Re: Identifying an FT-817ND versus FT-817
Hi Don,
As far as I know, one of the best ways to identify the ND model
is to check Menu Item #15.
If you have 3 display colors, ie, Blue, Amber, and Violet, then
you have the ND model.
Check this out and see how many display colors you have.

Re: FT817ND servicemanual/ boardlayout
Erlend,
what you should see on pin 1 is the DC input voltage, fed
from a 10Ω, 1/16W resistor. This can only supply 75mA, or
the thermal rating of R1235 will be exceeded. If you are not
seeing 13V or so, then you may be measuring at the wrong pin. The
diagram on page 5 of the user manual is, AFAIK, as seen from
behind the pins of the plug.
There is a more recent version of the service manual to be found
online, though I can't remember quite where I found it.

Hi all.
I'm in need of an schematic and board layout for my
817nd.
The service manual i have managed to source online only
contains revisions 4, 5 and 6. Of Course the area of interest
looks completely different on my board witch is marked with
the number 9.? So I'm guessing that mine is an some what newer
version than the ones in the service manual i managed to find.
The issue I'm having is the voltage output on the ACC
port, for tuners and other accessories. I'm just getting 1,6v
out, with an 13v PSU.? I'm suspecting R1235, but the board in
the service manual layout is completely different from my
board in that area.?
Any help would be appreciated.

Re: Yaesu FT-817 battery pack - Amateur radio tips and how-to guides
The one thing that is being overlooked is it is NOT the anderson power poles that is causing the problem. It is the insertion of a coaxial power plug. It doesn't mater if there is a Anderson power pole connected to the other end or just a extended power lead. It is the insertion of the power plug itself that is tripping the internal switch in the radios power jack. So the answer to the battery drainage problem is NOT to plug anything in the radio power jack if you have experienced the battery drainage problem when storing the radio with internal batteries. Problem solved. Clyde KC7BJE? When I was a child, I thought nap time was punishment. Now it's like a mini-vacation.

Hi Mark,

Probably not worth the
price is repair so maybe some kind soul can
guide me on what to look for. Purchased
December 2006. Stock except for 500 Hz CW
filter.
1. When disconnecting and
reconnecting power, it does a hard reset to
factory defaults
2. After power on and a
couple hours on in receive, it shuts off
3. Tuning on USB and
listening to FT8 on 40, then switch to digital
mode, the frequency on digital shows 6.879 kHz
rather than 7.074 kHz (and I still hear the
FT8). All other modes show correct frequency.
This happens on all bands tested so far.
If it is something simple,
I can try it and fiddle. Nothing to lose. But
at $70 per hour plus shipping to Yaesu, seems
in-economical to look for repair
Anyone have any
suggestions? Thanks
PS not the Power supply, I
have another 817ND sitting right next to it
that works perfectly.

Re: Yaesu FT-817 battery pack - Amateur radio tips and how-to guides
Good afternoon there.
ALL are valid questions. All we need is someone technically capable with
the gear and the time, and an FT-818, to go into it piece by piece and find
out what the real deal is. Perhaps someone has bought the service manual
with the schematics?.
I would almost suspect some sort of power jack switching. I say this
because one could almost assume if an external power plug is inserted it
will be for an A/C mains power supply of some sort. And being powered off
the A/C mains, leaving the display backlighting on would almost make sense.
If this is true, it is yet another strike against the FT-818 for my needs.
I cannot recall ever powering the FT-817ND off any A/C mains power, but I
have often attached various external batteries on extended portable
operations. A few years ago I ran my FT-817ND in a V/UHF contest. I was on
a mountaintop 3,000+ feet (1,000m) above the city, and I ran on
6m-2m-1.25m-70cm-23cm, all @ 5-watts except the 23cm was only 1 watt. I
depleted the two 3600 mAh internal batteries and a single 4600mAh external
battery and was working on a second external battery when I quit the contest
for the night. I just got too cold.
I am also quite unhappy with the 818 power levels. The difference between 5
watts and 6 watts is a joke on the air. In battery life, the difference
between 5 watts and 6 watts is not very funny. But what I would really miss
is the 0.5w setting that the 818 no longer has. This is the best for driving
transverters and enjoying longer battery life while doing so. The average
transverter needing only a few hundred milli-watts to drive to full power,
the 1-watt low power setting on the 818 is just wasteful.
I look forward to seeing how this shakes out. It would be sad indeed if the
FT-818 cannot accept the power pole adapter. It would be sadder still if the
power jack failure situation were not corrected in the FT-818 in addition to
hot having the more robust connections.

