I know by now most of you are bored to tears with this THREAD. So this is for the folks who have the same problem as i do but were afraid to asked.
With the help of some of the most famous EME GURUS i proceeded doing the following test that THEY suggested.
1) 50 ohms dummy load on the IQ+ INPUT FLOOR NOISE 5DB ON MAP65
2) ANTENNA CONNECTED (IQ+ TO SPLITTER LNA ON) 22DB WITH ELEVATION OF 15 DEGREES IN THE CLEAR OVER THE OCEAN
3) ANTENNA CONNECTED (IQ+ to SPLITTER LNA OFF) FLOOR NOISE 5DB ON MAP65
CONCLUSIONS: THE 16DB required are barley enough 22db -5db floor noise =16db RF GAIN & very often depending on the AZ/EL it can go down to -19db -5db = 14db RF GAIN well below of what is required. So I will have to work on increasing the RF GAIN to the IQ+. I guess if i took out the splitter i would probably gain 2 or 3db but i do not want to do that.
I want to thank Leif SM5BSZ, Conrad PA5Y, ED KL7EW for their help:)
