Hello: I have an Icom 706 mg2 and it's developed a problem that comes and goes....I will be transmitting on SSB----on 10 meters--with a good swr---all of a sudden the power goes from 100 watts ssb to about 25. If I unkey and then try again---power is back to normal. Anyone else experience this problem? Thanks in advance, 73' Bob WB3DYE
