I have had my SDS100 since last Friday. I really like the unit itself but I am having reception issues and looking for some help. I first tried my unit in upper lower Michigan in Iosco/Ogemaw county area. I can hardly pick up anything on the new scanner but my BCD436HP picks up the transmissions with no problems. I was listening to the MPSCS. I have tried everything that I can think of, I even locked onto two several known good sites (Ogemaw police dispatch for example) and BCD436HP was crystal clear but nothing on my SDS100 even with the squelch set at zero. I have tried using zip code and GPS coordinates as well. I have all my sites on as well. I have had the scanner on for hours and once in awhile I will get a hit but its very faint and distorted. I have tried changing delay time and attenuator off or on just to try. I also have a home in lower Michigan and I am having the same problem, can not pick up anything and this is a large metro area. I see sites coming in at 5 bars and lock on them but can not hear anything and also when I do get a hit its also very faint and distorted. Even the weather is very distorted and loosing transmission but crystal clear on my BCD436HP. I did see a post where there was a bad antenna connection that the user soldered and it really helped, not sure if thats whats going on with my unit. I even swapped antennas from one unit to the other and made no difference. I am just not sure what to do at this point and hoping someone can give me some direction.
