Wow, 100kW on LF with a 1,000 ft mast.
I am jealous  :-)

German EFR (*Europäische Funk-Rundsteuerung* 
<http://www.efr.de/com/download/pdfs/radio_ripple_control.pdf>) are to 
broadcast control signals for utility companies on 135.6kHz from a site 
near Budapest. Although this looks like a potential cause of QRM in the 
band, the present sites at Mainflingen (129.1kHz) and Burg (139.0) are 
mostly plain carrier with occcasional bursts of data and are fairly 
benign. The English PDF, linked to above, shows the new TX service area 
but gives no other information. The German version quotes it as 100kW 
with a 280m mast, similar to Mainflingen in erp.
