Nick, not sure what you might be eluding to here, you're being too cryptic. Just spent about an hour listening with IWN on pro 197 and my 996 base, with WSP on the pro 197 as well as the IWN, but when WSP locked on, 996 just kept on scanning. Please note that I have taken the local sites (basically Mt. Defiance to Naselle/ Baw Faw thru Metro Portland's sites) and put them as a separate quick key and duplicated them so they would repeat these sites in order to focus on this WSP mess. Thus far there seems no crossover. Please note as others here have reported, Dist 5 seems to be doing quite well VHF P25 without being a TRS (a stupid move IMHO).
While I'll bet that it works great on 700 up around the sound, it's stupid here. That being said, given their new radios, I don't know why they haven't gotten an actual TG on CRESA's TRS instead of merely a monitor (receive only) TG. On WSP's side, they require then a VHF"broadcast" of CRESA on 155.07 (licensed at a couple of sites, but who knows if it's anything but their station tower) which while I'm told is switchable to dif TGs, almost universally is set to CCSO disp (Control 2). Have no idea if it's a technical issue or merely territoriality by CRESA, but it would seem a better way to have actual interop more than LERN which locally is a joke and one of the worst TGs in terms of audio quality.
Perhaps the situation up North is different, or you have intel or you are aware the IWN is capable of certain things, however thus far "boots on the ground" can report that the systems while perhaps connected and sites used, appear separate. I'm no expert obvioiusly, nor do I understand what's going on (or supposed to be), but the one question I keep asking is the one I posted above about linking repeaters or simulcasting perhaps. (BTW, just had low band 45.36 key up testing. Tech said was F-1 on Capital Pk. That's quite a stretch for Vancouver, and it was not only rock solid, but LOUD. Must retransmit over the loop to site here?)
Anyway, I digress. The fact is, if you have something to impart, which you normally do so well, would you please come out and say/ask, because something must be different here than there.
