Biography of ON2PCO

      a Dutchman in Belgium, how it all started and some history :

  • I got interested in radio at the age of 10 when my father bought my brother and me a pair of walki-talkies. I 'enhanced' these toys by using an enormous amount of copper wire as a 'super'-antenna. Due to the 'DX'-effect (HI) – the number of stations I was able to work with increased 10 times – I got infected by the radio virus which never left me since.

  • I got in contact with HAM radio in 1978 via my neighbour Hans – PE1AAY, who, at that time, operated a 2m station (Kenwood TR7200G/VFO-30G + 14 elements Parabeam) from within his shack, which was situated in the basement

  • 1978 : SWL-station (NL-5944 – VERON). RX-equipment at that time a Cuna SR9 (2m FM-receiver, which I modified for SSB-reception), Grundig Satellit 1400 (HF receiver), home-made inverted-V dipole and an 8-elements 2m yagi

  • 1981 : I developed the 'NL-5944 Morse Tutor + Decoder' for the Commodore-64 computer which I sold numerous times

  • 1981 – 1982 : radio-operator in the Dutch army

  • 1989 – 2001 : HAM-'spirit' at a lower level due to a lot of studying

  • 2001 – 2005 : more active as an SWL (again)

  • 2005 : I passed my exam in Brussels and became ON2PCO

  • 2005 : my callsign changed to ON3PCO and since that time also qrv on HF

  • 2010 : my callsign changed again to ON2PCO (class : B / Intermediate)

Personal biography

  • Name : P.A. (Paul) Coonen

  • Born : June 6th 1961 in Maastricht (The Netherlands)

    My professional background

  • Information Manager (Postdoctoral degree in Information Management, University of Amsterdam)
  • ICT analyst-programmer (Bachelor of ICT)


  • HF + 50 MHz : ICOM IC-7610 including the Heil Pro-Set Elite (headset) and ICOM SP-23 (speaker, 2x)

  • HF + 50 MHz + VHF (2m) : ICOM IC-7400 including ICOM SM-20 (desktop microphone) and ICOM SP-21 (speaker)

  • VHF/UHF (2m/70cm) : Kenwood TM-V71e

  • UHF : Hytera PD-785G (+SM18N2 : external microphone)

  • Some add-ons : Daiwa CN-101L SWR & Power Meter (1.8 – 150 MHz, Cross Needle), Daiwa CN-103L SWR & Power Meter (140 – 525 MHz, Cross Needle), the classic Junker DBGM-Key and the Comet CAT-273 (2m + 70cm antenna tuner)

  • PSU : Diamond GSV3000 DC-regulated Power Supply (max. 30A, 2x).

    Former equipment :

  • HF + 50 MHz : ICOM IC-7600

  • UHF : Hytera MD-785G

  • HF : Kenwood TS-120V SSB-transceiver including the Kenwood VFO-120 (2nd VFO), Kenwood PS-20 (DC Power Supply), Kenwood SP-120 (Speaker) and Kenwood AT-200 (Antenna Tuner)

  • VHF/UHF (2m/70cm) : Alinco DJ596E-MkII handheld transceiver, fully equiped with CTCSS and DCS. Due to the standard TCXO, the transceiver is very stable. I used the handheld mostly during hiking and mobile-operation

  • VHF : Kenwood TR9000 2m All Mode Transceiver including the Kenwood BO-9 System Base

A few pictures of the equipment and shack can be viewed via the 'The Shack'-button on the main page or by clicking here.


  • HF : Fritzel FD4 Windom for 10-80m. This is a so called Off-Centre-Fed antenna, about 41.65 m long (location : in the attic). Because the space in the attic is (rather) limited, the FD4 is partly shaped like an Inverted-V : about 2  times 6 meters in a 110-degree angle and the rest of it is 'folded' horizontally on the both (long) sides of the attic. Though these antenna-conditions are not superb, so far I've been able to work stations all over Europe, Russia, parts of Africa, United States, Canada, the Middle-East, parts of South America, Australia and New Zealand. I'm glad it is working so well !

  • VHF/UHF #1 : 9 elements yagi, vertically polarized, bearing 25 degrees (location : in the attic). This homebrew antenna (DK7ZB design) is used mainly for local QSO's.

  • VHF/UHF #2 : 9 elements yagi, horizontally polarized, bearing 292,5 degrees (location : in the attic), also homebrew.

  • VHF/UHF #3 : Diamond X30 groundplane, used in conjunction with the DMR-transceiver (location : in the attic).

  • UHF (mobile) : PROCOM SF 401/CEL 3 window antenna for mobile use.
