if net moniter showing NSPS ( no signal power save) !
then it mean Hager to COBBA then IP/QP signal is not given !
or COBBA can not do good demod that wave !

so first you have to see that IP/QP wave is ok or not !
then if not, go to check VRX from CCONT supply to Hager !

also you can try to measuer that TX power out going level and frq is ok or not !
if TX frq and level is ok, then it mean COBBA is ok, and PLL loop from ahger to VCO is OK!

then continue, that you have to check that antenna switch , saw fileter to Hager !

if all is ok, then you go to check MAD to Hager via SDATA, SENA, SCLK !

you might need have oscilliscope to "see" !

lot old post in forum , please review and search it !

ps,

if PA is short, then phone will not boot up ( no power) .
drop signal , it mean, phone got RX , but TX might has problem , and you can do lot test with wintesla ! ( ofcouse you might need cracked version or use PKD-1 )

Mates,

Thanks Willy, here is further info on the 3310 unit.

Using Wintesla Test reading range -100 to -108 dBm. So what is the probable cause of this no signal. Heavy interference can be noticed on my pc monitor if I do a call test.
