[Yaesu] FT-847 question

[KBØNLY]

The knob on mine is nice and smooth and doesn't appear the least bit wobbly. 
However, it's from later in the production run.  I have seen many with the 
wobbly knob problem, it's due to errors in making the knob itself, nothing 
wrong with the actual radio hardware.  Some of them seem to have the shaft 
hole slightly off center.  I fixed one by filling the shaft hole with epoxy 
and drilling a newly centered hole, it took a lot of time and patience, it 
worked perfectly in the end but honestly wasn't worth all the trouble in my 
opinion but it meant everything to the owner of the radio.

The power switch is a common problem with the 847, and I would almost bet 
that if you send it back for another one with a good power switch eventually 
it will fail anyway.  Your better off just opening up the radio and fixing 
the power switch in that one and keeping it if everything else is ok.  It's 
a quick and easy fix and there is plenty of info on the net about how to 
swap the contacts around in the switch, etc.  Another thing to do is once 
it's fixed turn the radio on and off by flipping off the power supply 
running it instead of using the power button, that is if you don't the power 
supply on to run other items.  But, even if that's the case a relay or 
switch inline with the power cord is another quick fix.  I have been 
shutting off the power supply instead of the radio power switch on mine 
since I got it years ago, no problems, and the power switch hasn't failed 
yet.  So I assume the problem lies in regular use of the switch, it just 
wears out.
