ft747gx encoder replacement
 

All,
I have the regular frequency hopping issue common to the FT-747gx.
One time I came across someone that replaced the clicking vfo knob/
encoder with a smooth encoder. Does anyone know of someone that has
done this? I hate the clicking when trying to tune.

I can't remember now but I had thought they used a 757 or 767
encoder. If I remember right (probably not) it was not a drop in
replacement but had to be hotwired. Yaesu, of course, will not say
anything more than what the direct replacement is.

Thanks for your help.

Take a look at the encoder for the FT-890, it is magnetic, and might work.
If I remember the Ft-890 is an upgraded FT-747 .

If memory serves me right, there may be some pots associated with the
optical encoder timing.

Alternatively, if the part is no longer available, allot of the old
encoders use generic opto-couplers that can be replaced. One of the three
must be out

Or, there is dirt blocking the optics

Hope this helps

I will look into these and see. What I remember from the post I once
saw was that they had to hotwire the encoder they used. I have not
found a drop in replacement other than the original part.

The encoder issue I am having is not an unusual thing. Most 747's get
this issue. I would have thought that at least someone else had done
the replacement using another encoder. The most annoying thing about
it is it not having the smooth dial to spin.

Sorry about the late replies. I was on vacation and forgot to check
this post.
