Poor conditions (noob)
« on: January 13, 2020, 0402 UTC »
Hey,

I'm not a noob to radio, but propagation (other than the more obvious non-planetary/solar noise stuff) has not been something I really understand very well. I do understand the solar cycles to some extent, but I am curious about the more frequent changes in propagation that can be seen on a daily or weekly basis. What is the biggest determining factor in that?

I noticed the last couple days that the propagation has been some of the worst I've seen since I started listening about a year and a half ago. What is causing this and when is it likely to clear up?

Not an expert here, but the sun's output varies from day to day, even minute to minute. That's why the K and A indices change.

Why the effects of that difference in solar output varies from region to region, even in the same latitude, I wouldn't know.

The auroral radio zone can vary also, which is why northern latitudes have different prop than the more southerly latitudes.

The best part is when things are great, sigs are strong and steady, and then they're gone, like someone flipped a switch.

Unfortunately we are on the down side of things, but all you can do is receive or transceive as much as you can. I can remember the days like most people on the forum of amazing contacts, but hey it is what it is and there are still catches to be had here and there. I get a bit depressed personally if I think about it on a daily basis, so I try not to. With that being said I do respect those who follow on a regular basis. It's people like you that post updates for people like me with their head in the sand like an Ostrich.

Conditions have been wonderful on the lower bands, Lately I've been receiving pirates from Greece on MW. And it is nice to not have nearly continuous solar flares and CMEs, wrecking the geomagnetic field for days or weeks.

Solar minimum isn't a bug, it's a feature.  :)

The hell it is, 40 and 80 were dead last night. Must be my timing.

Agreed.  Poor conditions on higher frequencies doesn't mean that there isn't fun to be had elsewhere.  Take our operation for example; when conditions on 43M started taking a nose dive, we modified out operating practices.  We are using more power than before, but not by any large magnitude.  The real difference was made by going down to 4 MHz during the winter months, and 6.3 MHz during the summer, where the MUF was more usable, and with less interference.

I also remember a number of nights closer to the peak where I would be heading out, only to find out after I was setup that we had a CME and conditions were poor.  Mimimum is not a bad thing!

This is why I miss " '73 Magazine". Tomas Hood could set up a prop chart a month in advance that was nearly flawless.

Depending on your respective perspective, that is also the bad news  ???

I suppose it makes for easier listening when everyone is forced to operate below 10MHz or so.

80 meters is horrible for using right now..what happened?
