Glad to hear it! I have been playing with both radios since installing the kits and have had similar results. It seems to have improved a few things on the radios. However I am still tweaking everything. Thanks you for watching and for the comment. 73!!
I'm really enjoying your vids! The ham community information pool has grown a lot in the last 10 years. When I was hunting rfi it was crappy cables letting rfi In to my audio. I had to spend some money on quality shielded cables and I eventually got it all. I'm putting my shack back together and hanging antennas again so I hope to work you sometime! Keep up the good work! 73
Thank you! I think UA-cam is the future of learning about Ham Radio for anyone who may not have access to a club or an elmer otherwise. Glad you were able to find and fix your RFI issues! Always better when that is under control and eliminated. Maybe we'll catch one another on the air sometime! I am also on FT8 on 20 and 40 quite a bit. Thanks for watching and for the comment! 73!
Hi..was just browsing the UA-cam, your channel popped in, really like the stuff so straight away subscribed it.. What I have noticed your S meter was pretty jerky before installing the kit and afterwards it became stable with atleast 1 S down in noise, so I think definitely the kit has worked. Keep the good stuff coming and congratulations for making such a nice channel..TNX
Thank you for the comment. I am still chasing other items around the house that may be causing the RFI issues. I have a few more tests to run, but the kit definitely helped out now that I have had time off camera to deal with it in more detail. Thanks for watching. 73!!
To those who 'Suspected' line noise on their recievers i strongly suggest cutting power to every in home device except your radio. Compare noise floor screenshots or recordings made vs all devices on. If a significant difference occurs turn thing on one by on until the culprit is identified. Maybe relocating somthing protable or to another outlet fixes your issue. This may allow you to spend your radio budget for things you really need. Another bit of advice for 'Non-Techies' in Amature Radio (oxymoron?), get advice from Techies in a technical endeavour, like an experieced Elmer. An good Elmer will help you get where you want to be much quicker & with less expense.
Just a thought...Try shortning the power supply cables to each radio, from the dc power supply. You only need about 3 ft, or so! I did and it reduced the RFI a lot! Also, continue using the Palomar kits! Also, try a line isolator on your coax, at the transceiver! Good luck!!
I have yet to set up my HF shack. It's all still in the box and will be there until I can get some help installing my BBTD whole roof antenna (and HFlink Bonnie Crystal design) , plus I test for General in 6 weeks. I have window AC units (4) and a solar array on the roof over my ham room. Am I doomed before I start. I like the kits and that may be the solution if I have problems. Love your videos. I ordered my balun and terminating resistor for the antenna from Palomar as I liked their reputation. Oh, I will be setting up a G90.
Hey best of luck on passing your General in the next few weeks. I would do an RFI sweep and see if your solar array is emitting any RFI. If so, the company that installed it will have to come out and fix that issue free of charge. If you have issues, call up the ARRL's RFI division and get help from them. The stuff from Palomar will help as well. I hope you end up with a smooth setup so you can enjoy your shack and HF once you pass your exams! Thanks for watching and for the comment. 73!
man thats a nasty looking band scope. Even after the things are put on. I thought I had bad noise you definitely got me beat. I promise to never complain again after seeing yours LOL :)
I went back and added 240/43 toroids to the power cords on the two fridges that are in the room as well and that seems to have helped a bit. Chasing RFI around a house sucks...LOL Thanks for watching. 73!
Keep in mind different RFI can affect different bands differently. What is causing noise in 20 meters may not, or maybe will, be causing trouble at 10 meters or 80. Knowing if the kit is working optimally requires a run through of the bands, a good crawl one night could reveal more advantages of the kit. The other part is, if your noise floor is high enough all the time, it is hard to hear if you are killing weaker noises. If you are out in electrically quiet areas far away from electrical noise, you can get the noise floor extremely quiet. If your noise floor in a city is, say 4-5 S units, and you kill hash or other noises at say, 3-4 S units, you will never know that you made an improvement because it was too noisy to hear the noise in the first place! The noise you killed may have been drowned out... by other noise. When you get the noise floor extremely low in general, you can hear virtually everything. And at that stage, every little noise killer is useful and appreciated. The best RFI killer is probably putting ferrites on the coax, or using a 1:1 choke. The exterior of the coax is an antenna for garbage, and it will bring it into the shack and radio, and it will potentially make your transmit more dirty. Palomar's products there are potentially far more effective and useful than the simple radio wire choke kit.
Agree 100%. I tried the different bands at various times of day and night and discovered that in fact due to propagation and such, it varied throughout the day. So far over the past few days since I installed the Palomar kit I have been seeing an improvement, so at least I didn't waste my money on it...LOL Thanks for the tip and the comment. I appreciate the feedback. 73!!
