You can check RM-009 for shortcut between + & - ....
Hitachi PF series: check visualy for cracks and breaks....

Thats all

If you have hardware (spectroanalyzer and etc) read service manual

Yes, if you have expensive hardware, you can do anything

But again, i dont think sjakie have spectrum analyzers or GSM analyzer.... I am somehow shure that he woldn't be asking questions here about measuring methods....

Yes, true.

Dont have spectrum analyzers or GSM analyzer.
Would want those, but think learning how to use, is too much.

Need to know some easy way to measure with multimeter.
Because have suspion RX/TX and PA i bought are faulty.
