I have a key that came with a spare Yaesu FT81x series VFO knob. I've just measured mine at 1.46 mm or 0.0575" AF.
HTH.

Hi Joseph

Is it a hexagonal?

If so I will need a very small allen key.

G3ZCC?

In U.S. we call them set screws and is almost always an "Allen" type. I assume it's a metric size given other 817 hardware is metric.

Hello everyone the VFO tuning control complete with spindle came off and a spring and some other small pieces fell out.

I stripped the 817 down and removed the front and the rotary actuator.

I had a broken front from a u/s 817, I worked out how to get the rubber outer off and I can see a hole, which I assume has a grub screw holding it to the spindle.

The working 817 just needed the nut taken off remove it.

I want to put the complete tuner in the working 817 but dont know what to use to loosen the grub screw.

Can one of you fine ladies or gentlemen help me with the information please.

Thank you

I have the Portable Zero Field Power 3 battery case system for my FT-817ND.? It uses a Bioenno Power 3 Amp Hour battery.? I purchased this early this year and so far my experience has been good.? YMMV.

I also 3d printed a similar one of these a couple of years ago without the BMS as I use an external lipo charger but would go down this route now. It's been very reliable.

I built one of these battery packs a year ago.



Instead of attaching it to the internal power connector, I drilled a hole in the 3D printed cover (allows for the 18650 pack to fit) and added a anderson power pole connector. Charges via powerpoles and connects to the radio via powerpoles. It works like and external battery, that is housed internally.

I opted for this option since I can pick my batteries. I have 3000mah 18650 batteries in there now, and I have not had any issue running out of power when operating portable.

I used to have the parts printed.

I bought my used 817 a couple of years ago with a Windcamp battery and cover already fitted.? It works well, but it is no longer holding charge as long as I would like.

I have opted to switch to 18650s and have ordered this case and charger from eBay:??
18650 battery power bank box case for yaesu FT-817 FT-817ND FT-818 transceiver
??


(and have ordered some 18650s, but as said above the capacity seems a bit of a lottery)

Anyone else using this option?

Steve,
I have had this problem on my FT818 on occasion but not the 817.? I think it just goes stupid for one reason or another and I end up forcing a factory reset to clear everything.? I use it generally everyday for an hour on 2 meters to talk with a friend.? He will report a little noise on my signal and when I look at the display I see the HSWR warning flashing.? I have checked with a dummy load and it still occurs.? A factory reset clears it.? Be sure you have saved memories and such first.

I am VE team Leader at VFW post 3115 Amateur Radio Club, W?VFW.? We have 4 blind hams including the President of the club who also is a Vietnam, vet. We keep one of our repeaters on ALLSTAR -Blind hams Talk group which is active, interesting and has become the most active repeater in the area.

A group in Australia has developed a speech synthesizer for the FT-817 series. I spent over a month gathering parts to build 2 of these. One for my rig and spare parts in case something is defective. Some of it came from China. Best scenario is I'll build 2. I have all the parts sitting here since Christmas.. Everything is an emergency including driving to Orlando to help a stranded friend for a week and tomorrow.. report for jury duty.. Last time that happened, it was a week, no one saw me.. which backs up the repair of my Windom flat top the mast as one end failed in last weeks 55mph high winds.

Here's the full write-up.. It basically makes the FT-817 speak, frequency, band, mode including menu items.


I mentioned it on Blind Hams Talk group and I keep getting emails.. build me one. I see parts to build cost about $30.. You have to get them from various sources. Then they can be put into a external speaker enclosure..

Why I suggest if someone wants to Start a cottage industry, You all ready have a FT-817 to test them, and blind hams don't solder very well. So they are looking for assembled and tested.? I have been building SHARI's for ALLSTAR network and can do it for? under $150 complete.. there is a guy that offers his version called? a clear node .. where he set's up all parameteres for the blind ham and delivers it for $295. They gobble them up... Blind hams can't homebrew or do kits.
Setup of either is about 2-3 hours, depending on how skilled you are. So he's making money.

Anyhow if someone want's to try building them and make a few dollars for the next toy we all need to buy. Let me know. I may even invest. The Chinese have jumped on the N7DCC auto tuner and DL5MAN's uSDX qrp rig.. so there's money to be made. I don't have the time.? Plus there are plenty of guys who would buy here.. Let alone Blind hams...

Larry W8LM..

AAAAAAAAAAAAAAHHHHHHHHH!!!!!!!!!!!!! just dont tell my boss he (VE2DX!) will kill me, list is getting so long.... ;P

I will put it on the list, but I do have a lot to do for a while...? most important are my new CAT62B-Meter/Interface (Now this one your going to love!) for FT-8X7 radios and CT17B-Meter/Interface with 3 ports hub and WILL work with most newer CI-V radios...? these I am hoping for late April early May... Maybe show them off at DEERFIELD hamfest! maybe!?

and new CAT62B-BT, but that is a long way from done still debugging...

Glad it finally got there!

Hi Richard,

Your BT CAT interface works great. Any chance of making a simple dual ACC cable for the FT8x7 series transceivers so we can connect an external ATU and a PC to do CAT at the same time?

Having tried a variety of NiMH internal batts with varying success, I found using the 7 Ah gel cells pictured in Martin's post to be the most reliable for the cost. I always bought used gel cells labeled "alarm pulls" and found capacity at least 6 Ah. Yes, they're heavy and not suitable for backpacking but they power the '817 to 5w for a long time. Ok, I'll admit that I backpacked one up to Big Baldy (Kings Canyon Natl Park, CA). I own 3 of them and have paid from $5 to $10 max. At Dayton some years ago, I bought this charger from batteriesamerica.com: #12BC0500D-1. Its designed for SLA batts only. I even use to charge my 12 lawn mower starter battery.
Recently I purchased a Bienno 9 Ah lithium batter that is the same size as the old 7 Ah gel cell battery. It comes with a charger and it all works very well. It will run a '817 all day and then some. The Bienno being very light is easy to backpack for SOTA excursions.?

Recalling how I had it set up before, that was the reason?I using the front antenna connector for VHF/UHF.

Steve?

We all must remember to remove all non UHF and VHF rted devices such as SWR meters, Power meters, and tuners or amplifiers and antenna switches from the RF path when operating above 54 mhz! (Routing a UHF or 2meter signal through an HF tuner,switch, amplifier, SWR meter, etc. can cause high loss and SWR increase, as wiring in such devices is usually inadequate at 440 mhz.)-Go direct from the radio to your VHF or UHF antenna, amplifier, etc.(or use an external coaxial relay/switch rated for 500 mhz or higher!)

Martin, you can tell the radio to use 5 watts with internal batteries. It defaults to 2.5 but can be changed to full power. It’s in the manual. ?
