We currently own an HP 1 & 2 & are running the latest Sentinel software ver. 2.03 rev.3. We noticed that for some reason after the computer was off for a day that reopening the program we lost several of our stored Favorite lists. They were saved prior to this event. Is their a glitch switching from HP1 to HP2 radios within the same software? Also unrelated to this problem but annoying is to hook-up the HP2 to the the computer you only have one USB jack so if you are using this & to power unit, it must be unplugged switch to batteries to accomplish this task at least with the HP1 it had a separate jack for AC.
