    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:

This is a link to some interesting pictures of charts that show range comparisons of different radio types compared to amateur radio. I thought it was interesting. I do not agree with everything it says. What do you guys think of these? Is this what they teach new hams these days or what? I have never seen these before.

Without an explanation of how this information was arrived at, it's meaningless. Looks neat, but still meaningless.

Anytime you see such a simplified interpretation of radio propagation with no attempt made to reconcile the innumerable variables involved in such comparisons, it's a pretty safe bet that the details are wrong.

I think the only thing I would accept with these charts is the generalities made implying that higher power will talk further. But even that's not always so simple.
