FTDX101D and FTDX101MP Roofing Filter Installation

[@GeorgEinfalt]

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

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

can you give me the vendor you purchased from? Thanks

[@g0fvt]

@@theVizitor2012 the filters were all purchased from LAMCO I fitted the 300Hz CW filter for the sub receiver at the same time as I fitted the 1200Hz filters. I hope not to see the inside of this radio for a very long time now! 73

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

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

Yes.

Boards are safe to handle as every IC is "usually"" terminated when in circuit however it's never a bad idea .

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

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.

[@jonsuehiro5200]

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

[@jamesseaman2950]

You can beat the system by ordering the filters from a Yaesu dealer overseas.

[@howardrosen5573]

Yes, order from a European or other overseas dealer . Yaesu USA has strange policies sometimes . 73 VE2AED

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