3310 signal problem - GSM-Forum

Destructor · 10-18-2003, 23:29

I search forum and I find some answers but...
So the problem is like this,turn on the phone and network is there and you got network to the time when you wan't to call,then the signal is gone,and when you stop the call,after 10 second's signal is back,sometimes you can make a call.
Thanks...

to raise it and look under, also reflow hagar maybe !!.

I think you should change RF Filters and then if not OK pls change 26Mhz Crystal!!!!!!!

I think, from the sequens of U'r description ,that during the last
PA placement step U may moves or desoders the resistor R532,
( sig. IN).
