2320 MHz Activity

My activity on 2320Mhz.

 

Station outfit:

Transceiver:                 TS-2000X - DEMI Transverter

Preamplifier:                G4DDK   -    0.5dB

Final amplifier:            90Watt SSPA        

Antenna system:           3m solid dish, Andrews prime focus - 34dBd / Beamwidth: 3.0degr / Septumfeed modified for f/D 0.32

Control system:             VK5DJ - Stand alone interface

 

 

 

February 2011       Decided to expand the dish system with yet another interesting frequency band: 2320MHz.

                              Currently collecting the various parts for this band.

 

March 2011           On the fleamarket we bought 2 pieces of Andrews SSPA amplifiers which will need some modification in order to be used for 2320MHz.

 

July  2011             Completed the DEMI transverter.

 

January 2012        Completed modification on the Andrews driver section: 30dB // 25Watt

 

January 2013        Completed modification on the Andrews final section: 150watt

 

January 2019        The Andrews SSPA driver sections FLL15 and U17 died for unclear reasons. The SSPA was replaced by another unit with 90Watt RF out.

          

March 2019           Installed the 13cm transverter, SSPA and antenna in the dish for the first EME QSO on 2320Mhz

 

August 2019          Installed Choke on the feed and added RX for 2304 / 2320Mhz

 

October 2020        Added RX capability for 2400MHz
