But lots of AM stations now broadcast over the internet so if your wife has a computer or laptop or smartphone or other source for online broadcast, that would be the best option.
When I plugged in the ClimateLine and let it rip, and then the wife turned on the radio, there was another high pitched tone. From the radio. Not as high as the ringing in my ears but almost as loud. The difference is that this sound everyone can hear.
She has become accustomed to her night time radio show and I've accepted that. She wants to continue with her listening but if the ClimateLine is causing radio interference (and it apparently is) then what can we do to remedy this problem?
