Re: Repairing the VR-UNIT of a FT-817ND

 

Please, please, PLEASE, stop sending multi-megabyte pictures as attachments.? Find some better place to put them, or reduce the resolution so that the?
message takes up far less space.? When your message hit my inbox at 3AM, it caused all my email to stop because it filled my mailbox.? I lost multiple subscriptions due to bouncing email, and all the mail traffic from 3AM until 8AM, when I discovered the clot.

Thanks a lot for your suggestions. Confirmed that the 1900 mAH battery pack is now standard for ft-817ND per Yaesu. It is supported by internal charger so convenient. A bit costly though.?

All parts ordered so perhaps by next week plus may have a sitrep on the repair job. Got the right service manual in hand.?

To prevent unevenness you should remove all the old paint that you can. Use a primer before the final coat. Use instructions for doing automotive paint to get a food surface, including wet sanding between coats it may help get a good looking end product.?

Repairing the VR-UNIT of a FT-817ND

 
Edited

Hello FT817 group,

I am in the middle of ordering parts from Yaesu and other suppliers to refubish and repair a FT-817ND. A fellow ham gave this project to me, after it waited 3 years for a resolution, and as far as i can tell (see pics), the VR UNIT needs attention - missing knobs/potentiometers/etc. But I also noticed the exterior top and bottom case scratched a bit. But the unit was provided to me in disassembled condition, so once the parts come for the VR UNIT, I will try to put it all together. #FT-817ND.?

  1. Is there any firmware update needed for the VR UNIT operation/installation?

  2. Is there any diagnostic procedure available to me to figure out if any board is non-functional after re-connection of all sub-assemblies and inital power on?

  3. Is there any firmware update available for this series?

  4. Also: On the call with Yaesu (great service) USA, I was told informally that the FNB-xx series of battery packs for FT-817ND was replaced by?SBR-32MH ? is this true??

    Just wanted to find out where this compatibility is specified before I consider ordering it.?

  5. I was wondering if the Yaesu VR UNIT assembly CB1359001 came with the signal connector J4901 already soldered - or do I have to source that from the current board??

  6. Is there any recommended practice for painting the exterior covers so that it may look a bit more modest? I was actually thinking of getting artistic and painting it a royal bengal tiger stripe pattern, just because I wanted to do that for a long time.

Re: SSB mechanical filter ripple?

 

Thanks Oz, I believe you are correct.? I replaced the mechanical filter with a "null" 10dB 2 kohm impedance attenuator in the SSB filter location (with suitable pin coding as per the actual SSB filter).

The ripple went completely, leaving a low-pass roll-off that tallies almost exactly with a simple LTspice model of the active audio filter that follows the product detector.? That is already down by 3.3dB at 2.5kHz.

All interesting and educational - but now to try and track down why the rig is not presenting the SSB filter with the correct impedance.

Re: SSB mechanical filter ripple?

 

My initial guess? is mismatch to the filter.

What's the pass band look like without the filter installed? Or with another filter installed?

SSB mechanical filter ripple?

 

I've just installed a YF-122s SSB filter in my FT-818, the audio certainly sounds much fuller but looking at the overall RF to audio spectrum there is considerable ripple and slope - amounting to nearly 4dB over 500Hz to 2.5kHz.? I checked the filter separately, correctly terminated, on a VNA and the response is beautifully flat (<0.7dB peak to peak).

I just wondered if anyone else in the group has seen this effect and dug into possible causes?

Many thanks

STOP IT CHUCK!?? I just spit my 2nd cup of iced coffee all over my desk!

All Band, all mode, 100 watts but capable of QRP, because I will be running on battery power and solar panel (180w) a good deal of the time.? I want/need more than the FT-817.? I need as low an RX power consumption as possible.? I need it as small as possible, the trailer is very small.? But the places we can go with it behind the jeep will be awesome!

IC-706 series is out, way too much RX consumption.? I think my best bet is another FT-857D.? But I’m open to others.

The FT857/897 are the basic 100W radios that does cover a lot of bands as the FT991 does (HF/6m/2m/440 and all mode).

But the FT991 is IF DSP allowing of setting up IF filters where the 857/897 requires additional filters you buy and also is useless AF DSP.? The FT991 also does Fusion and has a touch screen making it easier to get to the menus.? The menus in the 857/897 suck, that is to access them.? Also the FT991 being IF DSP, it also uses the DSP for shaping the rcv and xmt signal, lots of filters for adjusting this.

The FT991 is a few notches above the FT857/897 that are more of 2000s radios where FT991 is more modern.

That group are designing yet another amp, much smaller is footprint too and more

much use for the current one I am not sure I would sell mine just to build a newer one.

I think if anything I would keep what I have and I need more power or features I would

go with an FT-991 maybe.

Not doing much of anything for the time being though.

Re: was TX ERR, now FT-817, FT-991A, and MOTA

 

The FT857/897 are the basic 100W radios that does cover a lot of bands as the FT991 does (HF/6m/2m/440 and all mode).

But the FT991 is IF DSP allowing of setting up IF filters where the 857/897 requires additional filters you buy and also is useless AF DSP.? The FT991 also does Fusion and has a touch screen making it easier to get to the menus.? The menus in the 857/897 suck, that is to access them.? Also the FT991 being IF DSP, it also uses the DSP for shaping the rcv and xmt signal, lots of filters for adjusting this.

The FT991 is a few notches above the FT857/897 that are more of 2000s radios where FT991 is more modern.

Hi Marty,

Don't know the FT-857D, but the FT-991A has everything and all reviews say it's great, so I'd feel safe in saying that the FT-991A is a complete and deluxe upgrade for the FT-857A.

Hi Chuck

A question please. Is it safe to say the FT-991A is a good replacement for the FT-857D?

Say size wise and mostly the same but up to date or with more features?

Thanks

Planning to get either a PTT or VOX headset for it.

Very happy with my 2 FT-991As. ?Will do "expeditions" in my minivan sized RV and use nearby repeaters that have 90 mile radius as I search for hobby farms that still raise the Stone Mountain Cannonball watermelons (aka Black Diamond). ?,,,
