Greetings -

I'm looking for advice on the proper noise filter/suppressor to attach to my Funkwerk ATR 500 radio. It's a long story and I'll spare all of the details.

About seven months ago, the radio wouldn't work, so a experimental aircraft friend looked at the radio and figured that the noise filter was toast, so he extracted the filter. The radio worked (then and now), but there's an annoying transmitter sidetone/feedback. At the time, one of us just discarded the filter, so I don't know what it was/is.

I'm searching the internet for an answer, but nothing is popping up. Does anyone here (hear - ha ha!) have any idea what the filter might have been? I have feelers out elsewhere, too, including Funkwerk.

Thank you,

Tim
 
Aircraft spruce has a good one. Lonestar Eliminator.

 
Dave - I thought that I had written a thank you a long time ago, but it didn't make it. So, here's my belated thank you very much for your response!

Did you end up buying and installing it? There are other things you can do to eliminate noise at the source, but this filter works good.
