Hi Rik, Of course, thats true ;-) Especially when they use a short wire like a dipole for 40m. But that danger can be reduced: You just need a loss resistance that is high enough, hi... But: I don't
Hallo Gerhard, ich nochmal... Wegen der Anpassung auf 30 Ohm: Es gibt mehrere Möglichkeiten, ich nenne mal 3: -Eine Anpassung mit einem dicken Ferritkern (z.B. Schaltung als Spartrafo) -Anpassung dur
Tnx Marco, my first QRSS3 (RX) contact out of the noisy city… Seems to be promising… 73, Stefan Attachment: DD7PC_QRSS3.JPG Description: DD7PC_QRSS3.JPG
Dear LF, I have done some further thoughts/questions about the "gain" between the qrss modes. If the "gain" or better said SNR between qrss30 and qrss3 is 10dB, so can I do a QSO to VK with 1W TX Pow
Warren, LF, Tnx for the info! I am not "afraid" that now many OMs come on the band who just bought their rig, like on HF. Even if you could buy a loading coil, you never will get qrv satisfactorily c
Hey Ossi, I just saw your 2W test on the DF6NM Grabber. Do you mean 2W TX power or 2W ERP? ;-) If it`s 2W TX power, I have to congratulate to your antenna!! 73, Stefan

Hi Alan, tnx, i have printed your article and will read it now at breakfast ;-) Perhaps I will come back with some questions… J 73, Stefan/DK7FC --Ursprüngliche Nachricht-- Von: owner-rsgb_lf_g
Dear LF, Does anybody know about the "gain" between QRSS3 and QRSS10 or QRSS30? I mean, if the noise in both cases is equal, how much can I reduce my tx pwr when switching from qrss3 to qrss10? Or is
Dear Lowfers, I want to start a new subject (for me it's new)... The last weeks I still had RX problems, either with the tx antenna or with the short E-flied RX antenna. I found out that the noise wa
Thanks Johan for the qualified answer! With the receiver bandwidth, do you mean the bandwidth of e.g. the argo programm or of the real receiver, say the ic706? I use a K2 with a bandwidth of 50Hz (no
Dear LF, I will do some RX tests out in the field, starting in about 30 minutes. Will there be some activity? That would be nice! I will listen in CW and QRSS3. I will test until my feet are not to c
Hi Ken, Yes, there is a strong interaction. In principle my active antenna does not differ to the PA0RDT Whip. But the dimension of the interaction depends on the kind of your TX antenna. I think a h
Hi Mike, Bernd, LF, Thank you very much for your transmission yesterday in the evening! I could do very useful tests and improve my little rx-antenna significantly. I'm not sure if anyone who uses a
Dear LF group, I wish all of you a merry Christmas! Thanks to all who gave me a call this evening! Special thanks to Andrej/EW6GB, G3XIZ and IK1HSS! Sorry for the bad rprts and my QRM. Andrej, sorry
Hi Johan, No problem at all. It was just a short info. Gl es 73 es hpe for a qso next! Stefan / DK7FC --Ursprüngliche Nachricht-- Von: [email protected] [mailto:owner-rsgb_lf_group@b
Hi Alan, ;-) No, breakfast was fine like always, perhaps even a little better ;-) What about finbar? Is he still enthusiastic QRV on 137? I have never done a QSO to EI yet and would be glad to get th
