My favourite operation for Ham radio is weak signal communication

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

Welkom in Zuidoost Drente behalve bij de Veron afdeling Emmen

Afbeeldingsresultaat voor welkom in zuid oost drenthe

Dat ik geen lid mag worden van de "zendamateurvereniging Veron" zegt meer over Veron als vereniging dan over mij als zendamateur !!

Wilt u weten wat de aanleiding is van deze pagina,
kijk dan even in het chronologisch overzicht
 Discussing the future of ham radio

Maintaining ham radio is no objective - developing ham radio is

A very true opinion from DF5AI, also with respect to  ham radio organizations

Many national ham radio organizations have a self-conception which is perhaps best described by a self-appointed ham radio government (some of them are perhaps better described by a totalitarian regime locking up its people behind an iron curtain of ignorance)

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

 Read my page on the first ever 24 GHz two way contact between PA and G

 This is how and why I use Spectravue

Me and my small system in front of PB-8 the 13 mtr dish used on 5760 MHz EME

 

         

I have equipment for all microwave bands up to 76 GHz but due to the many projects at this moment only active on 23 cm tropo and EME.

My 2.5 mtr dish for tropo
 

My station:
