Re: technical standard certification number
Hello Emilio
The original poster did not have any certification certificate information at all for the FT-817ND they intended to use in Japan. I was hoping that copies of the UK version, which along with the EU standards information contains some contact details for Yaesu
might be of some use to them, although it was not clear if the transceiver in question was a Japanese version.
I did try and look further for Denis but there did not seem possible to access the Japanese certification from the websites I looked at.
Unfortunately, as you say if the transceiver is a non-Japanese version it might indeed mean getting the thing certified. To be honest it would probably be cheaper to buy a Japanese one to use in the country rather than bringing one for visits if this indeed
the case.

Hi Kevin,
Is your FT-817nd a Japanese model? If so, is printed on the model/serial label in the radio
Particular for FT-817, the number may vary if was manufacturer before Nov 2007
If your radio isn't a Japanese model, then you will need to request the certification due to the fact they may transmit outside Japanese band plan or don't complain the spurs levels here
They charge for that (4,000-5,000 yen i think) and no guarantee you pass
Of course if you buy a Japanese model, Yaesu already apply for certification before selling it

Re: technical standard certification number
Hello Denis
I have attached the two certificates of conformity that I received with my FT-817ND, hope that they have the information you are looking for.
Regarding the address of Yaesu, they changed there name to Vertex Standard co, although it looks like Motorola might be involved now.
The email address I could find is listed below

technical standard certification number
Hello members
I have the opportunity to visit Japan on a fairly frequent basis over the next few years and I am thinking of applying for a Japanese callsign.?? Most of the hurdles I think I can overcome.
However in order to apply for said license I need to supply to the JARL, a technical?standard certification number for my FT 817 nd?? A thorough search of the operator manual that came with the radio fails to mention any such number.?? If I cannot supply the number then I will incur a cost to have the radio tested and certified but being made in Japan, there should logically be a manufacturer's document in existence.
Does anyone know the email contact details for Yaesu in Japan please? ? An email sent to their UK office has gone unanswered so far.
Thanks in advance

Re: No transmit function on 2M
Yes I know what?you mean, But when a radio has no power output on 2m ,I think the seller did know, Also sometimes you see things for sale ,and the seller said it is working as it?should as it lights up when powered up,
The last thing I got of eBay was a datong FL3 audio filter, and he said it worked Last time he used it years ago, it is very clean, yes it is 40+ years old, And guess what, it doesn't work, so I will fix this, Yes I did buy it as is, so I did leave feedback, I should have none, but I do like fixing electronics,?

You have a choice: take the chance or upgrade to currently produced
radio with decent factory parts availability.
I had a old parts ft817 so I removed it from there
If affordable, it's nice to have a parts department carcass or two
from which to liberate parts. I have a number of HW-8s serving in
that capacity.
I am getting fed up getting things from eBay And
the seller's saying it was all working,
Not to cover for unethical sellers, but modern day, 160M-70cm
mulit-mode rigs are complex little beasts - which makes thorough
check outs or spec verification challenging at best.

Re: No transmit function on 2M
Yes but I still can't help myself trying to fix them instead of sending them back to the seller, All the best, Dave 2E0DMB?
yes this is often the case when buying second hand, lots of hidden defects..73's

Good evening 2E0DMB
Well in the end it was D3003. I replaced it and it started again.
To disassemble the PA board, it is better to first disassemble the main unit because there are pins connecting the two cards.
For reassembly you must first dismantle the main unit, this is mandatory. (otherwise impossible to connect the pins)
for the diode format it is SOT-323
I put a BAS316 in and it works great.

Re: No transmit function on 2M
Hi the bad thing with mine was I had just got it from eBay, obviously the seller said it was in perfect condition, I could have sent it back, under eBays contract, but it was a good price with a tuner and lipo battery, I did leave him bad feedback, Let me how you get on with it, Dave 2E0DMB?

Good Luck, Dave 2E0DMB
so on Pin 8 of Q3003 on the PA Unit is a voltage called V-TX that
switches the output of the PA FINAL thru to the 2 Meter Low Pass Filter.
There it passes thru the Relay RL3001 which for 2Meter is closed from the
moving contact to the Normally Closed (Black) contact which passes the TX
energy on to the Diode D3003 an HSU277 ( Pin Diode ) and from there on to
the ?front or rear Antenna select RL3015.
Other than that, there is another Diode D3005, that enjoys going bad and it
can also cause the problem you are having.
These are both on the bottom (B side) of the PCB.? This diode turns on to
protect the RX when TXing.? This is turned on from pin 4 on the Q3003.

