With the homepatrol the best way to use it is by using favorites lists instead of the DB. You'll need the Arc Patrol software and the homepatrol extreme update but once you have those you can turn it (the home partrol) back into a regular style scanner again, in some regards.
Frankly, a lot of the NL DB is incorrect anyway with a lot of the conventional freqs modulation incorrect (fm when it should be am for example).
Using the favorites lists makes it much easier to control what you listen to and gives the ability to quickly flick a group on. For example, I like having the Fire Departments scanning full time but really do not need to here EMS ever (it's just sad and a little too nosy). But, in the DB EMS and Fire are grouped as one. Now, I can use the DB on the HP and "avoid" the EMS but then if I need to turn on EMS for some reason I have to wade through the avoids on the HP and unavoid them. This is tedious. So, I created two favorites lists one of Fire and one from EMS. EMS stays off most of the time but fire remains on always. Plus then I could correct the erroneous modulation entries in the db and change the names of things. FYI, you cannot edit DB entries unless you add them as favorites. So, for example in the DB for RCMP on the edacs analog site, talkgroup 529 04-021 A RCMPBELLIS Bell Island Is NOT actually "bell island" but is in fact the talk group used for Ferryland, Bay Bulls (southern shore), etc. and Bell Island. Really, it's Avalon East. The update was submitted to the DB but it'll take a long time to update. So I just changed it in the RCMP fav list on my home patrol, the same as you would a normal scanner.
Further, you can then edit your entries in the favorites lists further to adjust the "range" so that those frequencies will never be shut off (or input the info for missing DB entries).

Back on topic of Newfoundland.
Jay just noticed 662 05-026 A RCMP Pr Chat RCMP Provincewide Chat (patched to P25 TG 662) Interop
This is actually just a travel channel. The only comms on that talkgroup ever are police checking during travel on the highway. They don't use it for "chat" just status checks for officers doing long travel across the highway. :-/
