It depends on the band, really. At 40m, I’m not likely to reach Europe, but can easily talk to anyone within 400 miles. At 20m I boom onto Spain on 100 watts. I wonder what frequency they used back in those days?
Pretty low—the article says 600m wavelength....but I don’t know if that is what they mean. 600Mhz? in the AM band? very possible as it was before “radio.”
