Several variables there, band, coax, antenna, etc.??? Sooo…?? -MY-?? FT-817ND measures 380 ma RX ±, 1.89 A TX ±, and my average is generally 800 mAh giving my internal battery about 4 + a little hours of life.

Just the fact that the serial number begins with 8N indicates that it was manufactured in December 2008 which was well after the ND started being produced so it is an ND.

Yes, I first thought I had the FT-817 original and was locating parts using the service manual for that, and then a few days later I was inspecting the final module PA transistors and it hit me, this is the FT-817ND – huh, a welcome discovery indeed. So I was able to find the FT-817ND service manual which is more or less the same, (with the same mistakes) but? additional sections.

?

I agree with others who say the label on the new radios should have read FT-817ND. Perhaps the FCC filing requirements were too onerous for the new batch, or that the original FCC filing for FT-817 covered the 60m band coverage? Who knows.

?

Can anyone tell me the observed max current draw at full Tx power on DC input for the FT-817ND? I am expecting a bench linear power supply shortly, and need to make cables and set the current limit.

I would recommend you get the FT817 "Service Manual", I think it can be downloaded from Yaesu.

?

Your FT817 looks pretty good inside.? So the case is scratched a little, not biggie, it is not dented or damaged.

Hi Samudra

Thanks for sharing the photos. I see what you mean about the hard life
of this rig.

Wow, my original 817 look pristine compared to that one. But then I do
always take care

of my stuff.

For now, I am only sharing from my personal account due to limitations as I do other work on the computer. It's a folder of all photos of the current FT-817ND repair project. I haven't worked out a method for indexing at this moment. No commentary. I am the photographer for copyright purposes. All rights reserved.

That was AFTER they had tried to repair it. I couldn't get anywhere with sliding it off the case, so I used a pliers to tear it off. Seriously
? I'll replace it with a more user friendly and easy to maintain rail/cover/jacket/bag if the radio system comes to life. Maybe even a neoprene rubber cover but that's just an idle thought? for now.
