hi guys
can someone help me with this 5110 that connects only when it has full signal ....
when the signal is lower it doesn`t call at all ...
the signal does not drops from full to zero ...it remaines constant..

10x!

change the 2nd IF filter
you got low sensitivity

in my opinion the problem is tx related ..not rx ... but does it have a number ?? r123 or L123 or c123 .. ??
