• 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:

WatnNY,

From the "New Memphis ARTCC frequency" thread

AirScan, where do you get the information to make the maps? They are awesome!
The sector number and boundary info. I get directly from the respective Center or if that doesn't work through a FOIA request. I try to update it every 3-5 years or if I hear of any big changes.

The actual frequency and sector configuration I keep updated from personal monitoring (I travel a lot) or from using various internet radio sources like LiveATC, Broadcastify, GlobalTuners, etc.

Accurate information is not always provided from the FAA, although some Centers are better than others, so reports from others that routinely monitor high altitude airspace are also very helpful.

Attached below is what I have for the Knoxville area. Maybe you can help me out ? It's been a few months since I checked the frequencies in that area. Do you notice any changes or do they still look correct ? I'm also wondering about ZTL37-ZTL39 configuration, I know the sectors above ZTL36-ZTL40 combine when it's slow and I assume 37/39 do as well but have not been able to confirm it.

I have complete coverage of North America, but so far only high altitude VHF frequencies, still working on low altitude and UHF. If anyone else is interested in a high altitude VHF chart covering their area and is able to provide feedback on accuracy or info on new frequencies and sector configuration etc. post your location here and I would be happy to attach a chart of the area here in this thread.

Any other updates from anywhere always appreciated if you can post them to the forum.

You can also buy charts from Jeppesen. They can be pricey and I don't know how current they actually are when new ones are released.

Jeppesen high altitude charts, like the government charts don't show individual sector boundaries and only some select high altitude frequencies, many are missing. Just as an example the latest Jeppesen chart is missing 8 confirmed high altitude frequencies for Cleveland Center.

You can access high altitude charts from Skyvector (free).

If you are just looking for frequencies the best reference I've found so far is the RR database here.
