Hi thank you for the answer
my call is va2kv sylvain
and the amplifier was an Ameritron AL-82 Linear Amplifier i just sold it
i connected the amp directly to the ACC connector of the icom 7000
and when i tune the amp .. the radio stay in tx and the tx red light is always on
i did a hard reset of the radio and its always in tx
i made a little wire jumper in the dds board ( just for a test between SEND1 and 8VA ) and the radio is return to normal is working well .. but i know its not suppose to be like that with a jumper its a part inside who is defect, but where ???
and the rear mic jack is not working too.. no ptt when i push the ptt button its only transmit with the front mic jack .. the original mic is working well all the button is working i tried the radio on the air
and all station told me that is very good for now..
i try to fix by myself i have the service manual of the icom 7000
