• 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:

    Anyone successful in ridding this burst on ht1250s?

    I am aware of the repeaters turn off code, pl settings, and lower end motorola repeaters. This issue is common when newer radios equipped with a active key loaded ucm or mace key transmitting in analog clear using post mdc data will emit a nasty burst if mdc is not muted and in any case muted...
