Thanks for highlighting the full extent of what’s involved here Geert. I watched a video on UT which covered the physical aspects of replacing the finals but didn’t go in to the re-setting

EDIT: I forgot to include the casing of these devices. Here it is.

You may want to reflect on this one. For one, there have been a number of PA module revisions because the semiconductor devices have changed (the old device is out of production). Unfortunately, the

G4BLL, What is the part number for the transistor in the FT817/8's PA.? I'd like to get some. I like dealing with Digi-Key for they do sell what they list, actual manufacture's parts. 73, ron,

Peter, Pretty much everything you've said is correct, I think you've got a good handle on the situation, BUT I want to point out that our discussions so far have been about Yaesu America, your

Thanks for your input Ron. There has been a lot of useful stuff posted on this issue, some of it confusing (to me) and some contradictory. I wanted to ensure that my 818 was in no immediate danger

The problem was not the internal battery running down to 0 volts, but rather like running down to around 5V or some low voltage.? The PA in the 817 and 818 are wired directly to the power input or

Thanks Ken. P Burnett

The self-destruct finals feature is unique to the original, non-nd, FT-817. Your FT-818 should be fine, but I'd suggest pulling batteries out of the unit if you plan on storing it for an extended

I have an 817 (ser. No; 1D) no rf output and an 818 ( ser. no; 8J) still healthy. Do I understand correctly that my 818 will not self destruct if I forget to charge it and the internal battery runs

joe and the group, Yaesu had a 'thing' for using timers to control battery charging. I have a drop in charger for my FT411 handheld and it uses a timer to charge the battery. One issue, is the

I have had an FT817 for probably 10 years. Great little radio. Reasonably reparable with the right microscope and tools. I've done component level repairs. Sure if specific parts fail then the

Sacrifice one radio so several will stay on the air, it's a reasonable proposition in my opinion... Ken, N2VIP

I bought my FT-897 with 2x dead batteries, I've never gotten either to hold a charge. When googling replacements, I was surprised to see availability on Amazon, but never bought a pair. Like many

Dave I always growl and grind my teeth when I see someone parting out a perfectly good fully operational radio on eBay. Damn does that make my blood boil BUT!! I've also turned around and ordered

Ken a bit off topic... what kind of run time do you get with the NiMH batteries in your 897? I've gone though about a half dozen battery packs over the years and I've never been happy with the run
