DK8KW Longwave Information
LF Utility Stations 110-148 kHz (maintained by Marco, IK1ODO)

Considering the recent interest in monitoring band openings and DX opportunities, I decided to update my LF utility station list. The list covers from 110 to 148 kHz.

Thanks to Peter Bobek (SK) and  Gamal Soegiono for data on German stations. All signals have been monitored recently.

Corrections, monitoring reports and help in identifying the unids are welcome.
I expect to repost this list every couple of months.

Rivalta, ITALY JN35SA (N 45 01' 25.6", E 7 31' 09.4")
 
 
111.250 rtty shift 170 (Warsaw meteo, POL) 40 kW  

112.740 - 113340 - 113820 -114200 - 114300 - 114535 - 114940 - etc. until  
117.400:  
Carriers and CW navigation signals (are all this pertaining to DECCA chains?)  

118.800 unid RTTY (NELS reports London, 00,167º W, 51,500º N, 39,81kW - ?)  

122.300 unid RTTY (is this part of the DCF42 signal? - NELS reports 4  
stations)  

122.500 PSK USB + pilot tone (DCF42, Mainflingen) power? - service is  
differential GPS  

126.550 - 126.415 - 126.685 - 126.825 - 126.965 - 127.245 - 127.500 -  
127.780 - 127. 910 - 128.050 - carriers and CW navigation signals like  
112-117 kHz band (DECCA again?)  

129.100 rtty shift 340 (DCF49, Mainflingen, same mod as 139.000,) 100 kW -  
mark frq 128.930  
Luxemburg effect often strongly audible on this signal  

129.525 rtty 50 bd shift 150 (SOA212, Warszawa Meteo, POL) power?  

129.780 unid RTTY shift 100 Hz  

135.750 rtty Greek Navy (Marathon, Sparta) 5/10  

139.100 rtty shift 340 (DBF39, Burg) 100 kW - mark frq 138.830 +/- 2 Hz -  
telecontrol - Luxemburg effect often strongly audible on this signal  

140.220 carrier (DCF60, Mainflingen ?) 20 kW ?  

141.400 unid RTTY shift 100 Hz  

143.890 unid carrier (NELS reports London with 40 kW)  

147.300 rtty 50 bd shift 85 (DDH47, Hamburg meteo, D) 50 kW  
 

 

I have not considered the intermod signals like 136.040 and so on, generated by the German transmitter site.

The powers are derived by the NELS page and from other communications, and are obviously indicative. The indicated power should be ERP, I suppose (?!?).

Receiving equipment (at IK1ODO): RACAL RA1792, Eddystone 1650/8, HP 3586A, W&G SPM-11, Siemens D2009
Antenna: Marconi 13 m vertical, wires
Analysis equipment: HP 141T+8552B+8556A, Hoka Code-3, Spectrogram on SB16.
