna.
I recall many years ago when i was talking with a U.S. war vet, he was telling me that SOS signals from the Atlantic could sometimes be copied
on the west coast USA.
I want to mention also a QST article of something like 5 years ago on the construction of a vertical for the 630 meters band. There was nothing
radically innovative about this antenna, BUT it did say that attaching the transmitter above the base loading coil made a significant improvement
in field strength. As compared to the more common way which is transmitter feed between base loading coil and ground. I still have the article,
i thought this was so intriguing, with perhaps applications to Part 15 MW broadcast band application, but i cannot dig for the magazine right now
to give the date.
