Welcome on my site dedicated to HAM radio. My name is Marc and my callsign is PD4U and I'm located in Apeldoorn in the centre of the Netherlands. My QTH locator is JO22XE. My main interest at the moment is digital modes, especially SSTV. Have a look at my Live SSTV cam in order to see how the propagation is into EU, for testing your TX, or just for fun.
As you can see I'm located somewhat in the centre of the Netherlands. Near the National Park "De Veluwe" in the Dutch province Gelderland, the largest of the twelve Dutch provinces. The city I live in is Apeldoorn. One of the larger cities in the Netherlands with about 200.000 inhabitants.
I'm a member of the following clubs:
My antennas can be viewed on the station info page. My HF antennas are mainly homebrew and consist of: a 1/4 wave GP for 40m, a vertically polarized deltaloop and a dipole for 20m, and a cubical quad for 10m (horizontally & vertically polarized). The quad is the one of the "manufactured" antennas: the Avanti PDL-II. For VHF and UHF I have two beams that come from antenna manufacturers. The Diamond A144S10R: a ten elements for 2m, and the Tonna F9FT a 19 elements for 70cm.
Another activity I have started is APRS. Automatic Position Reporting System. I use the Tinytrack 3 by Byonics on my Yaesu FT-7800E mobile transceiver or Icom IC-E90 handheld transceiver. For more information see my APRS page. I'm also experimenting with WSPR Weak Signal propagation reporter. A QRP digital mode that makes decoding possible of extremely weak signals.
I prefer to eQSL, or otherwise QSL direct. Though QSL's via the bureau are also 100% return of course. So QSL anyway you like!