I agree with every little bit helps... In the 1970's I installed a 20M Ten Tec in my car for the long trek to WSMR every day operating on 20M. At first, the ignition noise was horrible. I had solid copper spark plug wires (I put them on...) so I changed them back to radio-resistance wires which is what all normal cars have even 50 years ago... then I had just as bad alternator whine - but I couldn't hear it for the initial ignition noise. Don't remember exactly how I fixed that but I did and then all was good. What appears to be only one problem may be many buried under each other. Thanks for the video 73
The 'brute force' method for reducing DX shack and general house electrical RF field noise getting into the DX antenna, is to physically move the antenna as far as practical away from the house and street powerline poles. In my case, that meant positioning the high HF / low VHF antenna near my backyard fence line. At approximately 100 feet distance separation, this resulted in a dramatic drop in RFI. So much so that there was no audible SNR difference between all DX shack PCs and modems switched on verses all off. I now know from experience that mounting DX antennas on the house roof will generally degrade weak SNR. Inverse square law provides exponential decrease in RFI as a function of shack to DX antenna separation. This partly explains why the rural and semi-rural 'Big Gun' ham antenna farm installations can hear extremely low level signals that almost everyone else can't.
That is some very interesting information! Thank you so much for sharing. I have resolved the RFI within my house, but still dealing with external RFI but working on a resolution now. Thanks for the comment and for watching. 73!
The RFI tends to be stronger on lower frequencies. I have a FM broadcast FM Yagi on my house roof that receives RFI from the monitoring room. A individually switched AC power board is useful to conduct RFI gear isolation tests. Hopefully it is something simple like a switch mode AC/DC power supply. But your UA-cam video suggestions are also helpful for people that have their receiving antennas near the house. 73.
Hi Scot - I have the same with my 991a - I also have a Xiegu G90 which I use when out driving ect.. I think the problem is the 991a, is a true shack in a box rig and falls under the title of "jack of all trades but master of none" don't get me wrong the 991a is lovely on 2m & 70cm. but when it comes to HF the G90 wipes the floor with it, even sat next to each other in the shack If you ever get the chance to run a G90 you will understand. Anyway bud.. cracking video and looking forward to your next one!!
I like my 991A, but have found the exact same things as issues. My 7300 picks up stuff that the 991 never hears. That video is coming up son! Thank you for the comment and for watching. Glad you like the content! Cheers & 73!
I pretty much did the same, however I think there is something in the neighborhood causing issues like a solar panel array on a house or something. I am still hunting it down. Thanks for the comment and suggestion..73!
I checked those as well when i first noticed the issue. I haven't found any localized problems from my house...it is all external at this point. Thanks for watching and for the comment. 73!!
@ HAM Radio For Non-Techies the mix 31ferrite cores is best. you will need to put them on you freezer power & you computer power cords. the power supply from your computer and you monitor power plug and computer speaker power plug. they add a lot of RF noise to your radios. you can get the on amazon in all sizes to. get all mix 31. example, I turned my comp speakers off and a hum and s units disappeared from my radio, tune speakers back on and hum and s units return to my radio. so I took a mix 31 snap on core and wrapped it around power cord to the speakers about ten times and turned the speakers back on and no hum and s units gone. the computer needed one to. any wall wart like cell phone chargers will cause it to. seem the switching little power supply in them have no RF filtering because there built cheap at a low cost. so any thing on you radios power circuit might need them. I use a linear power supply for my radio. these kind of supply's don't need RF filtering or the old bigger wall warts are made the same way. iron core cost more than switching power supply's. Also LED lights causes RF
Thank you for reaching out. Actually since that show was shot, I have tackled that issue and everything in the house is wrapped in ferrites now. What I found out afterwards is that a nearby neighbor has a solar panel farm on his roof and that is the source of my RFI now. It makes using HF at my QTH nearly impossible except for the occasional FT8 I get to enjoy at night. I reached out to the ARRL's "RFI" department about 6 months ago fully explaining my issue with images and everything and they didn't feel the need to address nor acknowledge my request for help, so that left a bitter taste in my mouth that I will remember when it is time to pay by dues to my ARRL membership. Thank you for the recommendations and wisdom. Thanks for watching! 73
If you are running off a clean quality battery like the ones I use there will be no RFI from the battery. Many times other external things around your house can cause RFI like appliances and LED lights or wall chargers. As I show in the video, you can use tools to detect RFI. I hope this helps. Thanks for watching and for the comment. 73!
