Snow effect

M0RVB

It's snowing fairly heavily here today and I wondered what effect, if any this would have on my QO100 reception. Very little it seems. There is no loss of signal strength when viewing the lower beacon, but the noise floor has raised a little.

There's not a great deal on the dish but then it's pretty much vertical. There is a wedge of snow at the bottom of the POTY rain cover.

Clearing the snow off made no noticeable difference to the signal. It's snowing less now and still nothing noticeable. I need to compare with a clear sky... which we had the next morning. There is actually very little difference, the noise floor appears better but it's very hard to say by how much and indeed if this is even real. The signal strength appears very slightly better. Without proper measuring methods it seems the snow and ice made hardly any difference.

Wet string effect

My bit of wet string in the loft, or rather, my fan dipole has been doing quite well of late, albeit only on FT8 and FT4. By fan dipole you are no doubt thinking of a dipole made up of several, i.e. more than two, dipoles cut to various bands and all terminated on one coax. Well, yes, but I only ever got round to making it for 20m and 6m. But even there it has been doing well these past few weeks with all of Europe in easy reach and forays into USA as far as the west coast, Canada, South America, the top of Africa and the Middle East, plus occasional contacts in Turkey, Russia, Oman and Kazakhstan. Not too bad at all given the 20m wires are far from straight, being bent at the ends to fit and not straight horizontally either. I mean it's sort of an inverted vee with a level bit in the middle and does seem fairly omnidirectional, probably by accident but hey. It will tune on all bands from 40m to 6m thanks to the YT-1200. Since I passed the Intermediate I've set the FT450D to 30W, the maximum for the tuner,…
