• 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:

149.0750 and 150.3750--Part of NSWC Dahlgren LTR System?

From my location in Fredericksburg, I can barely hear these two frequencies. They are both giving off the characteristic ten-second blip of LTR system frequencies. I also heard brief voice inversion on 150.3750. The only LTR system with voice inversion that I know of in this area is the one at Naval Surface Warfare Center Dahlgren. The weakness of the signals from Fredericksburg would suggest that these frequencies may be originating from there.

Would someone who lives closer to Dahlgren give these frequencies a listen, and see if the signal is stronger? You don't necessarily have to live in King George County; you could probably hear them well from the Northern Neck and even Southern Maryland.
