Evening all.
This is a audio related question, but has to do with a certain radio station and a wireless cell phone. I live North of Chicago Il. and listen to a ceertain powerful all news station on AM (WBBM 780). We have a phone answering system with 3 wireless headsets. If If I am listening to the Chicago station and the phone starts ringing, usually for the wife, a loud whisteling noise happens and stays there till the call is finished. This only happens on this one station . I have tried unplugging radio, the phone system, but no change. If I change the radio station to another, all is well. I have tried moving the direction of radio, it is a digital one, with nothing any different. I am really sorry to ask this group about my issue, but it is audio related. If not for this group, can someone , maybe, give me direction on where to turn?? Thanks, Morey Worthington

Hello,
I am guessing it is a Radio Frequency issue. Your wireless headsets transmit at a frequency that either matches or is a harmonic of that frequency of your radio station and the radio is dutifully playing what is transmitted on that frequency.. As they are wireless devices you cannot add chokes or filters to them. You could try ferrite chokes on the radio but I suspect that it is the radio's antenna picking up the headset signal. So you could try a number of things to separate the 2 devices. Use an external antenna for the radio. Put a large amount of metal between the radio and headset creating a Faraday cage so that the headset signal cannot reach the radio's antenna. See if the headsets have an alternative frequency that they use. Or encourage your wife to use a wired set of headphones. At least to test the hypothesis. If so, and that station is on 780MHZ then you 'll have to look for a different set of wireless headsets that don't use the same frequency that the existing ones do.

Since the radio station is 780 KHZ, it is likely that the interference is not caused by the frequency used by the phone, but that it is getting interference from the digital circuits in the phone. Usually this happens if your radio is close to the answering system or that you have placed the wireless headphones near your radio. If neither is the case, check to see if the cords running to the answer machine might be passing close to your radio. Gina is right that an external antenna probably would correct this, but moving the answering machine or making sure your headphones are not near the radio should help. If you keep your headphones in a charger when they are not being used, check to be sure the cord to the charger does not run close to the radio. Making sure the radio is plugged into a different outlet from the answering machine or any headphone chargers might be worth trying as well. If your radio has a separate square loop antenna, moving that around can make a big difference as well.
I live in Minnesota but listen to WBBM occasionally, and I have heard them announce that they are also on FM on 105.9. You might be able to avoid this by trying the FM frequency instead. I do not know if the coverage of the FM frequency reaches you, though, but it might be worth checking.

Hello Steve,
URRRRR, shows you how long since I listened and took note of the AM band. Whoops. At least someone is there to put me right. Found it interesting that other radio stations perhaps not on AM did not suffer in the same way.

If I take my cordless phone and put it near an AM radio, I find that it generates a good bit of digital noise across the entire AM band, but there are oscillations that occur here and there that are stronger than the general noise. I would guess that on his system, one of those stronger oscillations happens to hit WBBM. Unfortunately, it is all a bunch of guesswork on my part and there is a lot we don't know about his system. I might be totally wrong. I am struggling with a problem with noise and interference on the AM band in my house which is very hard to track down, so there might be something more to this problem as well.

Agreed completely. I had a sudden increase perhaps a month ago in the interference I am getting on the AM band from my DSL service. The phone company must have changed something either with the phone lines outside or with the DSL settings. While I know there is always DSl interference along the wires carrying the DSL signal, it is also getting radiated from the AC lines as well. I can't figure out how it is getting into those circuits. I have a tuner with one of those little square loops and I made a larger loop on a piece of cardboard and added a length of cable so I could move it around more. That really helped me escape some interference until this new DSL problem started. I still like to look for long distance AM reception especially during the winter evenings, and this interference really decreases my ability to do that. Best regards, Steve Jacobson

Hello,
It wouldn't hurt getting a couple of those ferrite chokes and putting them on the lines. If on a power line put it on the cord as close as possible to the power source. You may have noticed that the more expensive USB cables, audio lease and power supplies will have a ferrite choke on them. I had a buzz with my AllStar MicroHub. I had a ferrite choke that I think was on a Decktalk Express serial cable. So I opened it out and wrapped the cable about 2 turns and closed it back together. Because the thin wire wasn't gripped I didn't think it would work. But it did very well. Very useful to have some kickingarond. Be careful though, I just brought some and they are not hinged.