Re: No transmit function on 2M
Hello and thank you for your response. I studied the schematic this morning and came to the same conclusion, it can only be D3003 or D3005. I located them on the layout and I have to remove the plate to see because of the interior side. I will tell you 73's SEB

Re: No transmit function on 2M

Hi John,
You are after rather more power than I am, but because I am walking, the amount of time for the panels to be out of the pack and charging the radio is very limited. (1hr every second day)
It is actually challenging to get panels light enough to be better than carrying more batteries!
The '817 has 3x18650 cells.(149g) The panel is 184g, and actually delivers 12V 1A in direct sun. They are compatible with directly charging 3x LiIon cells with no charge electronics (The BMS will protect against overcharge and the zener protects the radio from overvoltage)
I have used powerfilm panels for work projects a decade ago, but the output is so low they don't charge the battery a useful amount in the time available. (They also seemed to be optimistically specd.)
However I thought I would look at powerfilm again. Using a needs 14 panels, and 5x the area of what I have above. i.e it will be a 1.25m by 270mm area of mylar film.
Weight will be : 5.9*14=82g for the power film. This is a bunch of them so at a minimum we should stick them to some thin nylon. So PF panels with adhesive are 8g, non sil nylon is 50g/m, wires plugs etc 30g
8*14 + 50*0.4 +30g = 129g
So a bit lighter than what I have. From my point of view they are infeasibly large for the power I need given it is often in windy conditions. Again my requirement is driven by only getting one hour of direct sun every two days. If you got to deploy your panels for 4 hours every day it would be a totally different story.
The digikey price of USD547 is a bit prohibitive too...

Re: Loosening tight screws
Hi this post reminded me that I needed some jis drivers, as I work on radios, Also have yaesu/ICOM /and Kenwood radios, when I worked on my ICOM ic-7000 I fitted new screws as they are very week, and did not use jis screwdriver ?, I got them delivered from Amazon today, just over a ?10 for a 4pc set of drivers, Dave 2E0DMB?

Another trick (other than using the correct JIS driver of course) is to give the screw a slight nip in the clockwise (tightening) direction prior to trying to extract it. ? 73….Eric VK2VE. ? ? I finally decided to attach the side rails that came with my Portable Zero Pack to my 817nd.? The two screws on either side are so tight I can only barely loosen one of them.?

Are you looking for specifically folding/portable? There are plenty of small/affordable panels available. Try to avoid amorphic unless it's a newer tech. You tend to get much better power per inch out of bi-crystalline or mono-crystalline, even better with CIGS.? I've had good luck watching the local Craigslist or Faecesbook?marketplace. But I also pick them up occasionally on amazon when I can catch a sale.? Eco-Worthy, Renogy, Allto, Future Solar, NewPowa are a few I've gotten. I used to buy Instapark but I don't think they make them anymore. More important than the panels is a good regulator. There's a local mom-and-pop here in Michigan makes great little MPPT regulators (DIY Solar For U), But renogy has a number of PWM and MPPT options available that are reasonably affordable and more reliable than China-no-name. Surprisingly, I've heard really good things about a new little one I just got for basic PWM setup. You see them all over amazon, ebay and aliexpress from multiple sellers. Seems the newest iteration is the 6v/12v 10a version. Here's just one example:?? (you won't get as good of charge rate as you would with a more expensive MPPT controller, but they seem to work pretty good)? Although there is one drawback that I find to be a plus. They have load monitoring and shut down at about 10.5v on the load output. (you can always connect straight to the power source if you want to risk draining a battery lower - these were made for outdoor water pumps for things like fountains, simple plant watering, hydroponic stuff, etc)? They turn back on again when the battery is back to about 12.5v There are some simple, 'in-line' MPPTs that are getting good ratings. I picked up one of these for my RV? but I'm curious about this one also:?? Those don't contain any 'load' output so they won't do any load monitoring for you.
For stuff more elaborate, the low-end entry points for good regulators are Renogy and Victron if you want any kind of power monitoring. These are nice because they have addons which make monitoring wireless (bluetooth) capable but they are still affordable. (although they ream you on the bluetooth addon) . They both seem to make PWM and MPPT versions in multiple amperage ratings.
Next is good power packs or batteries. If going lithium, I recommend LiFePO4 as it will be less prone to 'kaboom' of large lithium poly or lithium ion packs and will recharge much longer. The power per cell is lower, but you usually get more power on their 12v equivalent. (lipo/lion are 3.7 and usually chain 3 cells for 11.1v, lifepo4 are 3.2v and usually chain 4 cells for 12.8v).? On lithiums, try to find cells/packs that have a built in power monitoring / charge protection and that have a good rating.? Otherwise, a good AGM or gel cell lead acid can't be beat for reliability. I have no experience with thiis one, but I just ran into it the other day and I'm curious. They're large, single-cell LiFePO4 but apparently designed so they can be chained in series or parallel (e.g. get 4 of them for a 12v source and connect?+->- on the bridges between - even on LiFePo4 I'd recommend some kind of air spacer between or even a heatsink to keep heat even when charging). Like I say, I have no experience with them but the store seems to have good reviews:? SW
Hi all,
? ?I'm considering a solar panel purchase for portable qrp. Many on the web have sketchy, ambiguous, or contradictory specs. Any guidance would be appreciated. Tnx.?

Re: Loosening tight screws
Hot soldering iron tip pressed into the screw can work too, if you need good localization of heat.
