PD4U
Dutch Amateur Radio Sation

Welcome on my site dedicated to HAM radio. My name is Marc, 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.

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. My latest activity is experimenting with WSPR Weak Signal propagation reporter. A QRP digital mode that makes decoding possible of extremely weak signals.

I'm a member of the following clubs:

• the Belgium Club SSTV: BCS #076
• the Digital Modes Club: DMC #1244
• the European Phase Shift Keying Club: EPC # 3898.
