Today my 2.5 year old SDS 100 stopped receiving anything. First noticed it in a trunked p25 system. Went over to weather and all I hear is faint static on every frequency I scroll to. I do notice that in both the p25 and the weather my RSSI is at -40 almost constantly. All I’ve tried so far is turn off, remove the battery and took out and placed back in the sd card. No improvement. Any thoughts? Is it toast?
