with all the credits going to Eleoson, id like to share this very useful info with regards to netmonitor and signal repair:

Test 01
1)AGCH--->CCCH--->AGCH--->CCCH = no tx
a. 51XX/61XX= P. A. then RX/TX Combiner then Cobba.
b. 3210 = Z504 then P.A. then TX Filters then Cobba.
c. 33XX = Antenna Switch then P.A. then C109 then Cobba then Hagar.
d. Others = Antenna Switch then P.A. then Cobba then Hagar.

2)SEAR--->BCCH--->AGCH--->SDCC--->Restart = MSID problem.
a. All = Update FAID then repair eeprom then Cobba.

3)SEAR-------------------------------------->Restart = Cobba Problem.
a. All = Rework or Replace Cobba.

4)SEAR--->XXXX---->NSPS--->SEAR--->so on = RX Problem.
a. 51XX/61XX = 13 MHz Filter then IF Filter then IF IC.
b. 3210 = IF Filter then 13 Mhz Filter then RX Filters then IF IC then Duplexer.
c. Others = RX Filters then HAGAR.

5)SEAR--------------------------------------->SEAR = Cobba Problem.
a. All= Rework or Replace Cobba.

6)SEAR--->BCCH--->SEAR--->BCCH = Antenna Problem.
a. All = Check Antenna.
