Radio interference

IllinoisRRT · Post by **IllinoisRRT** » Mon Jul 18, 2005 8:52 pm

I set a patient up last week with a CPAP and he called me this morning to inform me that he had not used it yet because it created static and feedback on his radio. He has a Remstar, and in talking to Respironics I found that this will happen, due to their universal power source, unless he moves the radio farther away from the CPAP. Has anyone else had this problem and solved it? I'm not going to make him very happy in the morning when I tell him he has to move his radio!

I have a REMstar Auto and I had a radio sitting directly next to it for quite a while and didn't notice any interference at all. It's a very new radio, so maybe it has better rejection to RFI.

You may be able to purchase a 12 v power supply at radio shack or run it directly from a 12 v battery. You could sell it as a backup power supply. ...... Or just move the radio ..... Wrap the cpap in aluminum foil and ground it .

On second thought. He must be listening to an AM station. Tune it to FM and leave ....FAST, before he notices.

I have one of those alarm clocks that synchronise with the Atomic clock radio signal and I kept it on top of my Remstar auto so all my buttons would be in the same place in the morning. It would NOT pick up the radio signal when sitting directly on top of the Remstar, but its a pretty marginal device in the first place. (Do NOT buy Oregon Scientific clocks! ...in my opinion) When I moved it a SHORT distance away, it worked as good as it does anywhere.

Yes, radio reception is a problem. If I wake up to a big thunder storm rolling through I can't get the decent AM station for weather. FM would go on and the western suburbs could blow away before they would have it broadcast.

I have to use the darn buzzer on my alarm clock radio on work days.

I came across a zen alarm clock on the internet tonight. Too bad it was really pricey. I might be a less anxious morning person if I had one of these pleasand alarm clocks.

IIRC the best storey I have heard on 'radio interference' was when some famous hollywood star would drive past a particular radio staion & receive the signal through her fillings. Loud enough & clear enough that she could name the song & recite the talking.

MY Remstar Plus wreaks havoc with my "distant" AM stations, some nights it's worse then others.....

Oh yes, AM stations at night are very interesting. They bounce off the ionosphere. Thats why you hear alot of spanish at night. Stations from Mexico take over the airwaves. Fortunately I don't need an alarm. I just wake up at 6am every day. Including weekends We use the ADF (direction finder) on the airplane , which is an am radio to point to the thunderstorms. Gotta look out for those mexican radio stations also. Unless you want to go to Mexico..

Just get him set up with a 10' hose and move the machine away from the nightstand with the radio on it. This may help.

That was Lucille Ball. Interestingly enough, MythBusters did a story about it a while back and debunked the whole thing. Luuucy, you got some 'splainin' to do!