It is back interference from the modern switching power supplies. We used to use Transformers to render different voltages for the radio/television etc., but since the early 90s, we use fancy transistors to chop up the line voltage into little time segments to get lower voltage. The noise we get is from those transistors which generate incredible peaks, valleys, and harmonics. Some of the signal comes back down the plug and wire and some of it is radiated. So it's always a challenge to damp it out. There a good thing, however, or wall warts and laptop power cables would have to be a lot bigger and heavier.

There are things called line chokes which are comprised of a ferrous metal hoop through which you can wind a line cord and it will help to dampen down interference coming back up the power cable. They're not very expensive. Geoff

Those are good suggestions and I am going to do just that. I am a little suspicious of my DSL modem because there are no chokes on the cord to the AC adapter. It is strange. If I put an AM radio near the heavy ground wire that is connected from the circuit breaker box to the water pipe where it enters the house, I get almost as much noise on AM as I do when I put the radio near the line carrying the DSL signal. That ground wire is nowhere near a phone wire. I have unplugged my DSL modem stopping the internet connection and checked the heavy ground wire and there is very little additional noise then. I thought maybe what I was hearing was other noise on the ground wire, but it is definitely the DSL signal. I have been happy with DSL other than that.

I am already all filtered up in terms of DSL. For one thing, to try to avoid this very problem, my DSL line is separated from my phone lines at the box outside the house, and the DSL line runs to my modem. However, to play it safe, I did put filters on the phone line to be extra careful. I suspect something strange is happening that I will find eventually, possibly a choke on the right device. Thanks.

Hello,
I advised complaining not just because it is likely to be cheaper for you as the end user. But depending upon your contract. Such equipment is the property of those who provide you with the service. They are providing you with a substandard service and they are in breach of their contract with you. By all means fit chokes yourself if it fixes it then fine. But remember if they call for some reason ensure you remove them otherwise you might be accused of causing the fault or damage to their property. They are probably not bothered but just be mindful of such potential events. It is certainly worth taking issue with them. Arguing that when you disconnect the problem goes away. They cannot argue with that. Good luck. On 2 Aug 2020, at 01:48, Steve Jacobson <steve.jacobson@outlook.com> wrote:Georgina Call: M0EBP DMR ID: 2346259 Allstar: 52178 Locater: IO83PS

Just to be clear, I don't intend on moving their wires. The routing of my DSL line was something they do if requested rather than making it available to all phone jacks. They also put in a higher quality cable to carry the DSL/phone signal and they did that to partly address my problem. I did complain once and had them out again and showed them the problem. Even though I showed interference on a local AM station, they saw some of my equipment and assumed I was being more fussy about AM reception than was reasonable. Your caution regarding moving their wires is a good one and I am careful of that. It probably is a choke problem or something that is not in their system directly. Best regards, Steve Jacobson

Nashville, Tennessee) on that stereo; but no more as my modem pretty much wipes that out as the interference is strong toward that end of the AM band! I examined that loop thing and found that I cannot even find where the other end of that "chain" thing that it is connected to ends as it goes underneath of the next shelf of my entertainment system! As I stated in my earlier message, I can turn that little square loop thing, but as soon as I let go of it, it'll just flip back to where it was! Besides, I can listen to most of those far-away stations easily enough on either my Amazon devices or on the computer these days! Tom Kaufman!

I was never able to pick up far away AM stations in the city .. maybe
toggle quoted messageShow quoted text
sometimes late at night. It works much better out there a ways, such as where my mum lives. Picking up stations from Chicago at 3 AM in the early 90s, even with all the faintness and hissing noise, was pretty cool. Now though? I admit I just can use the internet to pick up stations from *anywhere* and I haven't actually turned on a radio in a long time. AM transmissions seem to have a potentially long range, but are easily wrecked by the kind of noise caused by everything around the urban landscape. I can only imagine how much worse it is now with all the domestic devices in one's home that emit radio signals.

I had a sudden increase perhaps a month ago in the interference I am getting on the AM band from my DSL service. The phone company must have changed something either with the phone lines outside or with the DSL settings. While I know there is always DSl interference along the wires carrying the DSL signal, it is also getting radiated from the AC lines as well. I can't figure out how it is getting into those circuits. I have a tuner with one of those little square loops and I made a larger loop on a piece of cardboard and added a length of cable so I could move it around more. That really helped me escape some interference until this new DSL problem started. I still like to look for long distance AM reception especially during the winter evenings, and this interference really decreases my ability to do that.

equipment, it's especially bad, for there's just no "getting away from the noise and interference that...even the television set emits! Tom Kaufman
