OH2LX> Incidentally measured frequencies of DCF39/49 OH2LX> yesterday. DCF77 (77.5) and DCF39 (138.83/139.17) OH2LX> are continuously Fs recorded here at our Monitoring OH2LX> Station (qth: Jokela, 60N34 25E00), that's for LF OH2LX> propagation studies. Good idea ! Have done this in Nov-Jan and observed some interesting pattern, loosely related with geomagnetic index. Should you be interested please let me know. OH2LX> Qth of the latter is Burg, perhaps that is why somebody OH2LX> may call it DBF39. The perhaps first usage of "DBF39" I found in an article from Walter Staubach, DJ2LF in german magazine CQ-DL May 1998 page 372. OH2LX> Qth of DCF49 probably Mainflingen?
