I am primarily a CW op and use the FT-857 as my base station.? Lately while using the 857, the power will immediately reduce down to close to zero but I can still hear myself keying..? There have been several times when I was in a CW QSO and the power dropped down to zero (about 1 or 2 w estimate), and I continued my QSO although I was told my signal had dropped some.? In my headphones, I don't notice any change in my keying.? I have checked SWR at the same time and it remains about "0".? I use the MFJ Versa Tuner and the forward power will noticeably drop down and the reflected power doesn't change (always at 0).? Then after a while it may just come back up to full power (100w) and remain for a while or go back down, and come back up or just stay down.? Then after a while, it will work ok until it drops back down, etc.
What is going on with my unit?? Has anyone else experienced this problem?
