Got mine today, I can confirm the following: CPU Noise in the Speaker, worse with extension speaker. Sentinel does not compare at all with Ezscan, going to be much harder to program than Whistlers I have. Looks like I need to buy Proscan to do the things I want like monitor error rates in real time?
Simulcast was better than all other scanners I have or had with included antenna. We will see what happens on an external antenna.
LAN port is DEAD. It does not light up with several known live ethernet cables plugged into it. Likely have to send back to Universal Radio after I call them on Monday.
