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)

WX at my home: in JO32sq

 

Added a 24 Hours measurement

My favourite operation for Ham radio is weak signal communication

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

 

Last update:


I measured Return Loss of my 47 GHz feed

I Measured nF of the 47 GHz pre amp and sun noise

Effect on image rejection at system nF

Cooling the LNA using Peltier elements

Updated what's different on 47 GHz EME

Added OK1DFC in the 47 GHz EME performance table

Updated 24 GHz EME performance table, new station: DB6NT


Opened a YIG from my repaired HP Spectrum analyzer




DK2SC has stopped interfering my propagation measurements

Probably the formal complaint at the BNetzAgentur helped

Added Ionosferic Dopplergrams measured from dec 2018 until march 2019

Added some information about the modification of the 250 W 70 cm PA
 

Repair off my Perseus power supply

Will the new Icom-9700 be a game changer for 23 cm ?

Take a look at my video stream of the received signal from PA0RYL

My project: try to use a VSAT terminal for EME

At last some activity again: during 2018 IARU 2 mtr contest

Propagation measurements NVIS 80 mtr beacon PA0RYL

 Added some info on my 250 W 70 cm PA
Added projects page and several projects

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:
2.5 mtr dish at 10 meter over ground

We were QRV during the IARU September contest 2015. In total we worked 366 qso's
