Ham Member Lookups: 35754


Born and raised in Amsterdam I came in contact with the phenomena radio during the start of the 70’s. My first transmissions steps where made on CB with two Walky Talkies. The Walky Talky sets where in 1971 replaced by a 23 channel CB set Zodiac M5024. In 1972 the Zodiac M5024 was replaced by a Sommerkamp TS5023 with 48 channels (26.905-27.505 MHz.). Both transceivers had only AM on board and an output power of 3 Watts. I did use a ¼ λ Ground plane antenna at 11 meters high and made contact with 14 European countries. I never had contact with Eastern European stations because there were no stations on air during the 70’s.


In 1978, with the 21st solar cycle and the introduction of SSB on the CB band, I bought a Uniden 2020 with 70 Watts of output power. Having SSB on board and adapted to transmit between 26 and 28 MHz. I contacted stations around the World and contacted nearly all continents, except Antarctica.


Because there was too much interference from other CB stations in Amsterdam I moved to the weekend cottage near Ermelo (Loc. JO22th) in 1971 and stayed there up until 1980. In 1980 with, the licensed introduction of 23 Channel FM modulated CB in The Netherlands and the limited interference protection of these high level FM signals the Uniden 2020 gave, I swapped the Uniden 2020 for a Yeasu FT707. From 1980 onwards I did not use the Ermelo location anymore and was only mobile on air. The Yeasu FT707 could transmit and receive on all the Ham bands plus between 27.400 and 28.000 MHz.. In 1983 I got my Novice license and present Call sign PD0OHW. With the dying out of solar cycle 21 I contacted many stations around the world on the CB Band from my mobile operation. I also take the FT707 on holiday to Germany, France, Spain and Portugal. I was also on air from:

  • Surinam (Paramaribo '79 Loc. GJ25jt)
  • The United States (Indianapolis '80Loc. EM69vs)
  • Venezuela (Angel Falls ‘84 Loc. FJ85un)
  • Ecuador (Islas Galapagos ‘84 Loc. EI49uj)
  • Brasil in the City of Arcoverde in '89 from the house of PY7AJI Loc. HI11ln and from the island of Fernando Noronha Loc. HI36sd.

In 1990 the FT707 was stolen from my Car.


In 1991 I ordered the Yeasu FT767 including the modules for 6, 2 meter and 70 centimetres. At the same time I bought a AEA Pakratt PK-232MBX. I did use the PK-232MBX in combination with an Amiga computer, and I bought a FIF-232C to controll the FT767GX via the computer.


In 1995 I organised the SAIL ’95 Ham radio station event. The station was 24 hours a day on air during SAIL Amsterdam ‘95 event with the Call signs: PA6AMS, PA6TER and PA6DAM (Loc. JO22kj). If you contacted all 3 stations you could get the Amsterdam Award (See award below,second fig.).


In June 1996 I went with a 6 meter group to Georgia (4L6PA) Loc. LN21dw (see for a copy of the license first fig. below).


In 1998 and 1999 to I went to the isle of Pampus (PA6PAM and PA6PUS) Loc. JO22mi.


In1997 onwards I was during Christmas time on air from the South of Germany. The locations I did use where Sint Leonard im Forst (1997 – 2005) Loc. JN57mu, and Bobing (2006-2009) Loc. JN57ls. See the second up untill the third picture below for the Bobing house.


During the last two weeks of September 2006 we where on holiday in the South of Spain near the City of Almuňécar Loc. IM86ds. Sitting outside on the veranda, listen and speak to the world on the Ham bands (see picture top right).


In february 2009 I extended the Digimodes with DigiPan software. I' am using my PK-232MBX in combination with a Compaq Armada 1500c Lap-Top running Windows '95. Unfortunatly the Compaq Armada computer crashed in the second part of 2010.

As a result I'am now using a Compaq Evo N610c 1,8 GHz. computer with windows XP Pro version 2002. The software I use to decode the Digimodes is: MultiPSK version 4.12 (not Licensed). To control the PK-232MBX I use Pc Pakratt II version 5.5A. The controle the FT767GX remotly I use the FIF-232 in combination with Commmander software version 5.8.7.


In September 2010 I moved to the present location, see the two last pictures, where I'am alowed to set up an antenna system. Now I'am using a FD4 antenna with the feedpoint 8 meters above the ground.




On the 23rd of November 2009 I received my EPC number 9506.

On the 29th of Januari 2013 I received my BARTG number 8934.

0n the 16th of Februari 2014 I received my ROS number ERC # 1364 (last Picture)
