Has a nice QSO with a very strong ES5AM this afternoon - see attached. Despite the snow the antenna seems to be working so I will transmit overnight on 136.177kHz. Mike, G3XDV == The following sectio
I saw a nice 'X' - the only one all night - on the 136kHz grabber of 4X1RF at 0030UTC. See attached. Very cold here last night (-7C) and the snow on the insulators is dry. Mike, G3XDV == The followin
OK, it seems that most people want full suffixes to be sent. I believe I had good reasons to use a short ID, but I am happy to go along with the majority view. Of course the final straw was Mal threa
The solution is to use SpecLab, see http://www.qsl.net/dl4yhf/spectra1.html This is more complex then Argo, but is much more flexible. Several Eu grabbers (eg DF6NM) use this software and the operat
The attached picture shows a practical demonstration of I-squared-R losses in my loading coils. I lose about 50 watts in the coils in this box - the melted snow is directly above each of the inductor
I will beacon overnight again on 137.177kHz using QRSS60, transmitting 'X' at the start of each half-hour.. Thanks for reports on last night's activity. Mike ==
I shall be operating my attended propagation research tool overnight using DFCW60 and transmitting a full callsign which lasts half an hour. Frequency - Dash on 136.1770, Dot 136.1767kHz. Start of ca
Good signal from XGJ overnight wth deep fades. Attached are three of the best captures, including one at 0900UTC, an hour after UK dawn. Mike, G3XDV == The following section of this message contains
I will be transmitting a beacon overnight, sending 'X' in DFCW60 once each half-hour starting on the half-hour from 1700 to 0900UTC. Frequency is 136.17725 (dash), 136.17700 (dot). Confirmation of ac
A recent message said that JA7NI needed a way to display more spectrum on his Argo grabber set to QRSS120. I posted a reply recommending SpecLab. This raises another issue that has concerned me for s
What's fascinating about this reflector is that I often get several replies to a posting and wonder what they are all about. Then some time later the original post arrives. Presumably the reflector i
Markus, Your suffix is only 18 minutes long but my suffix would take more than twice as long - 38 minutes - to send at QRSS60. The 'X' is 14 minutes on its own. So the situation is not the same for e
I have increased the number of top wires on my antenna- details to follow. To check for pyrotechnics, I will be testing using QRSS60, QRSS120 or DFCW60 during the next two evenings prior to an overni
