WWVH 5000 kHz, Radio Enciclopedia 530 kHz, and WNNZ 640 kHz

December 26, 2010: While in Harrowsmith, in eastern Ontario (north of Kingston about 20 km) I spent a bit of time tuning the bands on the Kaito KA-1103, my usual travel radio, using its built-in antennas. Made three noteworthy catches:

• WWVH, 5000 kHz at 0509 UTC. WWVH is the time-and-frequency station in Kaui, Hawaii. I heard it under WWV in Colorado. The two stations transmit the same format, but WWVH is identifiable because it uses a female voice for the time accouncements, while WWV uses a male one. WWVH also announces the time before WWV. Signal was poor but clear. I've logged WWVH on 5000 kHz before, but it is seldom audible here, and I don't think I've ever caught it on a portable receiver with no outdoor antenna before.
• Radio Enciclopedia, CMBQ, 530 kHz, Havana, Cuba, 0545-0601 UTC. Radio Enciclopedia transmits cultural programming across Cuba. I caught them playing so-called "beautiful music" tonight - e.g., the theme from the 1940s movie "Laura". Musical numbers with announcements between them in Spanish by a female announcer. ID and location on the hour. Didn't catch the ID but did catch the location. Fair signal in null of CIAO in Toronto. New station for my overall log.
• WNNZ, 640 kHz, Westfield, MA, 1320-1340 UTC. Morning (after sunrise) logging. Fair to good signal, strongest on frequency, in null of Toronto's AM 640. Carrying NPR program "All Things Considered". 50 kW. Logging a 50 kW station from Massachussetts isn't unusual here, but this is my first reception of this station. Normally the frequency is blocked by my local AM 640.
• I also did a scan for WiFi WAPs using my netbook computer, running inSSIDer. Found four WAPs, all probably local. I don't know if there's any point to doing this sort of WiFi DXing - it's a good way to add quantity to the logbook, but there seems to be no way to know where the WAPs are so there's no way to distinguish between routine local receptions and DX. But they are radio "stations" of a sort, so there must be some way to turn this into a branch of DXing.

The two mediumwave stations were new, so this brings the count in the mediumwave overall log to 955.

WiFi DXing

I am wondering if it is possible to turn the search for Wireless Local Area Network (WLAN) Wireless Access Points (WAPs) into a branch of the DXing hobby - WiFi DXing. Wireless networks communicate by radio, using two bands in the 2.4 and 5 GHz range. Each network's base station can be thought of as being a tiny, micro-powered radio station. By scanning for wireless networks with your computer, you can get a list of the nearby stations of this type. So is there a form of DXing possible here? Is it possible that under certain conditions signals can propagate long distances, becoming DXable targets?

As an experiment I used software called inSSIDer 2.0 that I installed on my station computer to scan for wireless networks in my neighbourhood. The network card has a small antenna on the back of the computer; I didn't try augmenting it. Since I live on the 12th floor of an apartment building I have the advantage of height. There are also other apartment and condo towers nearby, and two main streets with office buildings and businesses, which gives the potential for numerous wireless networks. The advantage of using inSSIDer is that it gives you the number of the channel the WAP is using, which allows you you to know the exact radio frequency. That's not really important for most purposes but it's something you'd want to know if you use a frequency-based logging system.

The results of this experiment were interesting. I did a single scan at 16:36 UTC on Oct. 24, 2010. InSSIDer listed 66 WAPs nearby. Clearly there's no shortage of targets. It's safe to assume all are within a few hundred metres of here. InSSIDer tells you the network's name, the type of device and the network speed it supports. What it does not tell you is where the WAP is actually located. (Or maybe it does - inSSIDER does seem to have an option for attaching a GPS to it, so maybe it can identify the network's location if you do that. But I don't have a GPS). Without knowing the WAP's location, there's no way to tell if a new network you're seeing is a DX reception or just a new nearby network.

I think there's potential to this, although clearly it's not radio DXing in the conventional sense. There's nothing for you to listen to, and you use the computer's wireless card as the receiver, not a conventional radio.
