Hi, Group. Just now I had see someone FSK signal on 137066/137042 Hz. Unfortunely I have notice only the end of transmission. So I do not know what is this. What can it be? 73 de RA9MB/Alex http://ww
Hi, Bill and Group. Very solidly populated with trees at this location but I have reports from others that experience increased loss with increased ground moisture having no trees. This demands furth
Hi Bill and Group. What kind of soil do you have? Also, what type of ground screen do you have under the antenna? The Lowfer guys in this area (eastern US) experience the opposite effect. In other wo
Dear Mike and Group. (1) It would be very helpful if a pre-advertised DX station would say in advance what is the shortest dot length he will use. Though DX operator do not know what dot length he'll
Dear Alan, Mal and Group. According to the CIS callsign server, his QTH is Novosibirsk, the latitude and longitude of which you could find from your atlas, or Geoclock etc. It is not Novosibirsk itse
Very pleased to have a QSO with UA9OC last night. Good job, Jim! I saw only intermittent bits of signal until about 2230, but then UA9OC was very clear "O" copy up until midnight. When I observed RU6
Dear Claudio and Group. Dear Alex, LF Group, glfer uses X-Windows, and unfortunately the gtk+ library used for implementing the graphical interface seems to be quite resource-hungry... There is a ver
Dear Jim and Group. My loading coil lives outside in a shelter made of plastic sheet over a timber frame. To get rid of condensation, I have an old fan-heater in the bottom of the housing. The 2 heat
Dear Group. I just worked with UA9OC on QRSS3 reports O/O. Such a nice QSO! I have copy audible also. UA9OC sometimes send the callsign on QRSS10. FREQ is 137.7 kHz. But seems most of time they obser
Hi, Group. I have sucsessfuly QRSS10 QSO with UA9OC. Also I saw QSO RZ6LWZ and UA9OC All reports was O. My ERP was only about 10 mW. 73 de RA9MB/Alex http://www.qsl.net/ra9mb
I had copy UA9OC very nice 1 hour ago. But now there is no transmission from them. I try call them but my power is only about 10 mW ERP No answer yet. 73 de RA9MB/Alex http://www.qsl.net/ra9mb
Hi, Group. At the upper leg : SIN(A) * COS(B) = SIN(A+B) + SIN(A-B) (ignoring the divide by 2) after the 90 degrees phase shift at the output = COS(A+B) + COS(A-B) At the lower leg : SIN(A)*SIN(B) =
About year ago I derive formulas wich show elevated conterpoise is much better then conection to the ground or burred conterpoise. Conection to Picture wich show an advance of elevated conterpoise a
Hi Ian and Group. Some of you will have noticed that I have been venting my frustrations about the title subject on the reflector recently and that I mentioned an interesting anomaly in the earthing
Hi Marek and all About a year ago I had touch an antenna when my 50W TX was runing. I had feel electrical shock! It was not too strong for that 2 kV but very sensitive. Skin was burned also. Seems 13
This TOTAL power is spread out in a SIN(x^2)/x^2 pattern. This seems to be strange... May be You mean SIN^2(x)/x^2 ? 73 de RA9MB/Alex http://www.qsl.net/ra9mb
