47 GHz - setup

04/2025 - the new assembly for the 47088 MHz band consists of:

TRV v2.0 and IC9700 - Leo Bodnar GPS locked - DB6NT TRV GPS locked, USB III Microham interface

2,4m solid dish - CT1DMK feedhorn - SSPA (soon)

 VLNA - 1,8dB N/F EB3FRN - 22dB gain

 New WR22 switch and LNA EB3FRN

 

RX performance 9,8 dB Sunnoise and 1,2dB Moon noise


 

First test of EME RXing 47 GHz with DL7YC

 

 

DL7YC decoded in EME test on 47 GHz 10th of May 2024

 


RX performance test W2IMU feed

 

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

Fiberglass dish Prodelin 2,4m

Beginning of build and first test 02/2020

 


 

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

SN/CS = 7,7dB     MN/CS = 0,77dB

New offset dish Channelmaster 2,4m for 10 - 24 - 47 - 76 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.
