Does this put "hum" or interference into the electrical line, I need an adapter for m modem that doesn't make a horrible "BUZZ" in my radio!

Yes..Intermittantly. Its a terrible product. I cant even get it to connect right. Sometimes I would have to shove a book up against it so that the connection would stay in place. It is nooooo where near the quality that is the original one that came with the mic. Not worth the money...but I have not found an alternative. UGH!

Mine does not make any sound at all, how ever when I first got it and plugged it in , i checked all of the adjustable settings and they were right on. I left my two way radio plugged in for about a week on six volt, took it out one day and did not get one hour of operating time, the battery was low.When I got home I checked the voltage again, my six volt now only puts out three volts. I have to switch it all the way up to twelve volts to get seven volts. I would not buy another one of this brand. Maybe just bad luck I don't know. Dave

I would suggest moving the modem to another room to get it on a different circuit. That's the cheapest way to fix this problem confidently.

I installed this amp as a secondary amp to power the hogtunes woofer upgrade. There is no interference with the radio at all. But I run the original antenna on my ultra. If you have the hidden antenna it could have some affect..

Lucy,I found the source of my hum. I have Direct TV HD. I found that going into the menu settings/Audio/Sound Effects and turning that option off, I was able to rid myself of the annoying hum. The option has something to do with keeping the audio settings from channel to channel, while it is changing you hear dead air except for the hum. Nice and quit now. Love this receiver!Larry

It's difficult to say. While it could be component failure in the amp, it could also be interference between your location and the broadcaster, such as larger trees than before, newer buildings or even machinery in factories. Digital transmissions are delicate, and I find my reception is affected even by windy days moving the trees and branches a lot. I know how frustrating it is. Try moving the antenna location, even a foot one way or the other can make a huge difference with DTV interference. My internet-cable company installed a new modem in my house and now I can't get any AM radio reception due to the terrible noise it is silently generating on the airwaves. Just loud buzzing. As soon as I unplug it, I get perfect reception all over the house. Could you have anything new, nearby, ie Microwave oven, electronic power supply for laptops or phone chargers etc? I find that a lot of the offshore made electronics lacks proper shielding. Very poorly made stuff. Just some ideas. Good luck.

I don't know. All I can tell you is that I have a tv, computer, two stereos and dvd player plugged in. If I connect any one of the to another or turn all on at once I get no hum or static. The volume is a little reduced with each button pushed down but no other issues. It shouldn't matter but maybe a shielded cable? I used to have an old computer that produced radio frequency interference. It made static on the older tube type television if it was close to it when I connected cheap audio cable to it.. just throwing that out. Good luck.

What's humming??? The antenna or the amplifier/rotor box???? Mine doesn't hummm at all.......

Well some noise is normal and that seems to be what you have going on. If your near a computer or router or any fluorescent lights you will get some EM interference. And that is what it sounds like in your video. You can buy a cheap noise gate and set the threshold to say -75 db and that will clean all that up.

I notice zero AC hum or any whine. I would use this again. I will pass on stay clear of tranmittion over AC wiring S/R units---I think Black Box was the one I used. It has a delay and gets hot.good luck

his will not take out a bad grounding situation!! power conditioners do not do that. what your hearing is 60hz hum, meaning that the circuit in your system has started a loop, also if its audio, make sure to use only balance connections or isolation transformers! try using one outlet for your gear and make sure nothing else is sharing the same circuit

I noticed it too. When the device is connected via the instrument connection the floating ground will cancel any noise. One must remember, this isn't a professional piece of equipment with layers and layers of MOSFETS, JFETS AND TRANSISTORS To switch on and of the signal. So, even though there is no signal, it's amplifying the hum from the AC transformer as well. In common terms, it needs to be connected to a device to cancel the noise. Even in the ground, or lift phase.

i've never noticed a hum. The red LED is a bit distracting, but I just turn it away from my line of sight. Seems to work just fine overall.Note: I am not an audiophile and don't hear frequencies much above 10 kHz. Sometimes other people hear things that I don't. FYI.

Have you noticed if yours hum? I'm wondering if sinking the box into the wall- as you did, will help decrease the buzzing sound they emit. Thanks for any insight.

Remember, this is to stop grounding faults so when you plug something like your computer sound card into your TV, you don't get that hum. You probably don't need it on most of your tv's.

Thank you! I finally solved the hum problem by plugging the iMic into "Line Out" on my amplifier instead of directly into my turntable. The hum disappeared! Hope you got your hum solved, too. Maria

Mine also hums but just when setting there, as soon as I turn on the radio on the humming quits. It did hum one time and all I had to do was turn off then back on.

Not well. Then again, it doesn't work with anything very well. If you don't want some serious line noise, I would strongly advise adding about $40 for a much better unit.

Yes, this will help if you have a low signal level getting to your modem. If you don't have too low a signal level then it will do nothing useful. In other words if your signal is lower than about (negative) -13dBmV this may help. If it's higher it won't.
