Akgis,
that 6210 phone has no TX power or out of control !
try first test VTX at CCONT , and check TXC at COBBA, or reball COBBA and Hager !

Akgis

you need to use osciiloscope to measure TXC at R518 , and TXP at R512 and TXVDET at C802 !

VTX at C142 and also check at V140 (VB and VTX) !

most time, 6210 drop a call or no TX, it is becasue phone was drop down, and antenna switch will break !
