Where are all the German stations on 136kHz? There are French, Italian, Russian etc, but very few Germans. Are they all listening on 500kHz or is the splatter from DCF39's data bursts too bad? Mike,
A friend in South Africa has obtained a marine MF radio but can't find any info. He says it's a Redifon G474, but the Internet has nothing to say on that subject, so perhaps it's known as something e
There was some open wire around when I was a BT (Post Office) apprentice. It was solid copper wire. As I recall, dropwire (steel with a thin copper coating) had a limit to its usable length because i
David is quite wrong in thinking that any lack of technical articles in RadCom is because the Editor wants a quiet life. There is almost no backlog of construction articles, but many on expeditions e
As Managing Editor of RadCom in the 1990s (and having worked in the RadCom office as a freelance temp for several months recently) I can confirm the comments by Rik and Alan that the content is very
Sorry I didn't see Gerhard's message early enough. I called CQ on 137.650 twice around 1200 Sun, but no callers. I am happy to set up skeds and am available most days. Mike. G3XDV --
Last night we had a freak snowstorm in Hertfordshire. 3 inches and the trees are still green! In nearly 60 years I don't recall seeing snow so early in southern England. Attached is a photo of my ant
Another pic of my antenna sagging under freak early snow in southern England. Hi res (2Mb) available at http://homepage.ntlworld.com/mike.dennison/index/lf//DSCF1059.jpg Mike, G3XDV == The following
Nice activity on 136kHz this morning - possibly fuelled by the expected OE activity or maybe the CQ WW 160 contest this weekend. Worked DK4U (549) on CW. Also heard CW from G3YXM (599) and G3KEV (589
This does not follow. On the HF bands the ERP is close to RF power, especially on the bands where WSPR is popular, and can therefore be used a a rough approximation. That is most certainly not the ca
Dave Riley write about loop antennas: There are two 'cons' that I can think of. One is the weight of the low-loss wire required. This would cause a problem in my own case as local restrictions lead m
Good signal from XGJ last night from WD2XGJ on 137.7798kHz starting at 0300UTC. See attached. Mike, G3XDV == The following section of this message contains a file attachment prepared for transmission
Thanks to Harry, G3MFW, activity was fairly high on the 136kHz band this morning. I had QRSS3 QSOs with G3MFW, F6BWO and F4DTL, and saw part of the transmission of OE5ODL. Well done Harry. Mike, G3XD
Very good reception of WD2XGJ on 137kHz last night. The callsign was readable from 2352-0032, then nil until 0234 when it was solid to 0613. Attached is the call starting at 0452 and is one of the be
A busy day today on 136kHz. In addition to my earlier report is PA3CPM whose QRSS3 was audible. I also managed to work OE5ODL (952km) who finally popped out of the noise at 1715UTC. We exchanged 'M'
