Look at this guy with no experience trying to do this. Que the Benny Hill music.

Nice job. Well done! Thanks for sharing

Hello, I'm in the USA and was wondering where to buy the optional roofing filters. And what website do I find the instructions? Thanks in advance.

Why in the world didn't Yaesu just install the dang filters in the first place....?

My filters have just arrived for my FTDX101MP, I am in the UK and they are readily available. Hopefully will get it all done promptly. 73 edit: Fitted them today, the 1200hz filters are more useful than I had expected. Good for digging out noisy SSB. The miniature coaxial connectors are the most fiddly part of the job. 73

Howard, thanks for the great tutorial! I added the 300 Hz CW crystal filters to both receivers of my FT-DX101D. The filters are offered here in Germany by a well-known dealer, but no installation instructions are included. Therefore your video was very appreciated! The modification went smoothly, however you should already have experience with such circuit boards. If you do a lot of CW and DX, the narrow filters are worth the investment. 73 de Georg, DL5NO

Can you make a video of how this filter actually works when receiving signals. Comparison of 1.2kHz to 3kHz filters. I'm thinking about installing an optional 1.2kHz filter, but I don't know if it makes sense

You'd think after watching the video of the factory assembly of this rig that the so-called TLC would have avoided all that seems to be vexing this radio. So much for using "quality parts." You wonder!

Looks simple - Am I the last on the planet to use Static discharge mats and ESD precautions ?

Yaesu USA specifies all option roofing filters as 'Factory Install Only' and won't sell by itself.

Good info. Thans. I need to replaced ch. B AF/RF knob that I bumped and damaged. I know I can do it. Looks like that knob is soldered to the mini pcb. Either way your video shows how to access the front panel. Just one little bump and the know got bent.

I have the same problem with mine, but l am not very good at doing there’s sort of work, so am just going to leave it, knowing my luck l would damage something else when trying to do the repair, thanks for the video very interesting, de M6JNZ

Thanks so much for taking the your time to make this video :)

Wow lovely radio and interesting repair thanks for taking the time to make the video.

can you help me with a part number for this

Nice video.

I wonder if that's the same craptastic encoder that's used in the FT-847?

I don't suppose you have a part number for the encoder, do you?

I don't care how good or bad the encoders are, between dust and oxidation they are just a cheap way out. Convert it to an optical and be done with it. No more problems. My 590 is less than 2 years old and it started about 6 months ago. You never showed the inside of the ALPS encoder?

I just replaced one on my ts-590 with an optical encoder. Had to make up some circuitry but works much better and don't have to worry about it going south. Rig is less than 2 years old.

Hi Howard, great video, thanks for taking the time to share this critical procedure. Hope I'll never have to do mine. 73 Pascal VA2PV

thankyou Howard most helpful 73 Robert G3RCE

How long is the original shaft? how much did you cut off the replacement? The original encoder looks has a 6 pin . the replacement look like 8 pin. i am not sure hi

Thanks for making this video. I just had to replace the NR pot and face plate for the 990S and this video helped in getting started. Be sure to take a close look at each slide in cable. The smaller ones just slide in with minimal force. The larger cables have two types of holding clips. The black ones slide up for release while the others open out. Be sure to open the larger clips before sliding them in or out. Take the time to understand which one your trying to disconnect. Having to replace one of the LCD screens is straight forward and predictable. Aluminum colored screws connect to the face plate. Black screws connect to metal frame and not the face plate directly. Small 3.5 glass in front of smaller lcd is held on with double sided tape and removable from front. I used East Coast Kenwood Parts and received parts in 2 weeks from Kenwood Japan. 73, W8VI

nice video.. good knowledge to know, thanks for posting.. 73s AA1US..

Having the same issue on my ts990, a little less than one year old. Also thinking of changing the part myself, but KW insist on haven the radio sent in. Hard to get the part, Howard?

I once had a very hellish nightmare that went just like this video.

Isn't that what ham radio is supposed to be about ? :) , in any electronic product there is always opportunity for failure of a component .

$10000 radio and you still have to take it appart and fix it.

I am considering a purchase of a TS-990. I am really on the fence about it. It appears that there is some light corrosion of the right side of the chassis. I noticed that when you were loosening the screws on the right side to fold down the front panel. Do you remember seeing that or was it something else? Otherwise, how do you like the rig.

Very strange, i had the TS-570DG with the same encoder problem. I fixed it with an original part. Amazing that Kenwood still did not use better quality parts. They really should learn from the old problems and get rid of it. Great video and for sure a great TRX.

Impressive and well explained video. A small tip: if filming a subject (radio) try to trow the light from the front and not from your back as you trow a lot of shadow on the subject making it dark.
