One data point. I ordered two of the finals boards in July, and I have received them yesterday. The delay was due to the fact that they used my QRZ address, which is a PO Box rather than an street

So, you purchased a radio without knowing a thing about it. Then complain about it, by nitpicking everything you dislike, that you should have resurched prior to purchasing it. Then you buy a newer

The bare boards themselves are pretty easy with companies specializing in low production quantities and even just prototype numbers.? ?I had a similar thought about some of the more popular MFJ

The finals board of the FT817 is literally the simplest PCB in the entire radio. There are around 40 discrete components, including the PCB itself. Not a single IC. There are a lot of very smart and

My take on this is I have a 20 year old radio where parts are no longer available. No surprise there. I'll therefore continue to use it (carefully!) until or if something fails, then I'll do

Not trying to go too much further down the rabbit hole, but... As I understand it, the original FT-817 used a transistor that is no longer available (hence the FT-818 redesigned board), and the

I have often described the FT-817/818 a wonderful balance of compromises, for every perceived shortcoming is a perceived benefit. I want to like the radio, I bought two of them to try it out, but I

Also, it's quite doable to replace the 2 pa transistors on the pa board with a little courage and the right kit. Instead of looking for replacement boards, source a couple of the transistors and put

Hi Ken,? ?I can only offer that the repairability issues are in the same boat that most radios are in. It's easy to forget however that generic parts often remain available on the open marketplace.

While you make a decent point, I think more value is gained from these large, widespread discussions for those of us who own, use, and enjoy our radios. It gives the users of these radios some

Yes, there are some shortcomings for the FT817/818, but I think the advantages make up for those. It is one of the ideal radios to use as a microwave transverter IF (on 144/432 MHz), and for years,

Amen!

You can indeed call Yaesu and talk to the nice part lady and order the parts. However there are none in the supply pipe, so basically you're wasting your time. I talked to the service guy and he said

I've been a member of this group since I bought an FT-817 from an SK estate maybe 8 years ago. I was curious about the radio's popularity and on paper it seemed a great value. Shortly after I started

The original FET are 2SK2975 They are no longer being made. Yes, you can find them on eBay and Aliexpress, but with the amount of labor required to remove/install them, I'd be quite uncertain about

Joe, the pa works from 1.8mhz to UHF. there are no separate finals for the band segments The 817 is 99% SMD, and they are the smallest of parts. Forget the magnifying glass, you'll need a microscope

For the newer boards it is the Mitsubishi RD07MVS1. Take a look to chipsgate if you cannot source them

Ron: I posted this question a while back but no answer yet. ?IMHO the ?best bet is to just buy the final transistors in case we become a member of the club.

Anyone know the part number of the FETs on the 817s PA board??? 73, ron, n9ee/r Ron Wright, N9EE/RHernando Co ARES EC Spring Hill, Florida also n9ee55@...
