I began having this issue some weeks back. I figured it was probably user error, but after talking to some fellow scanning hobbyists in the area, they've been having trouble too. Basically, my Uniden BCD536HP stopped getting Marcs. There have been 2 or 3 days where it comes back, but never lasts longer than a day. Here is the stranger part-I work in Mercer County and take the scanner with me each day. Once I get back in Mercer County, I get everything back. Celina PD, Mercer County Sheriff, OSP posts, Allen County Sheriff, etc. Leave and go home? And its analog only. I've done all I can think of, from reset to going full database and also changing zip codes and range, and also putting on the ATT. Not much improvement. Short of moving from St Marys to Celina, I'm at a loss for what to do (if anything can be done) to solve this. So, I was wondering, has anyone heard anything about tower troubles, reduced power, getting ready to change frequences that might suggest this is short term? I really don't think anything is wrong with my radio.
