I have made some notes here which hopefully explains how I figured it out. Nothing clever, just lots of print statements and trying to figure out what the hex characters actually meant.
I got an email from my better half this morning asking me what deliveries I was expecting as the postman had left a note. I couldn’t think what it could be and quickly forgot about it.
Much to my surprise, this it was is was…
What a lovely certificate for my (fairly minimal) participation in the experiment. In fairness the photograph taken with my phone does not do it justice.
In a conversation late last year (at the TAPR DCC) I was asked what is the actual level of APRS activity in Ireland. Thinking about the answer for a while, I realised that I really didn’t know, and that got me wondering how to go about visualising it.
I quickly came across Leaflet.heat, a Leaflet plugin plugin for generating heatmaps, so I bodged together some python to grab packets of moving stations from the APRS-IS backbone and put them into a format Leaflet.heat can read. After gathering about 6000 data points, here is what it looks like:
So, there you go, it is fairly conclusive that Cork city has the most ‘on-air’ APRS activity. This is followed by Waterford area, Galway area and then the main motorways.
I was looking for something to watch/listen to while tidying up my inbox today after being away for three weeks or so. We took in the ARRL/TAPR Digital communications conference while in Florida. As I enjoyed this years DCC so much, i went looking for last years DCC banquet speech. Ward Silver, N0AX, gave an excellent talk on the direction the hobby should take for it’s second century. I particularly liked his comment about contesting and being “able to heard the world turn”. Thanks to Gary Pearce, KN4AQ for attending the DCC and working so hard to make the videos available (feed the pig!).
What weekends are for! Wake up, get the billy on and think about what to do for the day.
Last weekend, I joined other members of Tipperary Amateur Radio Group on the farm of Paul, EI3ENB for the SSB Field day.
Unfortunately we weren’t able to get any decent runs going on 20m or 15m which would have helped our score quite a bit, however Eoghan, EI5HBB was at the microphone when we got a decent run on 80m for about 90 minutes in the early hours of Sunday morning.
Looking forward to next year already!
I’ve been recording the “Monthly Average” output from my PV system for a while (Since 2011). Looking at the figures for this summer. The “Sunniest” month was June (91 Watts), followed by August (83 Watts) and then July (81 Watts).
Ok, so July sucked, I think we all knew that. However what surprised me was when I looked at the results from previous years. It appears that the system has produced more power on average this year than any previous year.
To be continued…
The International Amateur Radio Union HF Championship was on last wekend, so, after a stint as EI0HQ Saturday evening on behalf of the Irish Radio Transmitters Society, I did some Search & Pounce operating on Sunday morning.
Since then the first thing I do when I get home is check the post for any new QSL cards, first thing in the morning I’m checking LOTW to see if any new confirmations have come in. I’m even checking LOTW during the day, just in case (94 confirmed this morning). It has become a bit of an obsession!
