Hi LowFers. Too lazy to make quality narrow input filter I tried another thing. I made a loop ant of a shape of square, 65cm by 65cm. Size mainly limited by my wife's tolerance. There are two winding
Hello guys. For the first time, since I got interested in LF, I spent weekend in my second QTH, weekend cottage in JO80CD. As int I used vertical abt 15mtrs with capacitancy hat. Actually, it was 1/3
Hello LowFers. This weekend I proved one old truth. ANTENNA is the best amplifier. I made inverted L ant, where the vertical part was 21 m, the horizontal part is 32 m, most of horizontal part is in
Hello LowFers! As a newcomer I hope I have right to ask silly questions. 1. How efficient is actually capacitancy hat of Marconi "T" ant? In other words, if there is space 40 meters horizontaly and 1
Hello LowFers In spite of heavy QRM this weekend, I heard: IK5ZPV, HB9ASB, I5MXX, DF2PY, DJ1ZB (rather poor), LX1PD (extremely strong, made G3XTZ). Antenna made a little longer, now it was inv-L 103

Hello lowfers! We are probably damned to fight agains QRN and QRM. Recently I had opportunity to buy an external DSP device. I wonder what the experience of DSP users are. Certainly it is great to ha
I do not know how the band is crowded or empty in UK. Maybe it is enough for you to listen few minutes and you hear some station at weekend mornings. Not so in OK. I must listen hours and hours and m
Hello Lowfers. I promise this is a last msg concerning the topic. Let me only annonce that unless I have time enough or conditions get better I will concentrate my effort to first few minutes of an h
Hello Lowfers. This weekend stayed in the city and listened on 40m LW, 6m above ground. I prooved again that this ant is insufficient, giving 40dB lesser signals than the one at the cottage. If I wan
Hi all. I wonder how the LF coil should look like because I experienced following problem. I made "loading coil" on diameter 80mm, length of coil about 100mm. Turn by turn with litz wire. This litz h
