Ultimeter 2100An early birthday present this year: a Ultimeter 2100 from Peet Bros. I had my eye on one of these for a long time because it can do weather telemetry send on APRS. Ordered one from WiMo.
It arrived the other day (see unpack pics in gallery) with a German and original English manual. Fortunately for me because my German is not that good.
Did the glue-thing with the wind cups and test drive the weather station inside. All works fine. Then moved the sensors outside. Wind meter in my antenna mast and temperature sensor in the shade side of the chimney.
Next thing to do is connect the Ultimeter to my Kenwood TM-D710 so the telemetry can put on APRS. That seems quite simple. I put all the settings in and wait….. and wait….. 5 minutes…. 10 minutes…..an hour. No data in the Kenwood. Weird. Switched between I/O-ports on the Ultimeter. Wait….wait….nothing.
Reset the Ultimeter and did all configuration again. Plug the serial cable in it and a few minutes later: tadaaaaa! Weather station data on the Kenwood! That was last night. But after 2 or 3 beacons everything went dead again. No more updates received by the Kenwood. Also: weird wind values appeared on APRS.
But okay, maybe the Ultimeter suffers from RFI, maybe I need to change some settings. We’ll get there I hope! 😉 Anyway, a very cool birthday present!

APRS operatorBob, WB4APR, the creator of APRS (Automatic Packet Reporting System) introduced the term: APRS operator. He wrote about it here. It really gets me thinking about the possibilities of APRS besides position reporting.
As Bob writes: “A perfect example of an APRS operator data
entry station is a home station where a volunteer can serve this
“back room” function. Without even leaving his room, he can
tune to the nets in progress, listen for every tid-bit of information
that is appearing on the nets, and then enter that onto his display
that everyone then at the EOC can see.”

I can see how that works. It would be handy if you’re able to see were accidents happened for instance. These often cause a lot of congestion. Wouldn’t it be handy to follow a Twitter-feed from, let’s say, your local emergency department and somehow reroute accidents from the feed to APRS as (temporary) objects. If that can be done via a script, it wouldn’t even need manual operations. I don’t think that’s the only useful application but maybe it should be one of the tools a APRS operator should have.
The Netherlands is a very small country in comparison with other countries around the world. So APRS is a bit less useful here then in remote area’s. When you want to plot everything that’s happening in The Netherlands on an APRS map, it wouldn’t be readable anymore. If all mobile stations are plotted as well (and they are) it would be one big mush. So we have to be a little selective what to forward and what not.
At the other hand, now there isn’t much dynamic information on the Dutch APRS map besides mobile stations, weather stations and ships. A little more useful information wouldn’t hurt.

If I can find some time, maybe I dive into this aspect of APRS. Maybe I can be a good APRS operator. Would be nice to set up a group of APRS operators and bring APRS more up to it’s potential (at least here in The Netherlands).

20th of December 2012 I ordered a Baofeng UV-B6 from AliExpress.com. About three weeks later (15th January) it arrived at the PA1JIM-headquarters. It turns out to be a UV-B5 instead of a UV-B6. The only difference is the UV-B5 has a rotary dail on top and the UV-B6 has a flashlight instead. That Continue reading
