Oh, OK. I get the USPS scam emails all the time. I'm waiting for an Ali Express delivery of my battery pack kit. ETA Dec 14

It's not eBay, but AliExpress. ??
The word I got was that it's a shipping scam. The individual vendor shorts the postage, and then expects USPS to deliver it anyway, collecting the postage due. USPS tracking says they're not accepting the package for shipment. ?I've had this happen a few times. When it's from an individual, and just a bit short, I get a note in my mailbox to come and pay. ?The Chinese packages are a different story.?

I agree. It's just hung up on the way. I do most of my business with eBay dealers. Hardly ever a problem.

Re: Internal battery FT-817ND
If you have a fully adjustable power supply for voltage and current limiting, all of that can be lumped together as a single overall limit to suit the entire setup observing the specs of all elements. It's from that perspective that I commented. Joe?

Yes and no.

The initial inrush current *could* be interpreted as what your charger PSU
might have to handle if you try charging a discharged pack with it and
thus the charger / psu should really be built to handle this current if
you don't want to let out any magic smoke from it.
?
This is normally higher than the SAFE charging / float current, which of course
should be limited to approc 1/10th of cell capacity.

So if you had a 10ah pack then you never really want to have 1 amp flowing
at any one time into it, otherwise you you'll screw the cell pack.

Ignore my jumper comment...it was a signalink senior moment...sri
There is a pinout in the ldg manual...you could ring out the cable.
Allan, the cable came with the tuner, at least mine did a month ago. Watch a YouTube video on setup. I press the tune button on the Z817 and the radio switches to packet, the relays rattle and the green light illuminates steady...I hope.

My FT-818 will not work with the tuner, it does not change mode and power and so the tune cycle fails.? The Baud rate is set correctly.
The tuner works fine without the cable I.e. manually sending a carrier to tune.
I do not know what is at fault, the cable, the ATU or the FT-818

I've gotten into the habit of long pressing the Z817 at every band change. Not sure how or if it matches automatically. Am I missing a key point in operation?

PS / Alarm / Security / Emergency light gel packs are the worse as the assumption is that they are not regularly deep discharged. One or two deep discharges destroys them.
These devices do destroy gel cells that have been discharged, but there's two
ESSENTIAL conditions here that need to be understood as to why.
?
1 - A too deep discharge below about 10.5v without them being re-charged
is the killer. Assumes something like a 12v gel cell.
?
and
?
2 - The crappy inbuilt chargers dont have the current limiting, and the gel cell gets
a what of maybe 1.5 - 2 amps before settling down after about an hour or two.
?
It's too much for the batery chemistry to survive, and should ALWAYS be limited to
1/10th of pack capacity. All it needs is a current limiting resistor, and my experience
of things like UPS's and emergency lights etc has shown that they never bother
to include this vital but utterly essential component.

Please please re-read my advice ;-)

If you don't observe thes rules then you kill the pack, simple.