I would assume to apply ferrites until you no longer see any RFI or noise. If that is one, great...but it may require more to see the result you want. I hope this helps. Thanks for watching and for the comment. 73!
How would one block RFI that can be heard in the wall around an EMF source or power outlet? It's a known phenomenon, but I haven't found a solution for blocking it out.
There is an online retailer called Palomar Engineering. They sell RFI kits that may help. I would suggest calling them up and speaking with someone about your situation and see what they recommend. They are a very reputable company ands their products are fantastic. I hope this helps. Thanks for the comment and for watching. 73!! palomar-engineers.com/rfiemi-solutions/
Doesn't look any different to me. I think your noise is coming in through the antenna. If the fridge is making noise I'd get rid of it. Have you tried the QRM Eliminator?
I have RFI kits on all my radios. The Problem is coming from a neighbor with solar panels. Still dealing with it with them today. Thanks for watching and for the comment. 73!
you may want to add ferrites to your tv cables and your radio and see if that helps. Palomar Engineering probably has a ferrite kit to help with that as well. Thanks for watching and for the comment. 73!
I know it "should", however I am not confident enough in my skill level to run wire to a dedicated breaker in the box and digging holes in the walls would irritate the wife...lol Thanks for the tip! 73!
I got the basic kit for my 991a, I will guess I can buy the other piece that hooks directly to the radio. When I brought the radio the regular kit came up so I got that, might have got the deluxe if I did more research. Just wondering if you were to take the coax filter for the 991a and put it behind you antenna selector so both radios will be covered, something to think about and maybe try, if it works you have two radios covered with one device
That's not a bad idea, although I would research more about the unit and make sure that it would work in that configuration. Honestly I don't see why it wouldn't. I looked around a bit on the site before I made my purchase and discovered they had a "deluxe" version. i think most could get away with the regular version and be perfectly fine. Thanks for the comment and for watching. 73!
@@HR4NT I just went on and see I can buy that price separate like I thought. My gut tells me as long as the filter is in line it will work. I think they suggest it go straight into radio because now there isn’t any other coax to worry about
That may be possible. You can contact Palomar Engineering and see if they have a kit for that particular radio. I hope this helps! Thanks for watching and for the comment. 73!
The parts they give you are based on how many and what type wires you have in each radio. The toroids they give as well as the ferrite enclosures are exactly the same for both radios. The only difference I can identify is the quantity. Thanks you for the question. Hope my answer helped. Thanks for watching. 73!
Hello Scott I just received my 991a. What did you do to do digital modes, Ft8. The gray matter is shot on this end. Looking for some short cuts. Tnxs KQ4CD Paul
For doing FT8 with the 991 you will need the usb cable for the 991 that will go into your computer. You will want to get a copy of WSJTx and i like to use Grid Mapper in conjunction with it to see where my signal is going when doing FT8. That was really all there was to it. There are some configurations in WSJTx that you will need to do to make it work. ALSO, VERY IMPORTANT, if using a PC, download a copy of Network Time Synchronization to make sure that your time on your PC is EXACT. Install and run it everytime before you initiate WSJTx. You can go to time.is to see if your time is exact. I hope that helps. If you have other questions, hit me up on email. 73!
Nice video, thanks. I've noticed awful giant vertical lines that appear out of nowhere, on all bands (!), normally at about 1600hrs, when I'm doing FT8 in the garden with my IC-705 and MPAS 2.0... No idea what it is, found one mention of possible noise caused by faulty power lines (but why would it appear and then disappear within an hour...) Could we catch the bad Cuban vibes here in England?... 🤔 Maybe I need one of these kits... Keep up the good work. 73 de Manny-2E0HJN 🇬🇧🤝🏻🇺🇲
Your guess is as good as mine on those lines. I am researching more about that and will do a follow up when I get more knowledge. RFI can come from anywhere inside or outside the home. Finding and eradicating it is all of our goals I'm sure, but it doesn't make itself known easily, right? Thanks for the comment and for watching. 73!!
@16:00 it sounds like someone came home from work and turned something on and then off after they are done using what ever is causing the noise. I would start observing which one of your neighbors is getting home about that time.
The ferrites should be sop. I bought a dozen off Amazon for under $15.00. Also, some jerks around 7.150 like to play games. They'll tell you how bad your signal is. In reality a bunch of jerks who were probably bullied as kids, tossing terms out that they don't even understand . I've been in radio 43 years. Everyone is an engineer. Make sure you ground the equipment and add the coils. If you get really down to it, every station has some rfi. Get a 2nd opinion.
