• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

Does the skip occur at a predictable time, or does it just happen whenever it feels like it? I'm new to the whole skip thing and I wanted to know if it was predictable so I knew when to listen to the scanner.

It all depends on the weather, sunspots and other factors. I'm not 100% sure, but, I think there is some information in the wiki area of the site. Also, there are some VERY intelligent people on here about skip/tropo. Also, look through some of the other posts in this forum. It should help ya out as well.

Predicting Skip

For ducting skip check this site:

http://www.dxinfocentre.com/tropo.html

This site shows when the MUF (maximum usable frequency) climbs into the low band:

Consider the Yahoo skip group:

Sporodic E has no exact predictability. Add early warning frequencies to your scanner. This list is a good start:

Check this link out. It is a very good demonstration of how propagation is effected by the atmosphere. How skip works and such. Once you watch this flash demo and read through, you should have a better understanding of SKIP and how it happens.

THIS ONE IS AWESOME CHECK IT OUT:
