I must have had my 817 for about eight years and am still on the original battery. I don't use it very much. 73, Leon G1HSM

I guess Yaesu must make a significant profit on selling new battery packs to replace all the killed packs...otherwise I can see no other reason for not having an "intelligent" battery charging

Like most modern devices, the 817 has a simple press button for power on and off rather than a mechanical switch - that kind of arrangement will always have some residual current drain while off -

No. Same charging method reading the manual. Pietro I2OIM [email protected]> ha scritto:

Does the 817 continue to draw current when powered down? If so, any idea how many mAH? I guess if the NiMH battery is left connected and the 817 is not used for 6 months, the NiMH's will be depleted

I wonder if the new FT-818 does "delta v" charging so the battery charge is terminated when the batteries are actually full?

You could leave the radio on until the battery is discharged, then charge it for the full 8 hours. It won't discharge completely, of course, which is bad for Ni-Cd batteries. 73, Leon G1HSM

Does the FT-817 battery pack normally get hot when charging? I think I read that the charge current is 200mAH? Is this correct? It appears that you need to select different time periods ie 6 hours,

I have just given mine a shake and nothing is moving inside. That said, I had previously wrapped a layer of black electrical insulating tape around the battery pack to create a "handle" to pull on to

That chimes with my thinking. I read that those connectors are rated at 1 Amp per conductor, so they double up to meet the FT81x's demand. Looking at the chosen connector that seems entirely plausible

How old is your 817? It needs to be early manufacture, pre2010 at a guess, for the software mod to work. If it is younger than that you will need a magnifying glass and a fine tipped soldering iron.

The early models of the big brothers(857/897) are the ones where the filters usually failed, I don't think those in the 817s caused any problems. Simon, G0EIY

Mine is an early ND and the software fix worked fine on it Martin G8FXC Get Outlook for Android<https://aka.ms/AAb9ysg>

I never heard of it working on ND models but It won't hurt anything to try Widebander. It either works or it doesn't. Many people tried the software fix on the ND models before giving up and

I have replaced the PA board in my FT817 (old 2004) twice, on my 3rd PA. I ordered the board from Yaesu, was about $65, came with instructions for installing it, is rather easy, do need a current

Where can I find a 817 PA board or at least the PA semiconductors? Cortland KA5S

Hi Martin, Yes, it is purely to spread the load, probably mainly over the connector pins as they are very small, and the radio can draw close to 2A on Tx. 73….Eric VK2VE. Sent: Friday, 29

Maybe that one of the couples is temperature sensing. Are they similar wires or different in size? Pietro I2OIM [email protected]> ha scritto:

The "widebander" software is in the files section of this group. If yours is the right model version. Martyn M0TEB #admin

It is a remarkable little radio - far less sophisticated than the modern portable SDR upstarts, but very capable and a lot of fun at a fraction of the price. Mine travelled all over the world with me,
