Thanks all, I have reverted to the dry cell tray and some NiMH AA cells whilst I ponder my options. The old Windcamp pack is currently well away from anything combustible, awaiting correct disposal -

Mine died too at 5 years,which is the expected life of the battery chemistry. You could use the empty cell pack with Eneloop cells which last well, but they are a bit light on amphour capacity, circa

Thanks Joe, I was hoping for Lifepo4 not Lipo. But due to compartment size, that chemistry may not be available. I've asked Bioenno the same question. 73 Mike WA1MAD aol.com@groups.io> wrote:

As everyone else has said, get rid of that pack. It’s no good anymore. For a replacement just grab another windcamp, six years is a great service life for any rechargeable battery. I believe you

You are doing the right thing Andy!!!!? For all others in the same boat, GET A NEW BATTERY AND SEND THE OLD ONE TO THE RECYCLERS!!!!? Many people think rechargeable batteries are to last "forever"

There must be a list of lipo cell sizes somewhere to see what might fit in the 817 battery compartment. Otherwise you have to go external. The battery compartment is otherwise pretty useless. It may

Are there any internal Lifepo4 battery options for the 817? That would be a nice option. Undecided on a Windcamp upgrade.

Watch out Andy, they can catch fire Mike WA1MAD

I have some HT batteries that have expanded when they get old after many charges.? Best to remove and replace before something leaks... Within the last month I my original battery with a WinCamp set

Any 11V to 15V 2A PSU is fine, even SMPSU if low RF noise. A "rig" 13.8 V supply can be used but wasteful compared to 12 V. I've used decent 12V 2 A SMPUs from scrapped router/modems that made no

Hi Tony, based on the consideration that power supply units for medical devices must fulfil stricter requirements with regard to interference radiation, I have purchased a power supply unit for

Yes. I believe the voltage measure adjustment is menu item 17 in the service menu. ?But, it’s a measure that can and does go out of calibration, and should be treated as guidance rather than a

Hi, I suggest you read this topic, and use a power cable with adequate section. /g/ft817/topic/incorrect_voltage_reading_on/85137907 Regards, IZ1FHC

That can be adjusted in one of the service menus. 73….Eric VK2VE. Sent: Saturday, 5 October 2024 09:35 To: ft817@groups.io Subject: Re: [ft817] Home Power Supply for Yaseu Ft 818nd I would

Hi Al, If that’s the case, then the 1V drop is quite acceptable as it is also reflecting the voltage drop in the cable from the power supply, especially if it’s a fairly thin one, as they often

It also depends on where he’s measuring it. If being measured at the power supply’s output terminals, then it is probably too much drop, however, if it’s being measured on the FT817’s

I would not trust the display on the radio. I would trust a calibrated power supply or meter. ?Mine is not that accurate, off by at least 1.5 volts.

Ok. Let us know if another ps does the same. I'm running battery, but never noticed. Thanks 73 Mike WA1MAD
