What’s the use of holidays if you just do nowt? It’s never going to happen in our house. So I decided to do something with one of he old netbooks I have. Remember them? Mine is an Advent 4211 that my lad decided to pull the keys off and eat them whilst our backs were turned and he was a less mobile menace

Anyway. A media server is something we’ve been missing since our NAS decided to go on a ‘go slow’. After 20 mins Googling I ended up with OpenMediaVault. Impressed eh?

An all in one server is almost on us. I did the usual and downloaded the iso, burnt it to a USB stick with Rufus and installed it on the machine. As expected the installation was simple and I used this tutorial to help. Needless to say the 20 mins Googling the right software was the quick bit.

The MiniDLNA bit was what I was after and after a few ‘Uh’s’ and a quick trip round the internet and back and it looks like its going to serve me nicely. Did you see what I did there? serve? server? Oh well never mind. Here’s to you internet and your ability to give me ideas for stuff to do in the holidays whilst I’m waiting for stuff to arrive from China……Now what’s next on eBay?

Many of the larger dealers are offering special deals in the lead up to Christmas. But, are you really getting a bargain? For example, MLS have the FT1200 at less than £1000 after cash back. Maybe this radio is over-stocked as people prefer the IC7300 or the FT991?

Call me a cynic, but I think we are being offered discounts on radios that have not sold. As they say, “beware of Greeks bearing gifts”. If something looks too good there is probably a catch. Of course, if you really want one of the discounted rigs then now is as good a time to buy as any.

The slide down from a solar maximum is (usually) slower than the climb from the minimum to the maximum. Very gradually, the sun is going “off the boil” and solar activity is slowly falling away. With each year for several years to come things will get progressively harder on the higher bands. Some are predicting the next maximum may be a “damp squib”, so enjoy the conditions while they last. It is quite possible that 10m will never be as good again in the lifetimes of many of us. Certainly 10m is already not as good as a year ago. Although Es is good at any part of the cycle in late spring and summer, F2 DX is best around the peak of solar activity. In the past 6m has supported worldwide DX at times, but I think those days are sadly over.

Are you ready for the annual, month-long special event by the Straight Key Century Club (SKCC)? The SKCC Group membership is free, and celebrates the longest tradition of amateur radio: Morse code. But, not just any Morse code. The manual creation of Morse code by “straight” keys means no electronic origin, only mechanical. This is a month-long event, during January 2016, modelled after the ARRL Straight Key Night.

Here’s a video that I made showing my activity as the control operator of the special event station, K3Y/0, during one of the many shifts during January (2015). K3Y is the special event callsign of the Straight Key Century Club (SKCC). The special event operates each January. I’ll be doing this again, this coming month, January of 2016.

K3Y, the Straight Key Century Club’s annual January celebration, commemorates the club’s founding in 2006 following the American Radio Relay League’s Straight Key Night. A small group of participants wanted to extend the fun of SKN throughout the year. The SKCC is the result.

For the first three years, the club’s founders used K1Y, K2A, and K3Y as the celebration’s special-event calls. But someone cleverly noticed that a 3 is nothing more than a backwards, curvaceous E. This “KEY” event has operated under the K3Y call ever since.

The on-air party is open to members and non-members alike. It runs from 0000 UTC Jan. 2 through 2359 UTC Jan. 31. It’s a great time to introduce others to the joys of hand-crafted Morse code using straight keys, bugs, and side swipers.

This year, January 2016, we’ll be fielding K3Y operators in each of the 10 US call areas, plus KH6, KL7 and KP4, along with specially scheduled stations in each of six IARU continental regions. Your QSOs with event operators in all these 19 areas will be tabulated in the Statistics section and can be confirmed with a K3Y QSL card and Sweep Certificate.

The big shack renovation meant I had to put all my stuff back into boxes. No problem spending some time without my rigs and tools, but I didn’t want to spend a couple of months without any form of radio. So I left out the RTL-SDR dongle and a mobile whip to see if I could get some more out of it than digital TV. I have had the dongle for a while now, but I was never impressed by it. Lots of white noise and very few signals to be seen on the waterfall. I even boxed it up nicely to avoid EMI.

The first step was to see if the dongle still worked by scanning the DVB-T bands. After installing the necessary RTL-SDR packages I fired up VLC to see if it would decode signals. There are packages like MythTV and MeTV that can let you watch DVB-T, but I don’t like cluttering up my system especially since VLC is such a versatile piece of software. For it to work you need to open an console though, but the internet is awash with good tutorials to help you get it done.

Step 1: install dvb-apps with sudo apt-get install dvb-apps
Step 2: use the scan application that comes with dvb-apps: scan /usr/share/dvb/dvb-t/tw-All > channels.conf
Step 3: open the channels.conf file with VLC
Step 4: choose your favourite channel and enjoy

Most of the time Linux provides an alternative and in this case it’s w_scan: w_scan -X -c TW

substitute your own country code in place of TW; a list can be retrieved by issuing the command w_scan -c ?

Before I knew it I was watching the WBSC Premier 12 baseball games and found out Taiwan’s public broadcaster is airing Person of Interest. Usually I find that watching tele is just a big waste of time, but I do also find that it is the only time I am not physically active and I do need to rest more. My wife likes PoI too, so now we have a date every Monday through Wednesday at 10.

The FM band was another check to see if the RTL-SDR dongle works as advertised. On Windows the prevalent SDR software is SDR#. On Linux this is GQRX, which is based on GNU Radio, a very powerful but complex piece of software. Before you can start GQRX you need to deactivate the dvb_usb_rtl28xxu driver as this conflicts with the rtl2832 driver. Issue the following command: sudo rmmod dvb_usb_rtl28xxu. If you never watch TV then blacklist the driver in order for it to be never loaded when you insert the dongle.

I could indeed receive FM broadcasts, but as many as I could with my Sangean ATS-909, so no big win there. GQRX also has a build in AFSK demodulator and I tried to decode some APRS signals on our local frequency of 144.640 MHz. I could hear signals and see them on the waterfall, but not decode them. After trying some other antennas and even taking everything outside in the open I grew a bit frustrated and searched for some other signals to decode. Tracking aircraft using ASD-B seemed fun (G4VXE wrote about it before here on AmateurRadio.com ) so I tried to set that up. And in doing so I got a big surprise.
