AM noise Antenna makeover

Due to extreme radio interference, extraordinary measures were taken to reduce RF interference to one radio station over 100 miles away. I acheived this feat by mounting my Terk AM Advantage tuneable loop antenna to a vise that was attached to a simple flimsy cheapo camera tripod. I precisely pointed the loop to reduce the received radio interference and connected my Table Top Radio (Radioshack Accurian) to 75 feet of 75 ohm coax. had to fm modulate the audio output from this radio in order to hear what I was doing on my terrace but as you'll hear, the time and trouble was definately worth while.

I hope you disabled Hybrid Digital on your HDRadio.

@jjovereats No real need to these days for the battle of night time digital reception, has been lost to but the very few AM stations out there that still do it and do it well enough for superb local recovery 24 hours a day. I'm glad my WTAM 1100 Cleveland still does, for it affords me tastier audio of Coast 2 Coast when I wish to here them clearly sans internet connectivity. Most have piggybacked onto their sister FM's with so-so yet fade free 24/7 reach.

Good example of what your radio will sound like when and if we allow the Bush-ized FCC to continue with BPL. This is also the result of the FCC NOT enforcing RF noise floor regulations, caused by every number of modern appliances and machinery which is SUPPOSED to have RF noise suppression, as well as the power co. itself.

I agree! I'm an HD radio fan. There are mixed opinions on the wideband digital "hash" HD artifacts. That being said, BPL is the bigger interference threat to AM as power lines form enormous wire antenna radiators and I fear that the best made efforts at band-stopping AM broadcast band spectral interference through aggressive filtering, WON"T BE GOOD ENOUGH TO SAVE AM from its OBLITERATION.

Thanks for the demonstration of a good antenna tip. 73
