I have a Radio Shack weather radio that is tuned to NOAA Gore Mt (162.450 MHz). I can pick up the transmitter fine. My problem is the radio constantly says "check op" because it has not received any alerts or tests. Does anyone know if NOAA is actually sending out tests from the Gore Mt site? I know the last round of snowstorms we were under winter storm warnings, and the radio never went off for any warnings. Just kinda curious...
