Main tuning knob not working
My FT-857 developed a new problem. Everything has worked perfectly for years. Suddenly the main tuning knob no longer functions. It has been a mobile unit for about ten years.
Does anyone have any idea how to fix this? Or can recommend a repair service for it? I've tried to take the head a part to see what I can do but I'm just too fumble-fingered.
Anyway, new to the group. I didn't realize how popular the FT-857 is. I've had mine since it first hit the market. I bought an FT-891 to keep mobile. Seems fine but the crazy menu with all the three-letter boxes drive me nuts.

Hi folks...
I have 2 857D's one with a YT-100 and one with the MFJ-939.? I
would like to digital sound card modes with the 857D that has
the MFJ-939.? How do I set up the 939 to work as an external
tuner to free up the CAT port?
I could not recommend another YT-100 even though it has an 8
pin pass through.? It frequently does not tune correctly.? It
has been back to the factory on 2 different occasions for
repair (one warranty, and one I paid for).? Tuning on 60
meters is a pain.? Many times pressing the tune button will
lock the radio in transmit and no tuning action happens and I
have to turn the radio off.? It often leaves the radio in AM
mode.? Sending CW will sometimes cause it to start tuning.?
FT8 will cause it to start tuning even at 5 watts.? I bought
another YT-100 thinking I had a lemon, but also has all of the
anomalies. ? Probably gonna buy a 939 for other 857D, but not
sure how to set it up.
I really like the TUNER function from the face of the radio
with the 939, but need that CAT port.? Any advice is
appreciated.

Phil-san,
Yes, after a while I found the chart said it was for FT-897.
However, it helped me to consider how the jumpers may affect to the FREQs on HF+50, 144 and 430 with VFO steps and repeater offsets.
I have found an INFO on the net which says ¡°Yaesu FT-857 Original Jumper Settings¡± which some of you have known already.
It also says ¡°Radio Type (Look on the Original Box)¡± that I didn¡¯t understand at first glance.
But when I look at my packing box of FT-857, the small labeling seal says ¡°TYP:A2¡± under the ¡°DST:USA¡±.
However, some photos of original jumpers I found on the net were not compatible with any of listed jumper settings. :(
More confusions. hihi
BTW, my 2 cents, it seems J1004 and J1005 are just spares for the future use and currently all the models of FT-857 may leave them as open.
Still considering how I can ReMOD those jumpers for JA compliance.

Leonard-san,
Great INFO!!
Yeah, there should be the different ROM issue. I¡¯ll cross my fingers that YAESU uses the same ROM on all regional models.
Then now the J1004-J1006 are the concerns. :)

Assuming the attachment makes it through this jumper sheet should give
you a good idea how to start.? From my understanding the JA radio have a
different ROM chip so you won't be able to make it 100% JA mode.

Any INFO or pointer that explains each jumper of J1001-1009?
Thanks in advance.

Pitman-san,
Thanks for your comments.
The webpage introduces MARS on the US model.
What I want is to DeMOD MARS and set up a JA model.
I found some photos of JA 857 jumpers talking about 7MHz FREQ extension (TX on 7.100-7.200).
But, for some reasons, their default jumpers are different from one to the other.
Maybe it is caused by the hardware release year so I would like to make sure which jumper affects to which FREQ on TX/RX or both.

It's a very challenging MOD without the ability to see clearly and solder effectively but you can review this.
Most folks want to MOD not DeMOD but these will show you what it looks like stock too.
