Hello Topband propagation experts, I have been messing around with listening to low frequency navigation beacons and wondering how reception on 200 kHz relates to 160 meters. Not sure there is a cor
In some ways it is much better. Remember *200 Meters and Down*? I have two ELF receivers that feed the worldwide blitzortung.org network and lightningmaps.org. It continues to amaze me how far that w

For a given electron density profile, the amount of refraction incurred by an electromagnetic wave is inversely proportional to the square of the frequency. The result of that is the lower the frequ
David, just in case you may want to start into an additional radio hobby, there are a lot of us who chase the NDB stations. I have been amazed at the distance covered by many of these beacons....a go
Hi Dave, Sorry, I don't know the answer(s) to your questions but did want to say, thanks for writing this. I find it very interesting reading. I know VY2ZM conducted some experiments around noon on 1
First thing, 160 meter is NOT the Topband and hasn't been for a number of years. 2200m is the Topband, with 630m in second place, and 160m a distant third. There are two areas of interest in the MF/L
Hello Carl All very interesting! I still see a huge increase in distances as nightfall moves in, but all of the extremely distant stations are picked up at the upper end of the NDB allocation clo
