Mike, That was awesome feedback, most every previous report missed one or more pieces of information. Thank you, that was helpful, Ken, N2VIP

Hi Ken.? Not sure if you were asking me this question, but I ordered the final boards by phone from Yaesu in the US.? I called the Contact Us/Parts number on their website. I don't remember if I

Yeasu releases new Owner's manuals as the externals and user interface change. There've been maybe 5 or more released for the FTdx10 so far. Makes sense as more of the product becomes software

Mike ordered and was shipped a finals board from Yaesu US recently, as noted here - /g/ft817/message/115294 Please, describe exactly what you asked for and who you asked for, for

Yaesu said they were no longer available as of early September 2024. I ordered a board from a place in Germany called funktechnik.

Excellent job Nick, Glad you got it fixed, good for a few years yet. Andy

I got around to completing this repair today. Yaesu sent me a Q9000795 rotary encoder (Alps, appears to be identical to the original one), they also sent me a new knob RA026960B. Total cost including

Pietro, just for a little more info can you take a picture of the display when this is occurring and post it here? -- Al Skierkiewicz WB9UVJ

The finals are only one place that you can lose power. Drivers, Predriver, transformers, and (on mine) one of the power switch transistors to the predriver supply all can cause low power. It is quite

Yes, and presumably the 'new in box' FT-817 the OP got would have that issue... Ken, N2VIP

The self oscillation problem on the original 817 can be dealt with on the older original PA board interface by reversing the phase for the input to it, I've done that to each 817 that has landed in my

The original, FT-817 finals used transistors that are no longer available, so technically the rep was correct, BUT... The FT-818 has a (slightly) redesigned finals board that has a new, readily

Mike, Besides the normal "transmit into non-resonant/non-existing antenna, blow finals" issue a Z817 can help with, there is the "battery pack drains, the finals self-oscillate and fry themselves"

@ Al WB9UVJ ( /g/ft817/topic/power_output_instable/108372017 ) Thanks Al. That's what I was hoping for. No luck... Pietro I2OIM

Were these FT-818 finals or FT817? When I called a couple of months back, the service guy told me no 817 finals are available and none are planned on being made due to lack of transistors

I recommend getting the interface cable for it, if you don't have it, so it reduces power during tuning. Mike KA2JAI

I bought a finals board for my 817ND from Yaesu UK last month. It arrived in two days. -- Mike G8GYW

I recently got a new in box 817 non ND. I just got the z817 tuner. I sure hope I can protect the finals with this setup. Any protection suggestions? I don't think the first gen 817 can be repaired

I ordered them directly from Yaesu by phone. Mike KA2JAI
