I still had the wish to submit the Weather station Utrecht Overvecht to the APRS network to get the data on the APRS maps and maybe even added to the Citizen Weather Observer Program. APRS stands for Automatic Packet Reporting System which allows lots of information to be automatically exchanged. The most well-known one is position reporting, but there is a lot more, including weather stations. It wasn't very hard to get this done, I just had to find the time to do it. The trigger was the mention of a new APRS server in the Netherlands at Amsterdamse APRS server - PA4TW. I played a bit with the perl modules Ham::APRS::IS and Ham::APRS::FAP. Ham::APRS::IS is for communicating with the APRS-IS network. And Ham::APRS::FAP is for parsing APRS packets. I used this module to make very sure my outgoing packets parse correctly before actually submitting them to the network (and still making a few mistakes in the process). I used the explanation and example at APRSWXNET information by Philip Gladstone to find out what to submit and in which format. The interesting point is that wind measurements can not be omitted, but since I don't have a working wind measuring setup I have to enter the '...' values to show that the measurement is not available. And temperatures are measured in Fahrenheit so I have to convert first from my measurements. The current outgoing packets look like:PD4KH-1>APRS,TCPIP*:/161010z5206.6 N\00507.1 E_.../...g...t045h91b10088http://weatherstation.idefix.net/And now the weatherstation shows fine: PD4KH-1 weatherstation on aprs.fi and Weather stations near PD4KH-1 on findu.com. Note how aprs.fi converts to degrees Celcius and findu.com stays in Fahrenheit.
Bij de Veron afdeling Centrum is vanaf 5 januari 2015 weer plaats voor enkele cursisten die de "Novice" amateur radio licentie willen behalen. Voor mensen uit de buurt die nadenken om dat een keer te halen misschien het ideale goede voornemen voor 2015! Meer informatie: N-cursus radiozendamateur Fort de Gagel start 5-01-2015.
: Dalek garbage can. Exterminate all garbage!
: In searching for a TCXO for my FT-857 I also ran across this item on aliexpress and decided to buy it. This should enable me to use a good PC headset on the radio for voice operations.
I wasn't sure why it needs a CAT interface but looking at the windcamp website combined with the aliexpress description I guess this is just a second CAT interface to the radio.

The radio is in the mode I use most at the moment: PSK31 on 10M HF.
I'm not completely satisfied yet with the picture or the placement on the site but it's a start, and it's my picture of my radio which is a lot better than some stock picture.

Lots of spam the last few days for www.omerta.cc. Since www.omerta.cc is a website where stolen credit card information is traded where you have to pay to get in I don't think they really want to advertise themselves. So this is probably a joe-job. Which won't work much since www.omerta.cc is hiding behind cloudflare.
: Really interesting presentation. The one thing I do note is that a lot of experimenting is done with new(er) technologies but people keep beating up IPv4 RFC1918 space (10.x.y.z IPv4 addresses). IPv6 can do so much more and with some thinking about addressing policies a globally routable network can be created which will not clash with any address on other networks.
: Big plans at Amsat India!
"We are pleased to announce that AMSAT India and Dhruva Space Pvt. Ltd. have signed a Memorandum of Understanding on November 30th 2014 to pursue the development of a follow up mission to HAMSAT launched in 2005 on-board the PSLV-C6. HAMSAT II is envisioned to fill the gap created by the recent end of life of HAMSAT and shall continue servicing the societal needs in disaster management, amateur/emergency radio communications and education. Some of the contemplated payloads for HAMSAT II include
* U/V Analog FM Transponder
* U/V Linear Transponder, 50 kHz
* APRS Digipeater
Dhruva Space is developing the complete satellite bus including all the spacecraft subsystems such as the electrical power system, attitude control system, communication system, structure and on-board computer. AMSAT India shall deliver the payloads for the satellite. The satellite is intended to be flown into a Polar Sun synchronous Low Earth Orbit.
This memorandum of understanding has brought together some of the best minds of AMSAT India and Dhruva Space. They are extremely delighted about the association and expressed their happiness on coming together to pursue their quest for innovation in space"
I have noticed the lightning strike detection in Weather station Utrecht Overvecht goes completely mad when I transmit on the 20 meter amateur band. With the detector being quite close to the antenna I can understand this. The solution will be to find a place to mount the detector in the shed. It will be lower (less reception of the radio energy of the strikes) but it will also be further away from my interference. That also means the reading of the detector will have to be done using w1retap since that is what I use on the shed weatherstation computer. I was a bit confused whether w1retap supports this counter but I found out it's based on the DS2423 counter chip which is supported in w1retap, as part of a wind speed meter in a TAI8515 weather station, but w1retap will give the count on readout and the conversion is up to the user.
The fact I couldn't get the DSL linespeed from the Fritz!Box 7360 annoyed me a lot, especially since there is a new telephone wiring cabinet which should raise VDSL2 speeds. I went through a number of websites about getting data out of the Fritz!Box with upnp, and finally I made it work and I get the results I want:Read the rest of Getting the DSL linespeed from the Fritz!Box 7360<NewLayer1UpstreamMaxBitRate>1480000</NewLayer1UpstreamMaxBitRate> <NewLayer1DownstreamMaxBitRate>23144000</NewLayer1DownstreamMaxBitRate>The hint that worked for me was at MRTG en Fritz!Box 7360 (firmware 124.06.05) - tweakers (in Dutch) where it mentiones the changeover to TR-064 protocol which should be reachable over the http://192.168.178.1/tr064/tr64desc.xml url which will ask for authentication with the root username and the Fritz!Box password. More about the Fritz!Box TR-064 implementation at Schnittstellen für Entwickler | AVM Deutschland (in German) which has more documentation at AVM TR-064 – First Steps (pdf, English). This made me end up at doing a SOAP request (post) to http://192.168.178.1/tr064/upnp/control/wancommonifconfig1 which failed. All SOAP requests fail with an HTTP error code 500, but there is a separate SOAP error set in the HTTP status 500 body. I used tcpdump to look at the SOAP error body and found:<errorCode>504</errorCode> <errorDescription>SSL needed</errorDescription></UPnPError>The SSL port is (according to the TR-064 first steps document above) 49443 and the URL is over SSL: https://192.168.179.1:49443/upnp/control/wancommonifconfig1 and this works, giving the answers I want.
: Joined this community because I bought an FT-857 secondhand last summer. I bought it with the idea portable sat ops (walking) would be possible but it turns out I let it sit on the table due to the weight of the radio+battery and wave with the antenna.
I also chose it because I hoped to get into HF a bit. Which turned out fine: digital modes on HF work as soon as there is enough propagation to get signal levels above the urban radio noise.
With some newsitems here on my homepage getting longer I started to feel the need to make a more blog-like format possible with items with an introduction and longer text. And titles here and there to give a better title to newsitems that deserve it. So some changes to the database format, support scripts and all the scripts generating pages. The changes were big enough to update the version number so now it is 4.5.

: A well-produced and very nice video of raising an HF amateur radio antenna on the roof of a building. Using a drone, timelapses and other visual techniques makes this an interesting video of what can turn into a boring subject.
It seems I am a very special person for google: the 'Birthdays' calendar which should be filled with the birthdays of all people in your google+ circles had the option to remove it from the list of calendars or unsubscribe totally. After being on the receiving end of some rants about this it is clear a lot of people don't have the option to get rid of this calendar. I found a possible workaround: How to delete the Birthdays Calendar from your Google Calendar. Update 2014-11-28: I was happy too early: now the calendar is back (without me asking for it) and I can't disable it normally.
