To All from PA0SE At 1000 UTC I measured the signal from DJ2LF/P at 144 microvolt/m. From their locator JN49ON and mine JO22GD follows a distance of 435km. Over perfect ground the EMRP would be 64 wa

To All from PA0SE Today at 0800 UTC I measured the field strength of Jim, M0BMU on 137.4kHz, at 11 microvolt/metre. The distance between M0BMU and PA0SE is 329km. Using the curves for ground wave pro
Dear Walter and the LF-gang, Assuming the 360m mast has no top load my antenna simulation program gives a feedpoint impedance of Z = 11.9 - j149 ohm over perfect ground. The reactive part depends on
To Alan and All from PA0SE Thanks Alan for a very useful program. I downloaded it without any trouble and it immediately worked fine under Windows 98. 73, Dick, PA0SE At 00:21 9-7-02 +0100, you wrote
To All from PA0SE Last Saturday I reported that I suffered from strong BC QRM centered on DCF39. I ascribed that to the Luxemburg effect. But in the meantime I found out that this was not the cause o
To All from PA0SE Already several days I suffer from terrible broadcast QRM on the LF-band. It sounds like Luxemburg effect centered on DC39. It is so bad that this morning I could hardly read M0BMU
To All from PA0SE Ruddy, ON4UX, has asked me to put the following message on the reflector. Having heard from me that I use a hybrid LF receiver type LWF45, made by the German firm Teletron in the si
To All from PA0SE Many thanks to all who responded to my request (see below). I will use the suggestion by Geri, DK8KW, with a remark that it has not the status of an official bandplan but should be

To All from PA0SE, I apologize for using the reflector for a subject that has nothing to do with LF. But I know there are subscribers to the list who are interested in cave radio and I don't know how
To All from PA0SE Apparently my remark that the carrier of Droitwich goes downwards during modulation has caused confusion. I certainly did not mean "downward modulation" as we remember it from our A
