looking for.<br>
Around 4years ago the AM reception in this section of our condo complex became <br>
rather noisy, however, walking around 90degrees on the balcony, the noise is <br>
gone, but its not like I can hang a wire out there. HOA would have a fit. So I <br>
remember there were rf chokes you could put between the antenna <br>
terminals-and-the radio--and-it would filter out noise. In checking with HRO, <br>
they didn't have anything other than for short-wave. Because of this noise, its <br>
hard to receive AM HD signals consistantly. Other than an informative <br>
discussion, if folks didn't want to clutter up the list, you can write directly. <br>
Thanks so much in advance. Board members here will not trouble shoot the noise, <br>
even if its servalance equipment in an ellavator.<br>
I suppose a spectrim analizer would find the noise, but I certainly don't own <br>
one.<br>
Thanks so much in advance for any guidance<br>
