Im sure there will be people who say FT8 is just progress. But some psychologists divide people according to whether their preferred mode of experience is auditory, visual or kinesthetic (touch). I t
Yes, a pennant antenna with a pre-amp could be a tremendous help. I live in a densely populated suburb where everyone (including us) has all the latest digital noisemakers. Without that set-up, the l
Carol Regarding the use of ferrite chokes to kill common-mode noise coming in on the transmission line, look on the internet for A Ham's Guide to RFI, Ferrites, Baluns, and Audio Interfacing, by Jim
Anyone who doesn't want WWV and its sister stations to close down needs to SPEAK UP NOW. Sometimes bureaucrats and politicians faced with demands to shrink their budgets propose things for eliminatio
WWV has been broadcasting an outdated propagation report for several days, giving the solar flux as of September 18 and K Index as of 1200 on September 19. THIS MAY BE A TEST TO SEE IF ANYONE IS LIST
I think in the last few days the lightning has died down a lot. Hurricane Michael seems to have swept a lot of other weather systems away, at least along the U.S. East Coast. The Intellicast map of l
David -- Suggest you take a look at the attached paper by Jim Brown. I live in a fairly dense suburb where every house (including mine) has all the latest RF noise-makers. Following Brown's suggestio
BTW, note that if the line is coiled on the tarp in a figure-8 shape, it won't tangle when you fire it. Same trick works when you pack up the headset wire to your smart phone -- when you put it away,
You may also want to check out the SAL-12, -20 or -30 antennas from Array Solutions. My yard is pretty small, but I was able to put up a SAL-12, and I love it. (I do mostly 49-, 60- and 90-meter SWBC
I can't speak to all the technical details of this discussion, but I can say that I've had a very good experience with the SAL-12, despite having very difficult terrain. My SAL is partly over concret
On the NOAA website "Space Weather Enthusiasts," they show, among other things, the solar wind speed and magnetic field details. Reports of great conditions on 160 seem to be most common when the sol
Back in the early 60s, NASA launched a couple of satellites named Echo I and Echo II that were essentially huge reflecting balloons. You could tune to WWV on 20 MHz at a time of day when that was abo

Not sure how much height you need for a K9AY loop. I've used 16-foot Shakespeare fiberglass poles for various antenna supports. Amazon has 10, 13, 16 and 20-foot versions. (Search for Shakespeare fib
After you walk in that area, go over your clothes with one of those sticky-tape clothes rollers. That should pick up any tiny ticks that have latched on. _________________ Searchable Archives: http:/
I certainly remember when I was a kid that we would have deep fades on a.m. BC stations coming from 20 miles away, plus or minus a few. But that was at night. Are you doing your tests in the daytime?
Overall, I have to say that 160M propagation is still somewhat mysterious, and we should be careful about judging too quickly what others describe as their experience. We're like the three blind men
I can't speak to Czech law, but in American law there is a wise maxim: "If you want equity, you must do equity." That is, if you come to court complaining that someone's actions were so unfair that t
Thanks. Very helpful. One question: The attachment says: "The coloured dot within the black square, is an indicator of solar wind density, and is yellow when density exceeds 10 particles per cubic cm
