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!).
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.
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.
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!
Four of us were sheparded down the River Suir by Frank Deegan and John McGrath (John is pictured below).
We paddled from the Swiss Cottage in Cahir to Clonmel on Saturday, camped overnight on the river bank, just east of Clonmel, then continued on from Clonmel to Fiddown on Sunday. A long trip, though very tiring, it was very enjoyable and I really can’t wait to get out for another trip.
Some videos Frank took during the trip.
You can see my best side in the clip below (I’m in the white hat).
Monday and Tuesday were a different story, two days at Millbrook Off Road Centre (Lantra accredited), being instructed on the finer points of driving off road. Kevin, Thomas and their team were excellent to work with, great instructors. Below is a taster of what you can expect.
They are having a 4×4 Festival the 11th and 12th of July, definitely worth checking out (get off the M9 at Castledermot).
In summary, a thoroughly enjoyable way to spend a “long” weekend!
