Hi again John. Here's a chart of the PRO96 sensitivity specs:
http://www.starrsoft.com/software/win96/FreqTest.asp Except for a small bump at 300MHz the're not to bad. You should be able to hear something if they are close enough. Don't know what type of antenna you are using, rubber ducks are not usually the best for MilAir. I have a Radio Shack 20-006 (about $16 I think) that works pretty good for a handheld antenna. Just about anything up in the air on the end of a cable is better though.
I also haven't had much luck programming "common" MilAir freqs in my scanner. I've done a lot of Google searches, etc. and have not found any gold mines out there yet. I finally broke down and just spent time searching from 225-400 MHz. I am lucky that I live about 5 miles from an Air Force base though, so my searching has paid off. None of the freqs I've found this way have been on any "common" list I've seen.
I started using a PRO95 (a waste of time as it turns out - deaf as a brick in the MilAir band) but I didn't know it at the time and was the only scanner I owned. Anyway here is how I made it search MilAir.
1. Pick an empty bank and program 225.025 MHZ, mode: AM, step: 25 into the first location using Win95.
2. Disconnect from the computer.
3. Select the bank I just programmed.
4. Press SCAN
5. Press MANUAL
6. Press FUNC
7. Press TUNE
8. Then press the up arrow key.
Off it went! It would then scan up to 400 MHz where it stopped when it hit the next factory programmed band. I could then start again by going to step 4 above and pressing the keys again.
I don't have a PRO96 (no digital in my area yet), but you may be able to work something similar out on your PRO96.
Since you mentioned the Coast Guard, and your close proximity to the lake up there you might want to program marine channel 16 into any MilAir band you might set up. I'm sure they have rescue helicopters and if it was a serious enough emergency they might respond. This would alert you to at least start searching for some activity.
BTW I use an AOR8600MkII and a PRO97 for MilAir now. The PRO97 is only a month old but has pretty well replaced the AOR. Scan speed is 100 ch/sec for the PRO vs. 30 ch/sec for the AOR. AOR also has always had a very touchy squelch control, seeming to need a lot of re-adjustment all the time. PRO just set about 9-10 o'clock and works fine. AOR is difficult to learn to use as it has about a bazillion settings, and text tags using the thumbwheel is a real exercise in frustration (when it gets lost in the japanese character set in there you'll really go nuts!). The PRO is much easier to understand, use, and program (but of course won't do nearly as much).
Ya pays yer money and ya makes yr choices.
Luck
