Wonder what others are measuring ?
Number seems about right.
With no signal Minitiouner indicates an RF power of -76dBm then with a signal at -111dBm it reads -67dBm gets a fast signal lock and an MER of 6dB.
LNA was Microwave Modules one with around the same noise figure as you quoted, Receiver was TT3200 pci card.
thanks for the reply - looks as though it's in the right ball park ready for 'air testing' - just hope there's not too many large out of band signals around which may cause blocking problems.
That said the input to the LNA (good old BF981) is tuned and it's followed by a 3 stage helical which gives a well defined bandwidth etc - as per another of my posts elsewhere on this forum.
I'll report back how it works out in practice.
