Hi Luc, VE2DWE
My setup for 10450-10452 MHz with an IF 146-148 MHz was built for AO40 but tanks to AMSAT-DL it will be fully usable for P3E.
A standard transverter designed by DB6NT for 10368 MHz and IF 144 MHz was originally published by DUBUS 2/ 1991 pag 17 but it was newly described by my self beginning from RADIO RIVISTA 5/1957 pages 38-41 adding all necessary modifications to rise the frequency range 10450-10452 MHz with an IF of 146-148 MHz to be used for AO40 and P3E
here are some characteristics of my setup:
Dish: diameter 60 cm; F/D = 0.38 ; G = 33 dBi
Feed: home brewed Chaparral for RHCP and LHCP
Preamplifier : i0LVA designe ; NF= 1.3 dB ; G= 19 dB as was described in DUBUS 3/1994
Local Oscillator : Designed by i2SG and publisced in Radio Rivista 9/1994 and 3/1995 with a XTAL of 107.3333333 MHz made by Telequartz and designed to work in an owen at 60° C with a RF output of -3 dBm
Local Oscillator Multiplier and Amplifier by 24 ; 107.3333333 x 24 = 2576 MHz module designed by DF9LN and sold by the EISCH ELECTRONIC with a RF output of +12 dBm with all modifications to rise 2576 MHz as described by my self in Radio Rivista 6/1997 pages 36-40
IF output : 2576 x 4 = 10304 MHz ; 10304 + 146 = 10450 MHz 2576 x 4 = 10304 MHz ; 10304 + 148 = 10452 MHz
The multiplication of 2576 x 4 = 10304 MHz is originally included into the transverter itself.
For AO40 and P3E this transverter and the associated setup was intented obviously to be used only for receiving and actually with the poor solar activity of only 67 sfu at 10.7 cm I do receive about 4 dB of (S+N)/N of Sun-Noise

Just a resend first one come out with wrong date.
In view of what's is planned for the next P3E HEO i want to try some 10ghz
band
experiment
I got a local Hamfest a Hughes LNA P/N 1011836-0009 personal earth
station. My first
google search does not give any results nor a direct call to Hughes company who even give less results...
This LNA has a N type connector on it marked IF a F connector marked LNC
another F
marked POINTING and on the side another F connector on probably the LNA model PLV-810A. There is a rotary adjustable ring for
vertical or
horizonthal polarisation and a hand writing note "10-15GHZ KU" the TX power is 1Watt.
If someone is aware ot the use of this PES or know where to get some
manual it will
help me to see if i can put this on the air?
You can see a similar unit on e-bay at
