A cryptological challenge

Any cryptologists want to try to crack this radio message code?

The British black radio station Gustav Siegfried Eins would include short coded messages in its broadcasts like this.

The text will be in German and suspect either it will be quite easy to break or totally meaningless!

Sefton Delmer explained the code's purpose thusly:

 

The folk on enigma 2000 site would give it a damn good go if its decoding only you want...

 

Yep, decoding is what I'm after. Do you have a link for the site?

 

Two more examples of GSI coded messages.

The newsletters are interesting..go back a few years too..Mostly on numbers broadcasting etc...But some interesting background info on sigint....Lincolnshire poacher etc...
