[Yaesu] Self Oscillation on 70cm

[John Geiger (NE0P)]

Has anyone else had problems with the FT857 going into self-oscillation on 70cm?  I have noticed this recently where I will key the mic in SSB and the ALC meter will go full scale with no audio.  It doesn't do this all of the time, but only intermittantly.  I opened up the case and tightened all of the circuit board screws which seemed to help a little, but the problem is still there.  Wonder if anyone else found any fixes for this besides sending it to Yaesu or using it as a 2 meter only rig?
