hi to all
i have just installed 2m module into my KX3, it works very fine in rx but when i go to transmit i listen noise very high into speaker e during the trasmission the noise change e appear the hi current indication like an autoscillating of final stage.
apparently all work, in rx position che current is about 0,300 mA when transmit 1,8 Amper but about more second late the current groven up to hi current indication, the output is about 3,5 watt!
i didn't find the schematic of module, because i want to check the currente bias setting.
have you an indication to solve the problem?

is it bias problem? or is ground problem?


what is the correct bias and where i can check it?


tks
