what can help too is to GROUND the radio, that decreases QRM alot and increases reception. snap-on ferrites are very helpfull. sometimes its the telephone landline where the QRM comes from into the house, snap on ferrites on the telephone landline can help to decrease the QRM alot. the powersupplies that come with smartphones and tablet computers usualy make alot of QRM too, it can help to put snap on ferrites on their powercords.
I installed a cb radio for my Autistic son and the noise and hiss was terrible so i put a few clamp on ferrite beads and helped very little! I put my oscilloscope on the power supply and the dc ripple??? Lol. Subbed and liked cheers from Australia ❤
I had problems with noise. Theres normally alot of chatter on ch19 where I live. But I couldn't make out what was being said through the noise. Out of curiosity I flipped the main breaker in my consumer unit and I could finally hear what was being said. Through a process of elimination i found out that it was my TP-Link Powerline adapters producing the noise.
Great detective work. I'm lucky to have a very little interference out here in my office. I do get occasional noise from one of my antennas. I think it's from a refrigeration compressor from next door. 73s from Northern Nevada.
@@RidgeHikerAdventures yes it was, I forgot I had the filter inline with everything. I heard something pop, thought I blew up my amp, then realized what happened lol.
When installing on power cord for providing power from a battery or 12 volt power supply do not install them on the ground side of the cord just on the Positive Side.
I put those on my Turner Plus Three but I really don't know if they make any difference or not, they do look kinda neat on a 45 year old microphone though. Cheers!!
A great video and explained just right we live in the UK have all sorts of stray RF been picked and into the radio street lights TV kids computers and stuff in the home heating boiler it's in ending. So after this video I will be buy these noise killers it's that bad little garden lights the changed the street lights to get more light at less power le lighting and it never stops but this could be a good start
Luckily most of the RF noise is being generated by my nearby devices. Like you, the worst offender is my little hydroponic garden which we use in the winter to grow vegetables. The LED lights put out quite a bit of RF noise. With it being summer, I haven't gotten around to filtering the RF noise generated from it yet. In the past, I just unplugged the lights when using the CB radio. I'm going to have to order some more ferrites from Amazon before winter arrives.
I have an automotive AM/FM radio installed at my cabin. When I turn on my PSW inverter which runs off the same 12 VDC line, I get lots of noise in my AM radio. The same thing happens when my 12 VDC refrigerator starts up. I am going install some of these ferrite beads and a low pass noise filter to try to reduce the noise. I liked your Solarcon A-99 CB Base Antenna video. I would be interested on how well it performs on the 10 meter and 20 meter ham bands. I am currently using a 102 inch steel whip antenna with some tin roofing for a ground plane for my CB. I wonder if this would work on 10 and 20 meters using a Xiegu G90. (I'm commenting here because comments are turned off on you latest video.) - Dave
Sounds like a good plan for your AM/FM radio with the noise problem. I bet the low pass noise filter will do the trick. I'm anxious to try out 10 meters on my A-99, but I recently sold my 10-meter radio with the idea of getting one with sideband. How do you like your Xiegu G90? I would imagine your 102-inch steel whip antenna would work well on 10 meters with an antenna tuner, but I'm not sure about 20 meters. I don't have a lot of experience on the bands above 10 meters. My comments should be back on all my videos. I panicked when I realized I had accidently turned them off about a week ago. Luckly, I didn't lose my past comments. Thanks for watching and 73s from 595 Lake Tahoe Nevada!
@@RidgeHikerAdventures Thanks. I have not bought the Xiegu G90 transciever yet. I am still saving up my money! I will post a review when I finally buy it. - Dave
I was able to notice a difference because I have a very low noise background where I live, I probably would not notice much of a difference with a higher noise floor. Thanks for watching!
I haven’t tried them on coax. I’ve read where others have had good luck with them. I would make sure after installing to check your SWR. I don’t know if it would have any effect, but better safe than sorry. 73s from 595 Northern Nevada.
@@RidgeHikerAdventures Placing Torroids/Ferrites on the coax (same as a low pass filter but more effective than said LP filter) will have no effect concerning SWR. What they will do is prevent common mode currents on the coax shield from causing interference to electronics in your house. You should also experiment with different mixes, I.e. mix 31, mix 43 etc. I suggest a visit to the Palomar Engineers website for more information on the proper use of the different types of ferrites and Torroids. P.S. what you are calling RF noise, if man made (cheap switching supplies, wallwarts, computer monitors, etc) is called QRM and noise from natural sources (lightning, the sun, etc) is called QRN. The power supply you referred to as a regulated supply is actually called a linear supply. Both the linear power supply and the switching power supply are regulated. Regulated means that the dc output is smoothed to provide a 13.8VDC current that has little to no ripple on the signal. Most newer switching supplies used in radio communication a heavily filtered to remove the RF in the DC output that can cause interference in the receiver section of the radio.
@@jfrphoto01 i have a cb in my car when i drive under power lines or in a built up area i have a load of static to the point i have to readjust the squelch, when i do that i end up loosing alot of range. would they make a difference in my situation
@@steffansims8729 No, that’s coming in through your antenna. If the noise comes in and then goes away after you drive by the “culprit” there is not much you can do. You can try a toriod choke. It’s the nature of mobile radio. If your radio has auto squelch you can use that while driving through town.
Hi Randall, great idea. I posted the link on the video description. Here's the link for you: www.amazon.com/Jabinco-20pcs-Ferrite-Suppressor-Diameter/dp/B07ZQZQ5BQ Thanks for the suggestion, 73s from 595 Northern Nevada!
I could not find the mix type anywhere when I ordered them. They were cheap enough to take a gamble and they seem to work well enough on my 10 and 11 meter radios. I've doubled them up on a couple of cords and that helped reduce noise even more. No noise from any of my power supplies or computer. I do get quite a bit of noise from my 2 meter radio when it is charging. I'll have to try a ferrite on the power cord and see what happens. 73s from 595 Northern Nevada.
I've read that placing them on your coax can help reduce noise. Do you have a lot of electrical interference in your area? I've read that even street lighting can cause RF interference. 73s from 595 Northern Nevada.
a lot of city lite plus I dont want to interfere with the police dept radio system 100 yards away from my house I think they would be pissed off if I turn my station all the way up say past 10 kw and wipe them off from broadcasting @@RidgeHikerAdventures
@@RidgeHikerAdventures That is so great . We have where the noise level goes as low as 3.0 but thats like 3 hours of a 24 hour day. And you sir may be the guy that can direct me on another probem I have. Barefoot radio key up and it shuts my truck off. Truck all factory, radio all factory. Ford says its an RF interference. By the way, great video.
@@Tom-xp7dl That's very strange. I found this on a forum that might point you in the right direction. www.ford-trucks.com/forums/1227929-radio-frequency-interference-rfi.html 73's!
