It would be great if you can share your location so that others can decide if they might be able to hear the same signal. Second, this is not a beacon but is supposed to be some sort of signal from Israel.

That means this topic should be moved to the right area. (Spy Numbers)

Sorry, I'm not familiar with a lot of the signals I hear, will keep that in mind before posting. This was heard via the University of Twente SDR.

After several repetitions there were different transmissions along the line of "QSL NR05 BT BT AR AR DT40" (The BT and AR presumably being prosigns)

4XZ is Israeli Defence Force located at Haifa and sends mixed strings of letters/numbers groups, probably Spy Station type format.

6.607MHz CW is a regular received here in Australia, it reverts back to a beacon style format when not sending the letters/numbers groups at high speed. :D

Yaesu FT-2000D, ICOM IC-736 HF/50MHz, ICOM IC R75 & Tecsun S-2000 to 450 feet of wire, and a multi band vertical of dubious reliability.
