Topics:

• Russ’ Raspberry Pi adventures continue. His Echolink node 54711 is now up and running on a Raspbian-based Raspberry Pi with svxlink and Qtel. Russ had to insert “dwc_otg.fiq_fix_enable=0″ into the /boot/cmdline.txt file in order to fix a problem with the onboard Ethernet card locking up. Since then, all has been well.
• Amateur Radio Pi is a forum with the tagline: The interactions between amateur radio and the Raspberry Pi.
• The Society for the Preservation of Amateur Radio (SPAR) will conduct a Winter Field Day, beginning 1700Z on January 26, 2013 and ending at 1700Z January 27th.
• HamSphere is a software Amateur Radio simulator that allows licensed radio amateurs and unlicensed enthusiasts to communicate with one another using a virtual transciever over the Internet. It was designed by Kelly Lindman, a radio amateur with callsign 5B4AIT. The software runs under Windows, Mac or Linux. There’s also a Wikipedia page for more information.
• RepeaterBook is an Android application for locating amateur radio repeaters. There are lots of options, including repeater types and modes (D-Star, etc). It also supports the BlueCAT Yaesu FT-857/FT-817 interface that allows you to tap a repeater entry in RepeaterBook on the phone and it will set your radio frequency.

Feedback:

• Comment via the Web site from Leif, KC8RWR, with another attempt at explaining hard and soft links, which we were discussing in episode 95. Thanks, Leif.
• Leif also commented about difficulties hearing a mobile radio without a speaker in the head unit.
• A very strange voice mail from the Radio Gangsta, aka Rich, KD0RG, from the LowSWR podcast.
• E-mail from gasgasmike, asks if it would be possible to use short wave radio to provide wireless Internet service. Our hosts discuss the practical difficulties with such a scheme. (Note: the use of the amateur portions of the radio spectrum for commercial purposes is expressly prohibited by the FCC.)
• Jeff, KC2QZO, sends his appreciation of our discussion of Codec2 in episode 85.
• Russ mentions that there is another low-bitrate codec is being developed: The Opus Interactive Audio Codec.

As I prepare for the ARRL January VHF Contest, I loaded the latest version of VHF LOG, a software program by Dave W3KM. I have used this free program for many years and it just rolled over to version 4.0 to support Windows 8.

VHF LOG is easy to use while covering the basic contest logging requirements for the usual VHF contests (ARRL January/June/September, CQ Worldwide VHF, etc.). It includes a “Post Contest” mode, which is handy for entering a paper log into your computer for electronic submission.

VHF LOG runs on Windows operating systems, 98SE thru Win8. Check it out.

I had a meeting that I had to attend this evening, but it concluded quite a bit earlier than I had anticipated. I was home by 8:00 PM, so I took the opportunity to participate in the monthly NAQCC sprint tonight. Something I haven’t done in probably over a year.

I am way out of practice!!!  In the past, I would sit down for this contest and I would routinely bang out anywhere from 25 – 40 contacts. Tonight, I feel fortunate to have made 17. That’s way down from my old normal.

And it just goes to show that if you want to succeed in a QRP sprint, or any other radio contest, for that matter, that it takes practice. Radio Sport, as our European friends call it, is not just something that you can sit down and “do”.

It takes practice and a plan. In the old days, I would stake out a clear frequency and run stations. Tonight, I pretty much just searched and pounced. Not the most efficient for running up a score. I never got into a rhythm and the results show.

I will have to get back into the habit of participating in the “Big Three” each month – the ARS Spartan Sprint, the Run for the Bacon, and the NAQCC Sprint. Now that’s the way to seriously fill up your logbook!

From Steve WGØAT on Facebook:

It’s that time of year again! Members of the Buddies in the Caribbean 2013 (Team #1) will mount a mini-DXpedition to Barbados (8P6) 29 Jan 2013 thru 6 Feb 2013.

The Buddipole teamwhich specializes in 100 watt or less low power radios and the Buddipole portable antenna systems will have fixed operations from a ocean villa and portable operations from various points on the island using CW, SSB, and digital modes on 160-10m.

The team consists of the following operators: Chris (W6HFP), Budd (W3FF), Danny (WZ1P), Steve (wG0AT), Mike (KC4VG), Guy (N7UN), Paul (KB9AVO),and Wey-Bob (K8EAB). We all have received our 8P9 callsigns.

QSL via LoTW, eQSL, or mail to operator’s home call (SASE required). See QRZ for individual’s specific QSL instructions.

Sure would like to be able to join ’em!

Sometimes you feel like a nut. Sometimes you don’t. Luckily, Richard’s miraculous recovery from the Creeping Death outweighed Russ’s totally miserable Ides of January, resulting in a listenable episode with a bunch of content–mostly thanks to elcaset, a listener of the show, via IRC. There’s also a bit about svxlink using a Raspberry Pi (yes, it is possible and completely functional) and lots of information about upcoming events. We’d like to thank everyone you who submitted feedback, including The Radio Gangsta, who we also hope will get some much-needed psychological attention soon.

If you think about it, make sure to download the Black Sparrow Media app for your iPhone, iPad or Android device. And please tell your friends about the show. Have them sign up for the mailing list, episodes via RSS, the Google+ community and all the other ways they can keep up with what’s going on in LHS Land.

I have found the solution to a problem that had been bugging me for ages: Omni-Rig did not work with JT65-HF. It was not a major bother for me as it could be worked around by the simple expedient of setting the frequency manually. But after an episode yesterday when I thought I was on 15m and was actually on 20m I decided to look at the issue again.

The solution turned out to be very simple and I stumbled across it by accident. You must start OmniRig before you start JT65-HF! That may seem obvious, but in fact other programs that use Omni-Rig manage to do so without it being run first. Which is why it never occurred to me to try that before. Doh!

Unfortunately the communication between the programs only works one way. JT65-HF can read the frequency from the rig using Omni-Rig but it can’t set it. As I have the JT65-HF source I took a quick look to see if I could fix the problem, but it would not be easy. A major discouragement to tinker with the source code is the fact that the newly-compiled program breaks the link between HT65-HF and JT-Alert. So I am not going to venture down that road. When it comes down to it I’d rather have my alerts than have rig control.
