Laurent, F6GOX, who is one of the primary forces behind the ARP, Radio-Club de Paris, has written a nice little French-language presentation of me since I am a former member of the club. It also includes my interest in Long Delayed Echos (LDE).

Here he also talks about the presentation I gave for the Paris club of radio amateurs on 18 March 2009 on this subject during my year-long stay in Paris. That was a very nice evening which I remember with pleasure.

I also talked then about the interest that the French general Gustave Ferrié (1868 – 1932) took in this phenomenon (The link is in French, but read about Ferrié here in the English Wikipedia). There were French studies of LDEs in Indochina, Senegal, and Mauretania, French territories at the time, which he played a major role in.

Merci Laurent!

I was writing an electronics article today and started to do some circuit analysis by hand. It was a pretty simple circuit so I knew I could crank out the circuit analysis on paper but I started to think maybe there was a better way. I poked around the web and came across CircuitLab.com, a free, online circuit simulator. As … Continue reading …

10m WSPR spots @ G4ILO 17 November 2012

Another day of good propagation. I don’t know why OH1CO was using the suffix /QRP (aren’t most WSPRers using 5w or less?) but it really upset the WSPR encoding algorithm. His call was being decoded at my end as OH1/P00XEK!

I’m starting to believe that my attic dipole does have magical powers on 10 metres. Right now I’m hearing or being heard by 8 different stations but they are only hearing or being heard by me!

A stop-over on my way from Sydney to Oslo gave me the opportunity today to visit Apliu street in Hong Kong. This is where all the electronics products are found. As I had purchased a Baofeng UV-5R from them before it was fun to stop by the 409shop as well. Their address is on their web site, and the word “showroom” really made me expect something larger than what I found. It turns out to be just one small store among hundreds of others in this street.

I bought a handheld frequency counter, Yaege FC-1, and a better antenna, Nagoya NA-666,  for the UV-5R and got a good deal – I like to think that it is because I presented myself as a previous internet customer.

On the other side of the street there was another store with communications equipment as well, Yee Fu Technology Shop, where I bought a 13.8V/20 A switch mode power supply, HK Products Electronics SPS-200MA.

It even had a noise-offset control which I have come to appreciate in my other power supply, the Alinco DM-330MV. It is particularly nice to have on 160 m. How they avoid Alinco’s pending patent on this feature is something I don’t know. There seems to be several other supplies on the market with this feature also, such as the Watson Power-Mite-NF (NF for Noise offset Function), so maybe Alinco’s patent application hasn’t been granted?
