best
This is datv station for qo100 as mentioned
Wtf ive just saw
Bro what’s s that
THIS IS DATV TRANSMISSION AND SSB HARDWARE ON QO100 SATELLITE
Если бы мы знали что это такое, но мы не знаем что это такое!
Did not understand what you are doing
Congrats on your DATV on QO-100, I'm receiving you right now! 73 Nigel, G8AYC.

Very good! Congratulations 73' PS8ET
If I use it to boost my fm transmitter signals how much output watts will I get?
depends on ur input signal power plus amplifier 20db gain , but it is about 8 db gain at fm freq and it has 1db compression at 100mw as max , so for fm and depending on ur signal power input , about 1 to 5 mw max
The antenna is home made , using 2.5 mm copper tube used for refrigerators. Being flattened and cut to the required length and the vna is used to resonate it at the required freq
As per lebanese ministry of telecommunication band plan list , amateurs are allowed to use 2.3 up 2.48 ghz freq
Planning upgrade for dish . To go from 1m to 120cm dish better for DATV
System cost till now 1700$ , programming languages used C , visual studio . Controllers used raspberry pi 4 and ardiuno nano . Nodered programm is used to control every thing from PC . Bullseye is used and has better gain than dxpatrol lnb , but since dxpatrol oscillator is external it has better freq shift than the bullseye

اتصالات عسكريه على هذه الترددات؟ اي عسكر؟
Where is the loop?
My anti friend , it's not a magnetic loop antenna , but endfed antenna but with long wires so instead to go up and cut wires to tune it , usually a capacitor is soldered between ground and rf in , so I added near the radio a variable capacitor which is used for magnetic loop to Handel high voltage and up to 150 watt which will not arc at this power , adding the capacitor will cancel part of the inductance from a long wire and tune the antenna to disaered freq band . It's an out of box solution , but still u can go up to roof cut the wire and using vna u get what u want a fixed tuning , what I have a variable one .
Nice my friend, I am not anti friend but after I talked to Hani Raad, I understand why you do this, it is the same in my position with Jordanian Society, but I wish you the best, you know about ham Radio more than the entire RAL
Explain what you are achieving
Rf combiner for the 2 meter band
Measuring isolation , and loss ,.getting up to -40db isolation and about -3db loss . Excellent
VERY NICE WORK, I WISH YOU EXPLAIN THE SETUP, THANK YOU AND KEEP UP THE GOOD WORK. IN MY OPINION YOU SHOULD TAKE THE POSSITION OF RAL CHAIRMAN, 73S GOOD LUCK
I wish that is true, you guy's need to get rid of the old RAL
