Here are results of an attempt to gather information on utility and BC signals which are interfering with free broadcasters on 48 meter band from time to time. I didn't adopt the goal to mention ALL the stations between 6200 and 6500 kHz in this table, here are mostly that signals, which are currently active and audible good and regularly in Europe.
Some of the stations can be find in public frequency bases, but all the lists are incomplete, obsolete or have numerous errors, so I managed to find or verify some of their locations using TDoA. The new TDoA technique, available on Kiwi SDRs network, lets to find approximate coordinates of radio signal sources by times of arrival difference for several used SDRs. However, one have to remember: TDoA can be wrong sometimes.
UNIDs, presumed locations and inexact frequencies are written by italics. Any corrections and additions are greatly welcome.

Thank you, Kris, for the comment!
DeleteThanks for this - really interesting. In fact, I have found out that one of these is only a few miles away from my QTH.
ReplyDeleteYou are welcome. Thank you for the comment! This list actually needs some updates, because utility stations are changing frequencies at times.