Hey!@ I appreciate the comment and info!! I guess every hobby has it's share of jerks...LOL. I also bought a set of the ferrites off Amazon and my experience is that they didn't offer up much protection or difference when used on things around the house. I ended up going to Palomar Engineering and purchased their RFI kits, which worked to a point until a neighbor put up solar panels on their roof!! So not I have purchased a kit to hopefully install on his solar setup and reduce that RFI that plagues me now. Thanks for watching! 73!!
The things I have found in this house over the past three year astonishes me. I have had to go back and repair quite a bit of errors that were made out of sheer laziness or lack of skill. Either way, as I find it, I am fixing it the RIGHT WAY! That 9 year old sucks!! LOL Thanks for the comment and for watching. 73!

@@HR4NT I just went on and see I can buy that price separate like I thought. My gut tells me as long as the filter is in line it will work. I think they suggest it go straight into radio because now there isn’t any other coax to worry about
@@HR4NT just got off the phone with Palomar and they said it will work! 73
can you buy these for the FTDX10? many thanks.
That may be possible. You can contact Palomar Engineering and see if they have a kit for that particular radio. I hope this helps! Thanks for watching and for the comment. 73!
Could you use a Icom kit on a Yeasu radio? Why are they radio specific?
The parts they give you are based on how many and what type wires you have in each radio. The toroids they give as well as the ferrite enclosures are exactly the same for both radios. The only difference I can identify is the quantity. Thanks you for the question. Hope my answer helped. Thanks for watching. 73!
Hello Scott I just received my 991a. What did you do to do digital modes, Ft8. The gray matter is shot on this end. Looking for some short cuts.

For doing FT8 with the 991 you will need the usb cable for the 991 that will go into your computer. You will want to get a copy of WSJTx and i like to use Grid Mapper in conjunction with it to see where my signal is going when doing FT8. That was really all there was to it. There are some configurations in WSJTx that you will need to do to make it work. ALSO, VERY IMPORTANT, if using a PC, download a copy of Network Time Synchronization to make sure that your time on your PC is EXACT. Install and run it everytime before you initiate WSJTx. You can go to time.is to see if your time is exact. I hope that helps. If you have other questions, hit me up on email. 73!
Nice video, thanks.
I've noticed awful giant vertical lines that appear out of nowhere, on all bands (!), normally at about 1600hrs, when I'm doing FT8 in the garden with my IC-705 and MPAS 2.0...
No idea what it is, found one mention of possible noise caused by faulty power lines (but why would it appear and then disappear within an hour...)
Could we catch the bad Cuban vibes here in England?... 🤔
Maybe I need one of these kits...
Keep up the good work.

Your guess is as good as mine on those lines. I am researching more about that and will do a follow up when I get more knowledge. RFI can come from anywhere inside or outside the home. Finding and eradicating it is all of our goals I'm sure, but it doesn't make itself known easily, right? Thanks for the comment and for watching. 73!!
@16:00 it sounds like someone came home from work and turned something on and then off after they are done using what ever is causing the noise. I would start observing which one of your neighbors is getting home about that time.
The ferrites should be sop. I bought a dozen off Amazon for under $15.00. Also, some jerks around 7.150 like to play games. They'll tell you how bad your signal is. In reality a bunch of jerks who were probably bullied as kids, tossing terms out that they don't even understand . I've been in radio 43 years. Everyone is an engineer. Make sure you ground the equipment and add the coils. If you get really down to it, every station has some rfi. Get a 2nd opinion.
Hey!@ I appreciate the comment and info!! I guess every hobby has it's share of jerks...LOL. I also bought a set of the ferrites off Amazon and my experience is that they didn't offer up much protection or difference when used on things around the house. I ended up going to Palomar Engineering and purchased their RFI kits, which worked to a point until a neighbor put up solar panels on their roof!! So not I have purchased a kit to hopefully install on his solar setup and reduce that RFI that plagues me now. Thanks for watching! 73!!
Great idea I think I will look into this issue. Really feel sorry for the people that hired that 9 year old. Ha ha ha ha
The things I have found in this house over the past three year astonishes me. I have had to go back and repair quite a bit of errors that were made out of sheer laziness or lack of skill. Either way, as I find it, I am fixing it the RIGHT WAY! That 9 year old sucks!! LOL Thanks for the comment and for watching. 73!
RFI is annoying and is becoming more common.
Tell me about it!!! I am STILL dealing with the solar panel neighbors. Thanks for watching and for the comment. 73!!
Looks worse
Time of day and position of the Sun can do that. Thanks for watching and for the comment! 73!!
