- This video shows how to install the Elecraft KXFL3 Roofing Filter in the KX3 transceiver. It shows the physical installation along with the software alignment / sideband nulling process.

I don't own and can't afford an Elecraft, but I watched the whole thing anyway. New W2AEW is always welcome on a Saturday night!
This reminded me that I wanted to readjust my roofing filter settings now that I have an X3G signal generator, which worked great!
Great instruction - I read the manual many times but never really got it 👍
Alan your clear, concise videos coupled with your even tone of voice makes the viewer feel like “hey I can do that”! Very much appreciated as always. 73
That alignment was not as complicated as I thought it would be.
Great video. thanks
I run my KX3 and KXPA every Field Day. As you learn the rig you find it is better than the size lets on. The cool thing about my rig is that it belonged to a trade school electronics teacher before he passed.
Good content.
When I bought my KX3 more than 10 years ago, it was not an available option. I bought the filter kit last year and last week I told Alan I was going to be in town and asked if he would mind installing the filter for me. Of course, he said “Yes” and I dropped the radio off Friday and he returned it the next day (Saturday) at the wonderful W2QW hamfest in Piscataway, NJ. Thank you, Alan, for being such a good friend. Great video, as always, and hope you get a million Likes! 73 DE N2GJ
This is so welcome that I'm going back and doing mine again Alan. Many thanks for this. I found the Elecraft installation sheet a bit problematic in trying to keep focus on what stage I was working on due to the repetitive nature of the steps. Also, I don't recall many of the adjustments you made. At the time, this led to apprehension as to whether the job was carried out properly. Also, Fred Cady's book intimated that it was a per band setting which also puzzled me because the filter is at audio frequency. Many thanks again Sir.
Excellent How-To video!!
Good to see you yesterday! Gerry has himself a nice rig!
Great tutorial!
You are the master Alan.
Glad I bought it already installed ;-)
Your buddy has a great friend Alan! 73 - Dino KLØS
He sure does! Alan has made a few tutorials while repairing my stuff over the years. Best of all, he’s a GREAT TEACHER and overall good guy! Thanks Alan! 73 de N2GJ
@@N2GJ Gerry - did you notice the photo of your tattoo at the beginning of the video?
It is a nice device, but man I would need to study for a year to operate all the buttons and menu options 😂. And then when finished, start all over again because I probably forgot half of it 🤨
Excellent tutorial!
TSG 4106A. Nice reference!
Am I old-school if I would feel better if the knobs were shaped like little screwdrivers? :)
Excellent video sir. I need to retune my KX3 and the roofing filter I installed in it many years ago but never completed the alignment procedure as shown in your video. I too have a signal generator, but I am not certain if it must generate an RF signal or if a sine out would be sufficient to o the tuning. I have been trying to justify buying or building an RF signal gen so .... hmmmm . Thank you for posting this video.
The procedure specifies a test signal that is in the 14MHz region, and between -73 and -33dBm.
@@w2aew sounds like a very good excuse for me to buy a better signal generator … thank you very much. Any suggestions on a generator to buy??
@@michaeldavidheit The tricky part is getting something that has an adjustable output that is suitable for testing receivers. Many inexpensive siggens won't do that. If your needs are primarily testing HF gear, then a more "purpose built" unit like the Elecraft XG3 is a very nice option: elecraft.com/collections/test-equipment/products/xg3
👍
Nice informative video. I think most users don't have access to an advanced signal generator and will have to use the internal referanse you briefly talked about. Could to please make a short video about using that? Doesn't have to be long as this one. Just the steps you skipped.
I wish I could, but the rig is back in my friend’s hands and he’s returning to his home in NM.
Show 👏👏👏
This episode was clearly in esoteric territory for me :) After a bit of research, I found out a roofing filter is basically a narrow(er) bandpass filter in a radio's IF circuitry... but, pfew, not being a HAM made me scratch my head there for a minute. Aha. Anyway your short concise videos, Alan, are always a pleasure to watch. I did read somewhere roofing filters should be used with an IF frequency ranging between 9 and 11 MHz. Is this true and if so what would be the reason? Efficiency?

OMG! I considiered doing this but wasn't sure if it would help significantly with SSB here in the Canadian wilderness (not much QRM!) But I am bookmarking this video in case....
BTW I just ordered a 'tiny Spectrum analyzer TinySA' Only $67Cdn now on Ali. What do you think of it? I already have a NanoVNA.

I picked up a TinySA a few weeks ago at a hamfest, but haven't really had a chance to use it much yet - so the jury is still out...
@@w2aew IMSAI Guy found out some things about it: attenuation! ua-cam.com/video/VjqbMDNlCBs/v-deo.html It's a three-parter.
Thank you. N0QFT

WHEW!!!
Hi, I like your videos very much. We would love to have the opportunity to have our products on your channel. How can I contact you?

Needs one more step: Step #0: turn off key-beep ;) de oh2gqc
It probably has that feature - I just didn't search through the menu to find it. ;-)
