[Spooks] Morse Code Broadcast

[EI0DB]

Hi All,  First the crud (QRM) out of a cellphone is nothing like a real  
CW (morse) signal. 
I offer as a suggestion that your receiver tuned to 1630 was responding 
to a signal round 2540 kcs   what id known as an "image"  the image 
frequency of your set. Since a superhet (Superheterodyne) receiver works 
by converting the incoming signal to the IF (455 or 465 Kc/s) which 
reduces the number of stages to tune and improves the selectivity, one 
of the drawbacks is that there are two frequencies that can be 
converted  to the IF the wanted and the image.

Sounds like the station was sending it's ID tape, [so the remote station 
could net onto him and ] so some other outfit could not steal his 
frequency. And when there is traffic to send, the operator switches  the 
TX from ID tape to a a message tape, then switches back to the ID tape, 
when finished.

Sounds something like U.S Navy Fleet or NY HF marine radio , message 
broadcast system (may be?)  Key here is messages are just broadcast 
maybe at a schedule time) as they are issued and acknowledgment is on 
another  channel.

Flaw in that reasoning is Navy is just about all RATT or satellite based 
now.
But Haifa Naval Radio  4XZ  (spooks id M22) is still behaving exactly 
like a pre-WMARC 1979 Coast Radio Station. Still sending out their ID 
tape "VVV = =  4XZ 4XZ  repeat ....." , and their encrypted traffic on 
schedule, as well as lists of  call signs for which traffic is held, and 
acknowledgments received.  So much so you would think they are in a 
time-warp. 
Could I  suggest you compare what you are hearing on your radio with 
with 4XZ   which is very nice machine sent morse around 19 wpm,  try 
6606Kcs, 6378Kcs, 5500Kcs (a bit weak here) , or 4330,Kcs     which are 
all very strong in Western Europe (9*W)  around 2100z (GMT) nightly.

best of luck and good hunting Dave
