How I build 1.5m dish
Prime Focus Mesh Dish kit from RF HAMDESIGN. Dish size D=1.5m, F/D=0.45, mesh usable up to 6GHz Gain dBd= 1296/22.2, 2320/27.2, 3456/30.3, 5760/33.9 Linear Tri-Band dish feed 23, 13 & 6cm
10GHz beacon DB0GHZ
1st of July was a good tropo on 3cm to South from me. Copied DB0GHZ beacon located in JO34we, 445km from me. Did a lot of calling to OZ and DL but no response from there. Video in MP4 (H264) format
Rain Scater QSO on 23 cm
Today did a QSO with LA3EQ on 1296.100 MHz mode CW via RS. This is my new #(JO28xj) on 23cm. Scater point map by TK5EP 1.5m dish pointing to rainscater point in JO38

Unexpected tropo to G/GM
This morning, unexpected found tropo path to G/GM. Did 7 QSO´s and best QRB was 1128 km with G4RRA. Signals were stronger from GM direction, as predicted by F5LEN forecast. Tropospheric propagation forecast by courtesy of F5LEN
HB9Q on 70cm EME
Just another QSO with HB9Q on 70cm. With their 15m dish and kW it is a “peace of cake” for my QRP setup 😉
Power/SWR meter
WSPR transmitter updated with a power/SWR meter. For more info about digital SWR meter kit see page Radio-Kits
Modification WCDMA 2170MHz to 13cm
