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

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

Phil, Can you post or send me the chart for the FT-857d? Regards, Tony F. Sent: January 27, 2024 10:49 AM To: [email protected] Subject: Re: [FT-857] FT-857 Jumpers Please note this jumper chart is for

Please note this jumper chart is for the FT-897 and does not appear to apply to the FT-857D.? Review of this chart does not match what I have on file for my FT-857D, build date Jun 2004.? Regards,

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. :) 73,

Leonard Pennock, AD7AS It looks like groups may have resized the image so here is a direct link to it. Let me know if this better.

HI Leonard, Where can I get a high res of the jumper chart you sent here? The resolution is so low it is difficult to read, even when expanded. Regards, Tony VA7TF VE7ACF Sent: Friday, January 26,

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%

Hiro KB2LJJ?Modifications for the Yaesu FT-857 is what you are looking for regarding the mods. His website is down. Use link below.? https://f6kop.com/wp-content/uploads/2020/09/857d-ext_2.pdf Tony

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

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.
