Yesterday evening I gave it another try to make a contact via the SO-50 satellite. It was hard since someone was trying very hard to work the satellite with 95% transmitting and at most 5% not transmitting which did not leave much room for an answer. I heard that person loud and clear with a repeated and somewhat bored "CQ satellite" and testing noises like whistling, but I never heard a callsign! Pass for SO-50 over my home location JO22NC

Trying to answer that person didn't work (clearly he had a reception problem somehow) so I just started calling CQ on my own when he left a gap. Someone answered but I had a hard time understanding the callsign, I think it started with a D (German callsign) and I am sure it ended with BBE (Bravo Bravo Echo). Looking up the callsign options on QRZ showed me the most likely candidate is DG0BBE so I e-mailed him to confirm.

During our holiday in Denmark I also tried to work a few SO-50 passes. Being on a campsite with a wide open view in all surrounding directions should make things easier for lower passes which I skip at home. I tried a pass with a 55⁰ elevation and one with a 62⁰ degree elevation and I heard the satellite loud and clear. The downside was someone was whistling and calling 'o la', probably the same person as I heard here at home. And another downside is that with lower passes the distance is a lot higher and therefore my 5 watts on VHF don't make it across the FM receiver on the satellite.

I also had a look at possible LituanicaSAT-1 passes but in Denmark those all stayed low to the Southern horizon.

I am active on LinkedIn so I thought I would have a look at the LinkedIn application for android phones.

I was a bit wary of the rights LinkedIn wanted, since it keeps asking me for my e-mail username and password so it can scan my mailbox for interesting contacts. So I checked the rights for the official LinkedIn application in the play store:
This app has access to:
  • Identity
    • find accounts on the device
    • read your own contact card
    • add or remove accounts
  • Contacts/Calendar
    • read your contacts
    • modify your contacts
    • read calendar events plus confidential information
  • Location
    • precise location (GPS and network-based)
  • Phone
    • write call log
    • read call log
  • Photos/Media/Files
    • test access to protected storage
    • modify or delete the contents of your USB storage
  • Device ID & call information
    • read phone status and identity
  • Other
    • receive data from Internet
    • read sync statistics
    • create accounts and set passwords
    • toggle sync on and off
    • full network access
    • read sync settings
    • control vibration
    • send sticky broadcast
    • prevent device from sleeping
    • view network connections
So all kinds of access so it can view personal data on the phone. I am going to skip LinkedIn on the smartphone and I'll keep using it with webbrowsers.

Wat krijg je als je besluit je facturen voortaan digitaal te versturen terwijl je daarvoor nooit de e-mail adressen geverifieerd hebt die klanten geven? Juist, dan krijg ik de factuur voor iemand die een voor de hand liggend e-mail adres van mij ooit opgegeven heeft...
Bijgaand ontvangt u de factuur 2014-0157. Het is een digitale factuur die u kunt bekijken en afdrukken door op deze link te klikken.

Sinds dit jaar versturen wij alle facturen digitaal. Indien jullie de factuur graag per post willen ontvangen laat het ons weten.
Ik heb het bedrijf maar even op de hoogte gesteld van deze misser en dat ze digitaal factureren maar beter pas kunnen doen na een terdege controle van de adressen.

Ze reageren redelijk snel dat er een klein foutje in een adres geslopen is en dat het verder allemaal prima gaat.

Terug van vakantie: we zijn 3 weken in Denemarken geweest. Gekampeerd met onze grote tent op drie verschillende campings. Erg leuk geweest, uit kunnen rusten en genoten van alles wat we beleefd hebben. Onder andere hebben we Legoland bezocht maar ook de kliffen op het eiland Møn. Daar hebben we in 2008 ook gefietst dus het was leuk om wat dingen weer terug te zien.

The heat is on: the Weather station Utrecht Overvecht in our backyard is showing a temperature of 36.0 °C at the moment.

Compared to official observations like the ones published at Actuele waarnemingen KNMI the temperature at my weather station is a few degrees too high. This can be explained by the fact that the sensor in the backyard is in an area between houses and the fact that we live in an area with a definite 'urban heat island' where temperatures are higher than the surrounding open country.

Wardriving results 4 January 2014 - 11 July 2014: 14481 new networks with GPS locations according to WiGLE.

I don't "wardrive" on purpose now, but I leave an android device running the wigle android app on trips that can be interesting such as during holidays.

Google+Koos van den Hout : Trying SO-50 in portable mode, waving the Arrow antenna in the backyard and with a 5w radio. Someone has heard himself very clear and long over the satellite calling 'oh la' and for the rest it was very hard to understand callsigns and nobody responded to my CQs.
I don't see the point in just pointing high power at this satellite and making it nearly unusable for other amateur radio operators.

Sorry for ranting a bit, most here are probably aware of this and use SSB satellites, but I had to get this of my chest. Other times I had more luck, so it's not impossible to work SO-50 portable.
