2015-09-03 DAB services scan 3 September 2015 1 day ago
Na alle recente wijzigingen tijd voor een nieuwe scan. Geen van de regionale multiplexen is sterk genoeg om op deze setup met laptop en Noxon DAB+ stick door te komen.

Opmerkelijk: MTVNL heeft een DAB+ audio service toegevoegd, GrootNieuwsRadio. En de MTVNL op 12B wordt wel gezien als DAB dienst van MTVNL maar zonder geldige diensten.

2015-09-02 In Utrecht wel L1 radio, maar geen RTV Utrecht via DAB+ 2 days ago
Net een scan gedaan met de Pure DAB+ radio op zolder. Opmerkelijk is dat wel de regionale multiplex Zuid op 7A goed doorkomt, waardoor ik nu L1 radio (Limburg) en Omroep Brabant kan ontvangen, maar niet de regionale multiplex West op 8A krijg waar 'onze' regionale zender RTV Utrecht in zit. Soms ontvang ik regionale multiplex Oost op 6B waar wel RTV Utrecht in zit voor de oostelijke helft van de provincie Utrecht. Maar dat is dan marginaal en vandaag dus niet.

De opbouw van regionale multiplex west op 8A gaat langzamer dan de andere regionale multiplexen vanwege de kosten volgens Radio Royaal binnenkort via DAB+ in de Randstad - radio.nl
Dat het DAB+net voor de Randstad slechts matige dekking krijgt, heeft alles te maken met de kosten. Op dit net dienen namelijk 18 verschillende partijen, zowel publiek als commercieel, te gaan uitzenden. Sommige partijen willen helemaal niet uitzenden via DAB+, maar zijn het wel verplicht, terwijl anderen weinig financiële middelen hebben. Daarom is gekozen voor een netwerk met een minimale dekking, waardoor net aan aan de licentievoorwaarden wordt voldaan.

2015-08-31 A serious thunderstorm counted 4 days ago
Lightning strikes 2015-08-30 We finally had a serious thunderstorm last night, making us almost jump from the bed at one moment. And the lighting strike counter saw that thunderstorm nicely.

It's quite clear the counts are lower now the sensor is closer to the ground. I'm not sure what to do to get a "good" count again. Last week I placed the 10/20/40m endfed antenna outside for part of the day and noticed that setup also influences the lightning detector in the shed. Raising the end of the antenna helped a bit, I noticed I can use the back gate of our house as the low end of the antenna.

2015-08-30 I participated in the SCC RTTY contest 5 days ago
This weekend I participated in the SCC RTTY championship. I did nothing special to my setup other than sitting down behind the computer and running fldigi in contest mode. I had a total of 33 contacts according to my logs.

I updated the Veron afdelingscompetitie with the latest results.

2015-08-28 One huge Joe-Job for Best Movers Toronto 1 week ago
Over the last two weeks I received an enormous amount of spam advertising Best Movers Toronto. Hundreds of messages. Absolutely no use to me and a really bad way of advertising.

Some searching gave me the idea someone else is trying to destroy the reputation of Best Movers Toronto. Reports about the moving market around Toronto suggest scams happen regular and competition is strong, so maybe some of the scammers got annoyed.

From earlier targeted spam it is clear one of my mail addresses is flagged as 'will report spam' with some spammers, so I get targeted in these attempts to destroy the reputation of others.

Google+Koos van den Hout : Authorities (police and border control) in Melbourne, Australia announced they were going to be in the city center of Melbourne with great force and 'check on visa status'. People weren't amused and a press conference by police attracted a large protest at an amazing speed, cancelling the press conference and ending in a cancellation of the whole plan.

It seems there are people left on earth not willing to live in a police state 'because security' and their voice was heard today. Maybe the rest of the world can take notes.
2015-08-27 A lot more APRS with a mobilinkd 1 week ago
I tried APRS (automated packet reporting service) before and wasn't convinced I was going to use it much. A later attempt in tracking my location on an amateur-related trip from Apeldoorn was also not much of a success.

But, on our recent holiday in the southern part of England I also tried recieving what was available on the 2 meter and 70 centimeter amateur bands and I noticed at a campsite in the New Forest that there was a lot of traffic. I decoded this by putting the android tablet with APRSdroid close to the radio. Part of the traffic was decoded and this gave interesting things such as announcements of local repeaters. I also heard a lot of packets that weren't decoded by the setup with the microphone of the tablet.

So my interest in APRS was revived. And I knew of a much nicer solution for APRS with Android devices: the Mobilinkd bluetooth APRS interface. So I bought one and 'connected' it to my Android tablet. It recieves a lot more local packet activity than my first attempts, I see digipeated packets from as far as northern France. And today I tried transmitting my location on a short trip. The results weren't ideal since the trip was a lot further than the logged points, time to look at the audio settings for transmit.

2015-08-10 Ordered QSL cards from LZ3HI 3 weeks ago
After sending out another batch of QSL cards via the bureau earlier this week I started thinking seriously about ordering them and not printing and cutting them myself. I'm reasonably happy with my design at the moment. And I do like sending and receiving them, so I want more.

There is one thing: I do hope to pass the Full license exam some day. This does mean I will get a different callsign (PD calls are reserved for novice, PA/PB/PC/PE/PF/PG/PH for full licensees) so cards I order now will become invalid at that time.

So I was looking for a QSL printing service that could do not too many cards in black and white for a nice price. LZ3HI offers QSL printing for a reasonable price. And a good thing (for me) is that I can pay him via a bank transfer in Euro's which means there is no extra cost involved.