A look at the schematic of the FT-817ND shows that the batteries are
isolated from the power connector by a reverse biased diode, and nothing is
connected to the switch part of the power jack so nothing connected to the
power jack, nor the act of inseritng a plug, can discharge the batteries.
There will be a small amount of current drawn by the CPU when the radio is
off, so a small amount of discharge can be expected but, in my experience,
the batteries hold their charge for many weeks.
While power is applied to the finals 24/7, they are biased off in this
state, so don't draw standing current. Most rigs do this, because the finals
need the whole supply voltage at considerable current, and adding a
switching element in line can cause voltage drop and is unnecessary (the
final transistors switch just fine, after all!).
What we don't know, is how things have changed in the FT818. I can't find a
schematic / service manual online and don't have one to experiment with.
Maybe they utilise the switch part of the power jack to detect external
power, as opposed to sensing the voltage at the power jack input? Perhaps
triggering this switch (by insertion of a powerpole adaptor) causes the
standby current consumption to increase regardless of what, if anything, is
actually connected upstream?

Re: Yaesu FT-817 battery pack - Amateur radio tips and how-to guides
AGREED!
And when the last two of my 3600 mAh internal battery is dead and gone, the Windcamp is the next best, and that is what I’ll end up with. But for the last 150 or so portable operations I have done, just connecting and disconnecting the battery has worked well enough for me.

Howdy Steve.
I have connected and disconnected that connector hundreds of times, I am just careful to not damage it.
From your description, it is obvious that some parts of the FT-818 are very much different from the FT-817ND. The FT-817 and FT-817ND have been around for so long just about everything is known about it. The FT-818 is so new, and a lot of assumptions have been made about it. Perhaps wrongly so.
I hope they also changed the final connection. My experience has been that leaving the battery connected with the radio off and disconnected from external power will drain the battery slowly through the final connection. Furthermore, leaving the battery connected and the radio on external power (radio turned on or off) will trickle-charge the battery, but this also seems to hasten battery failure by overcharging.
So with the FT-817, you're wrong if you do and you're wrong if you don't. I just disconnect the battery when the radio gets stored, and I have no issues.
It will be interesting indeed to see what shakes out of this mess. And I'm more happy than ever that I did not trade off my two FT-817NDs to get the "NEW" radio. It would not have been worth it.

Subject: [FT817] Re: Yaesu FT-817 battery pack - Amateur radio tips and how-to guides
I do not wish to disconnect that tiny plug over and over. I don't believe it was ever conceived of as being used in that fashion?
Some background is in order; with my FT818nd I discovered fairly early on that the display backlight did not time out irrespective of the relevant menu setting. It became apparent that once the PowerPole adapter was removed, the time out suddenly began to work. I thought that was that and didn't make the connection with the excessive battery draw I was experiencing. Around late January I realised that the adapter was causing the battery depletion too.
I have tried numerous non-energised power supplies and the only one that did not affect the backlight was the supplied Yaesu one. No surprise there BUT the Yaesu supplied 12V lead did affect the backlight function so go figure. Another guy tried a 150 Ohms resistor across the 3D printed adapter which "Cured" the "fault", but I didn't want to leave such a low value resistor across the DC socket. The power supplies that did not prevent the backlight time out all exhibited a high resistance across their radio end connectors. I am thinking that a dummy PowerPole plug with a (let's say) 22K resistor across might work and maybe prevent the battery depletion too since I suspect they are related. I have yet to try it.
There is a web page somewhere where someone has posted 817 pictures next to 818 pictures and there are one or two component alterations or additions around the DC socket connections on the board.
I reckon that the radio must be sensing the physical presence of a coaxial plug by way of a switching jack socket, but perhaps it may also be looking for some value of V, R, C (or all three) across that socket as well.
I think I've probably over stepped the mark on a forum for what Yaesu would have us believe is a "different" radio, but I cannot be the only 818 owner that lurks here watching out for and benefitting from the collected wisdom, experience and recorded information? The PowerPole adapter is a great idea but I just wanted to highlight a caveat for prospective purchasers. I believe that's what these forums are for.

Re: Yaesu FT-817 battery pack - Amateur radio tips and how-to guides
I believe it's the presence of a coaxial plug in the socket alone. There is no criticism of the adapter. Just that the 3D adapter is designed to be left in-situ. While it will preveng the drain, neither a battery isolating switch nor unplugging the battery (which is essentially the same thing) will allow the back light time out to function *on an FT818* while the adapter is screwed on. The gradual drain of a connected battery in the FT817 is not related to my experience of total depletion in around two weeks. I never imtended any criticism of the adapter which was designed for the FT817, but folks considering the purchase of one for an FT818 need to be made aware of this so they can decide whether they can live with it.
All best,
Steve, G4VRR.
