Before I Send it to the dreaded repair... SDS100 had been working fine, started acting strange. shows full bars signal on multiple (4) P25 P1 and P2 systems but now does not show DATA and does not see any traffic, seems to cycle through control channels. I know the CC are correct and 1) this has worked for years, and 2) another scanner uses the same control channels and works fine. Tried hard reset, reloading the programs. I have found that sometimes if I cycle it off and on multiple times sometimes it comes up with the DATA and voice. then it works perfect until I power cycle it again. Anyone seen this? thanks
