The following is available in Dutch only, original articles referring to in
  UK Radcom April + May 1999
The above link brings you to an English PDF version of the Radcom articles (200 KBytes). It refers to an article in Dutch in Electron about my coax loop-antenna, a hughe thing of 150 square meters, with special Rx results.
G3XTZ refers to such a Rx result in his article (200 KBytes) in Radcom from Februari 2000.
I am mentioned!!

If PDF's won't view properly copy to hard disk first!!

More detailed information in English added on the extra radio page (see top of this page, right)

The Dutch part with all the publications in Dutch from me are moved to a special page in Dutch only.


VERON PE1ABR





This part is to activate some memories to the fifties and sixties.
Memories to the electronics hobby and a magazine to popularize electronics for the youngsters from those days.
It was called Radio Blan, the young tinkerer figured in these stories, his father and grandfather/Dr. Blan


Dit gedeelte is bedoeld om herinneringen aan de jaren vijftig en zestig op te halen.
Herinneringen aan de elektronicahobby en een tijdschrift uit die tijd om elektronica te populariseren voor de jongeren.
Het blad heette Radio Blan, in deze verhalen figureerden de jonge knutselaar, zijn vader en opa/Dr. Blan.
Achter deze link meer typisch Nederlandstalige zelfbouw zaken en een aantal beginners boekjes.


Alle rechten en copyright van alle vroegere producten van AMROH en uitgaven van voormalig "De Muiderkring " zijn tegenwoordig in handen van    Bureau Belper.   Mochten bepaalde zaken zoals Dr. Blan opnieuw uitgegeven worden dan kunt u die daar bestellen!

Again some words in Dutch:
Dit wordt de tijdelijke rustplaats van de hersenspinsels van Walter Geeraert  -  PE1ABR.
This place will become the temporary resting place of some of my brain-waves
