My favourite operation for Ham radio is weak signal communication

In quality mode I have heard way too many non quality conversations

En ook in 2022, en in 2023, zijn ze opnieuw blijven zitten,
de leden van het VERON Hoofdbestuur
Bent u ook zo benieuwd wat er gebeurd in 2024 !!

ik blijf zitten

Wat is er gebeurd met de visie van 2016 ??, die visie staat, bijna 10 jaar later, nog steeds op de Veron website:
De VERON moet vernieuwen, verbinden, verbreden en verjongen om
in een snel veranderende maatschappij
haar leden te kunnen blijven faciliteren en inspireren
De enige die niet snel verandert is het Veron Hoofdbestuur
Bent u ook zo benieuwd wanneer het uitvoerend beleid in overeenstemming komt met de visie

Een VERON VR 2022 met "0"voorstellen vanuit de afdelingen !!!!
de vereniging is op sterven na dood, of is al dood

Dat ik geweigerd ben als lid van de "zendamateurvereniging Veron"
zegt meer over Veron als vereniging dan over mij als zendamateur !!

    The moon - mysterious companion of our earth

Michael DB6NT and I made the First ever QSO's between PA and DL on
122, 134 and 241 GHz
and the First ever QSO's within  PA0 on 134 and 241 GHz


Receiving 2021 X-Mas transmission SAQ on 17,2 kHz


After upgrade of my versatower I mounted my 23 cm 70 element antenna, to try how my QTH is on the higher bands

first results are on my activity page

Interested in using the SM7LCB maps and a radar picture, bit more complicated than Airscout but works fine

 added the SM7LCB maps on my website because these are not working on the SK3SE site anymore.

 listen to the big signal from OK1KUO on 23 cm Aircraft scatter, 849 km also good signal in SSB

 Added a simulation off my 24 GHz omni antenna
