In an attempt to clean drawers I have this stuff for sale:
- Yaesu YF-122S original filter (SSB). Like new, w/box. 120�
- New Inrad 500hz filter boards (no filter) for DIY'ers. Easy way is soldering
a 526-8693-010 Collins filter which are available on ebay or similar sites
at various prices, or you can build your own. 2 units, 30� each.
Items are located in Spain, I'd prefer domestic or EU but will ship anywhere at
actual shipping costs.
Will listen sensible offers.
TIA

Re: Tip of power plug stuck in socket
To get the broken tip of the power connector out of the socket I did this trick successfully:
1. Cut a 1" piece of Gorilla tape or gaffer's tape.
2. Roll it into a cylinder approx the same diameter as the barrel plug, with the adhesive side of the tape facing out.
3. Insert the rolled up piece of tape into the socket, making sure the socket pin goes inside the roll of tape. Push it in as far as it will go.
4. Pull it out. The broken plug tip should be stuck to the tape. This might take a few tries.
It is inevitable that this fragile tiny plug will break in your FT-817 power socket. The tape will get it out.
I installed the N0WL Powerpole adapter on the FT-817 after this. Not a permanent mod, and it reliably converts the FT-817 to Powerpole, ruggedly attached to the ground screw.

Re: Tip of power plug stuck in socket
Farren,
I have been successful by adding a little solder to the exposed part of the connector and then soldering a wire to that.? Then you can pull the whole thing out.? I bought these a while back and they are great.?

Very small watchmaker's screwdriver also works.? I managed to lever mine out like that.? Now have PowerPole adapter fitted!

Re: Check out WINDCAMP YAESU FT-817 FT-818 For Anderson PowerPole Adapter Connector to DC Plug on eBay!
I have and use the Windcamp version of this too. You'll note that the old "ground" screw is no longer accessible (which it was on my SotaBeams version that I gave away.) But worse than that, with an FT-818nd, get ready to disconnect the battery pack every time you turn off the radio because if left connected, the Windcamp will flatten the battery pack in about one week. Note that this is a Yaesu Easter Egg and is fairly well acknowledged by now. It affects anything you leave in the DC input socket.

Got the SOTABEAMS version of this.? Works and prevents damaging the FT-817/8 power jack.?
Take care,

Re: Tip of power plug stuck in socket
Heat up a needle then poke into the plastic, when it cools you should be able to pull it back out with the plastic attached. May take a couple of attempts to succeed, but quite a few people have reported success using this method (thankfully I haven’t needed to as many years ago I went to a permanent connection with a powerpole instead). ? ?

Subject: [ft817] Tip of power plug stuck in socket? I recently purchased a used 817 and I just discovered that the yellow plastic tip from a power plug is stuck down at the bottom of the power socket on the radio.? Any suggestions for how to remove that from the socket?
Worst case, is that power socket available so I can replace it?? Got a DigiKey part number??
Thanks!

If the finals are shorted, will the 817 not power up?

Re: FT-817 almost powers up
Today's Update
- I found there is no connection in the power jack? from the outside barrel side (negative) to the trace that runs to the common mode choke (negative side). I've soldered a wire to the jack pad so I can power the rig up on external power.? With that in place...
- When I plug in external power, as before the rig coms up with all segments and icons black, and if I shine a flash light on the LCD I can see it's trying to display the charge status (CHG TIME RMN and a count down timer.
- If I press the PWR-ON,? it tries to boot and shuts off. Removing the power plug and re-inserting takes me back to bullet 1.
If I run on just battery, it tries to boot, and shuts off. Both internal fuses are intact, and I see good battery/line voltage to the display board, and +5v on the display board regulator and the reset chip next to it. Seems like something is dragging it down before it fully boots up.? I am assuming the CPU is good because it can display the charge time. Bill

Re: Help please ... FT817ND not getting power from rear connector, ok on battery
This was exactly the trace I repaired this Tuesday... Looks like I am in a good company

Re: Help please ... FT817ND not getting power from rear connector, ok on battery
I had a strange occurrence with mine. There is a chip cap right near the connector on the pc board that blew up. It took out the trace from the connector. The chip cap was only rated at 16 volts, on the 13.8 volt line.
This doesn't look like enough leeway in voltage to me.
I repaired the pc board trace and put in a chip cap rated at 25 volts.

The DC connector is a definite weak point. There is a very thin PCB track which can fracture. Also, frequently taking the plug out and back in again can loosen the solder joints from the socket to the PCB. I had this problem a while ago. Unless you are REALLY skilled with the iron (which I’m not!!) it’s a job for the professionals. Then when it’s been repaired, fit the rig with the type specific Power Poles. That way, you can disconnect the PPs as often as you like, as the PP connector stays permanently attached. Yaesu UK did mine for a very reasonable price. 73 Ivor G4RJA On 2 Sep 2022, at 08:10, Bryan Nehl <k0emt@...> wrote:

Re: FT-817 almost powers up
Hi
It has been a while since i read about this sort of fault but i do remember someone saying that there is a common mode filter in the power rail at some point and that with a reverse polarity feed and a chassis ground that the negative rail can be taken out. A quick way to check is DC ohms check from the negative lead to the radio chassis.
A long shot but hope it helps

Re: FT-817 almost powers up
Hello,
just my experience from this week.
After a repair and a mod (SEL encoder, and Sotabeam filter) everything was working fine. A few days later I tried to power up the radio and I wasn't working?anymore - no sign of life.? I don't have any internal battery installed so I could check only with external power supply.
I was a little bit puzzled at the problem, because?the main bus voltage was not consistent between measurements.
At the end I was able to track the issue down to a broken trace (the one near the power plug?which?connects the negative of the power plug to the choke filter. So based on where I put the negative lead of my multimeter I could see or not see a voltage. After repairing this track everything went fine and current consumption?is normal.
I still don't know the reason for the broken trace. I could see corrosion due to a precedent repair in the area (probably?power connector replacement and corrosive flux left in the pcb), which was noticeable even on a picture?I took at the radio just before?repair and mod, exactly on the broken trace.
Hope that helps,

If I remove the power and use the battery, the voltage readings seem correct.
In the original post I was measuring from the 817 case to the 13.8 line on the main board and getting 0v (because relative to the DC barrel, they are both 13.8? --? same potential)
