Some time on the afternoon of 21 May WebProp stopped updating. The first person to notice it (actually the only person to notice it) was Mirek, OK1DUB, who sent me an email.

This is a screenshot not a live instance of the program

I SFTP’d into the web server to check and sure enough the files containing the propagation information extracted from the WWV 3-hourly bulletins had not been updated. They were updated when I ran the script manually so my script was OK. The likely explanation was that cron, the Linux job scheduler, had stopped running. I filed a ticket with Hawk Host‘s support department.

They claimed that cron was still running, though the evidence of my own eyes showed that it wasn’t. It took me a while to convince them that there really was a problem but we got there in the end. This morning when I logged on to my computer the latest propagation information was being displayed again. Hopefully my cron jobs will now stay running.

It was a nice night for DX.  I guess there are a lot of folks out there getting their stations ready for the CQ WPX contest this weekend.  They seem to be swinging their beams to and fro, checking out their Amps, and burning the dust off their finals.  Good times for a QRP DXer, good times!

I started off the evening with a brandy new one.  7X4AN, Mohammed in Algeria on 15 Meters  And with QRP, to boot!  So it was a deuce – new DXCC entity worked with QRP.  That was followed by another QSO on 15 Meters with KP2M down in the US Virgin Islands – and was he ever loud!  10 over 9 at least!

From there I went down to the 20 Meter QRP watering hole and called CQ. I was answered by Cliff W9ZI in Wisconsin.  Cliff and I chewed the fat for about 20 minutes until the band started changing and we cut things short before we both QSBed into oblivion.

That was followed by two quickie DX/Contest style QSOs, both on 20 Meters.  I am in the log of Zygi SP5ELA from Warsaw, Poland. Dziekuje, Zygi!  Then over to the Azores to get into CT8/OM7GJ’s log.  He had to be 20 over 9 here in NJ.

Lastly, I went to 17 Meters and worked OM3SX. Mike in the Slovak Republic. Mike was about a 579 here and I received a 559 in return.

In addition to the WPX this weekend, don’t forget that Saturday night, from 8:00 PM until Midnight – local time is QRP ARCI’s annual Hoot Owl Sprint.  That’s always a fun one.  There are bonus points given to anyone who operates portable.  I don’t know if I am intrepid enough to venture out at 8:00 PM this Saturday evening.  I’ll probably sit in the shack in order to just give out points, as usual.

Then come Monday evening, the MI QRP Club will be holding their annual Memorial Day Sprint from 2300 UTC to 0300 UTC..  That’s always a fun event.  Two good QRP events to keep in mind this upcoming long holiday weekend.

Greetings, listeners! May we entice you with another episode of Linux in the Ham Shack? We sure hope so. In this installment, we have a special guest, Peter64, ubiquitous podcaster of Kernel Panic Oggcast fame. He gives us a decidedly downunda perspective on our topics for the evening. Speaking of topics, we have several: new releases, including Debian "Wheezy" and KDE, updates on previous topics including the Tucnak logging application and the Hamux live distro, based on CentOS. Finally, we take a look at a clever and addictive airplane tracker that uses FAA and ADS-B transponders to let you know where your loved ones are when they're at 35,000 feet. G'day from the team. We'll keep a shrimp on the barbie for ya.

After I posted my picture of bicycle portable yesterday, my pal from Cheltenham, Simon, G4SGI asked if I’d seen his bicycle mobile video. I had seen it but I watched it again last night.

It’s well filmed and I think inspiring! I’m sure some of you will enjoy it too. Quite apart from the well thought out mechanics of Simon’s bicycle mobile station – I am very impressed about how he is able to speak clearly whilst travelling at a good speed!

Well done, Simon and thank you for the inspiration

I have just spent what seems like several hours trying to find out why my weather station data sent by Cumulus to the APRS network vanishes without trace. I have tried using the wxnow.txt method of generating APRS weather objects in APRSISCE and that does work, but unfortunately it messes with the MYCALL setting in my Kenwood TM-D710 converse mode TNC. So I thought that I would avoid the problem by getting Cumulus to send the data to APRS-IS directly.

The data packets were being sent but they never showed up on aprs.fi. I produced debug logs for both Cumulus and APRSISCE. These showed the packets being sent. So where did they disappear to?

To cut a long story short, Cumulus was sending the data packet with a path of TCPXX*. This is listed as “deprecated” in the APRS spec but it is actually blocked by the APRS-IS network software. The CWOP (Citizens Weather Observer Program) which I believe runs on an older version of the software, is not so picky so no-one had encountered the problem before. Can you believe that I must be the first person to try sending weather data to the APRS network using the Cumulus software?

EI9KC (2nd from left) and Anthony

Very rare during the week do I have time to get on the radio once all the things around the house are done I am beat... BUT this evening was an off night were I was able to power up the K3. It was 30m were things seemed to be happening for me. I was able to "hear" lots but contact few, there was lots of South American stations calling CQ but my 5 watts just did not seem to make it down that way. I had a look at the P3 to see what stations were showing up and I came across a very weak signal. I was not able to make out the call but then as 30m does the call came in at S5 just right for me decipher the call. It was EI9KC from Ireland now for some reason I do have a very hard time with getting Ireland in the log. I took a chance and threw my 5 watts out there and EI9KC came back to me! Ark gave me a 559 report and considering the band conditions, my attic dipole and the 5 watts I was pumping out I was thrilled! The trouble at this end was he was in and out BIG TIME! It was a very short QSO but I did email him just to make sure Ark knew I did copy him and I wanted to make sure he got my call and did copy me. He emailed me right back and did confirm the contact and low and behold he is a blogger as well. You can check out EI9KC's blog here, Ireland has a special place in my heart as both my mom and dad are from there. Funny thing and small world I did a search on Google regarding EI9KC and I found out he knows a fellow blogger Anthony EI2KC   (first ham on the left of the pic above).
