Long story short: I have a setup that works great about 95% of the time for all of my available OTA signals. I have an alternative setup that works great about 99% of the time for all of my available OTA signals except one. I've done some experimenting and believe that this one station is too strong and that is why it doesn't show up on my HR10-250's receiver which is sensitive to overly-strong signals. I've used the Radio Shack attenuator, but unfortunately it cuts down the other signal too. Does anyone make an attentuator for just a single frequency (channel 47), or are their electronic kits or schematics I could buy to make my own?
