47 GHz - setup


TRV v2.0 IC9100 GPS locked - DB6NT - MVDS SSPA 120mW RF

2,4m solid dish - SSPA driver 1W DB6NT

 VLNA - 1,8dB N/F EB3FRN - 22dB gain

WR22 waveguide switch



DL7YC decoded in test on 47 GHz


RX performance test


Test SKY 90°el. zenith and GND - 2,2dB noise






TRV v1.0 IC9100 GPS locked - DB6NT - MVDS SSPA 120mW RF

SSPA driver 1W

 VLNA - 2,45dB N/F - 24dB gain - JA8CMY design

Beginning of build and first test 02/2020


RX performance of home QTH system with 2,4m offset solid dish

SN/CS = 7,7dB     MN/CS = 0,77dB

New offset dish 2,4m for 10 - 24 - 47 GHz EME




Feeds for 47 GHz in 2,4m offset dish

Complicated process of producing feed horn W2IMU for F/D 0,8 Right now scaled W2IMU feed and working on two of them for testing.


RX/TX switch

will publish here all details soon. Wave guide made by Pasternak MW cost 10.000 $ and have almost 0,5dB ATT with associated waveguides etc.. I have 200 $ solution and 0dB ATT.
