I was just able to barely receive the Beekman control channel with a 536HP. The scanner is showing that site as NetID 12, SiteID 5, CC 5. DSD+ shows it as NetID 13, SiteID 6, CC 5.
@pro92b I was posting this while your post popped up, so we have essentially the same results for two sites using the same model scanner.
The thing that makes me question the accuracy of DSD+ is the Color Code. Generally speaking, you'll find that most DMR systems match the CC up to the SiteID. Obviously there are exceptions such as the OneVoice system, but it holds true often enough for me to have some doubt.
