I received my new BCD-536 today. I have a friend visiting the area, and he just happened to receive a new SDS-100. I am surprised in the performance difference between the two, as the SDS-100 seems to have a much better receiver. We were doing a bit of side by side comparison. I was using the stock telescopic antenna and he had a Remtronix REM-820S antenna on the SDS-100. The SDS-100 could receive signals the BCD-536 could not.
I live on the coast just a few miles from the NC/SC border. When trying to monitor the Horry County, SC Fire and Rescue. He was pulling in transmissions I could not even hear, with twice the signal strength. I can see the signal strength on the 536. reading about two bars, but hear nothing in the way of audio on that particular system.
The SDS-100 was receiving the same signal at four bars, and the transmission was loud and clear. Unsure if I have a defective unit or there is something I need to change in the menu.
