To Bob nd All, the signal on 8953Hz was regular cw, RST from DL2NDO 529. Some weeks before Markus DF6NM and me made some tests and found a max. audible distance of 1500m and a max. visible distance o

The far field of a radiated signal, where the reactive E and H fields can be safely ignored in propagation loss measurements, occurs at approximately lambda / 2.pi At this frequency, with a wavelengt
Andy Would be interested to know how you get on with your NOV application for 9Khz. Still have the remains of my old 2.4Khz Tx and Rx and aerials that I used to use for cave radio location work befor
Guten Abend Uwe, DF2BC ist meines Wissens nicht auf dem Reflektor. Hier seine E-Mail: [email protected] 73 Walter DJ2LF Hi all, is Alfred, DF2BC on this reflector ? if not, is his e-mail-adr
Belgium : 2kW output (lifted in 04-2001) Holland : 400W output Finland : 100W output Germany : 20W output (lifted ?) ... just let me explain the German situation: there were 5 special permits for 1
Hello Wolf and All, some additional info about the working conditions of DK3GH - he is living 9Km apart: He has only 12watts out from a two-tubes transmitter (EL84 and LS50), but his 40meters long wi
Hello Martin, In Peter Dodd's book LF experiments page 55 a drawing is shown of a loading coil arrangment. The the coil inductance is adjusted by shorting turns on the coil. Is this right? Martin ...
My experiance of shorted turns on recording heads and transformers is that form a low impedance short that effectivly kills the inductor. Hello Martin, In Peter Dodd's book LF experiments page 55 a d
Regarding variometer design, I have put on my site a simple form that computes the main parameters for the classical two coils variometers, both the sliding and the rotating coils types. It is at htt
Hi all, Judging from the DCF39 data from Brian CT1DRP, the daytime conditions this weekend seemed to be up on the September average by about 10dB. Some of this might be due to the weaker autumn sun,
Hello Peter and All, Some QRN. Good luck. 73 Walter DJ2LF Many thanks for the report and the frequency check Regards, Peter, G3LDO Web <http://web.ukonline.co.uk/g3ldo>
Hi all, very little serious listening from me for some time now as mostly what I am hearing these days is interference from TVs Propagation ....the day-time levels seem to be getting back to normal a
Hi LF-Group, I will be portable next weekend (15/16th), too, operating from our clubstation with a T-antenna of at least 100m horizontal wire in ca. 9m height (or even more). Will be QRV on both satu
Lieber Fabian, im Zusammenhang mit Euren Leuchtturm-Versuchen kam mir eine Idee. Euer starkes Signal, Eure Lage weit nordwestlich in DL, Eure excellente Antenne sowie Eure "Füsse im Wasser" prädestin
Moin Walter, ich bin (leider) nicht bei DF2BC/P dabeigewesen! Der Alfred ist nochmal knapp 200km nördlich von mir ;) 73, Fabian dj1yfk ps.: hab dich letztes wochenende in QRSS3 gesehen, leider keine
Lieber Fabian, danke für die Info. Habe wohl die Zugehörigkeiten falsch gesehen. Macht nichts, werde den Ali direkt anschreiben. Schade, dass es mit QRSS3 nicht geklappt hat und dass ich wohl nicht a
Hi to all slot-watchers, signals sent last night were - 135922.7 to 923.3 : M0BMU in 7fsk (0.1Hz spacing). Jim's sequence can be clearly identified in Dexter's 2nd image: ...51122637... - 135922.3 /.
