Hello All

last saturday a "LF tactical team" took a close look on the DCF39 site in Burg near Magdeburg.
The data presented previously in my station profile
DCF39.TXT
have to be updated:

1) One antenna has been scrapped completely
2) The antennas active for emission of DCF39
and Radioropa Info respectively have been interchanged.

<<DCF39.TXT>> Teamleader Geri will come up with a more
detailed report, photos and other surprises soon...

--------------------------------------------
There are 5 (were 6) antennas on this site:


(1) 210m vertical monopole
52d17m21s north
11d54m29s east

This is a guyed isolated tubular mast
used for BC transmissions of
"Radioropa Info" on 261kHz
powered by a Tesla Transmitter 
which is designed for nominal 200kW
but presently operated with 50kW HFout

This is a guyed isolated tubular mast
presently unused
formerly used for MW transmissions

(3) 324m vertical biconical antenna
52d17m18s north
11d53m51s east

This is a hexafilar wire antenna
supported by fabric mast
used for transmissions of DCF39
powered by 
Telefunken Transmitter 
which is a MOSFET amp providing
50kW HFout

(4) triple, 70m octofilar horizontal dipole 
presently unused
formerly used for MW transmissions
(1575kHz Radio Berlin International)

(5) 55m trideco antenna 
> presently unused
> formerly used for MW transmissions as backup antenna
