My favourite operation for Ham radio is weak signal communication

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

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

Aircraft Scatter	My Activity	Troposcatter	EME


- Receiving DL0SHF - experiment receiving Dl0SHF - DL0SHF beacon info - Low cost receiver DL0SHF	Microwave/ MM-wave	My Projects	Information


Weak Signal	Publications	my 23 cm remote station	PathProfile from G0MJW

now on 23 cm	now on 3 cm

aircraft scatter prediction, Get latest info at: www.airscout.eu

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

a low cost RX system for DL0SHF

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 250 W output Take a look what I worked on my My activity page

A new antenna system for the 2 mtr remote station from PA3BIY 2 times YU7EF 12 elements yagi at 12 mtr over ground During Perseids 2011 Peter and I made in total almost 90 MS QSO's We were QRV during the IARU September contest 2015. In total we worked 366 qso's This is what we worked
