i have a used midland WR400 weather radio and it keeps saying check reception on the front display. i went to listen to the NOAA weather transmitter and i heard nothing but a 12Khz sine tone during a snow storm in February then after the storm was over i could hear nothing, not even static over it. the AM FM function still works though it won’t save the station presets. what is going on? i need help. the NOAA transmitter is still working fine because i have a Runningsnail weather radio and it works perfectly.
The tuner on it might be bad. It’s a known issue with several Midland weather radios, particularly V5 WR100s and later WR300s. Might be case with your WR400 too, especially if another radio can receive your local NOAA Weather Radio station fine.
Some people have tried fixing them, but this voids warranty. If you have a warranty on your WR400, I’d just go through Midland to get a replacement unit.
