Strange unearthly feedback noise been there on this freq every day this week! 5040khz USB.

What time are you listening? I ask because Radio Habana Cuba is on that frequency every day 2200z to 0700z in AM mode.

Hi
Those kind of signals do not need an enigma designator to me... but it's a different story..
It's 5042 LSB and i think it's close to FRA, ITA or SPA
It is just a TX site re-broadcasting its own signal, received remotely on his associated RX site (linked via microwave links or whatever)
I saw the noise produced on the LSB xmit last night, but tonight EU short skip is very bad, i almost not copying it at all from here
It re-broadcasts the 5040 AM carrier with a way higher signal strength, that prooves it's definitaly LSB (enhancing 2000Hz tone)

Hi linkz
That's really interesting, I'll wait until R Habana is on and have a listen. You're right they aren't enigma stuff.
To answer your question MDK2, I'm usually listening UK day or evenings so outside those hours :)
Cheers

These kinds of signals were just given an ENIGMA designator as an oddity signal. Just an easy way to say something and everyone understand what was meant. XM is the feedback sometimes called "backwards music" or "whales", XWP is CODAR radar, XSL is the Japanese Slot Machine, etc. Most of these were assigned before the real source of a signal was known, so it was an oddity until the source was figured out. As I understand it the "X" designators were originally meant to be used that way, but the practice of assigning those seems to have fallen by the wayside. The last one I am aware of was XUP in 2010.
