For all of those that have submitted data:

Please review your submissions and update the frequencies. Most of the data collected has changed since it was submitted. From my examinations, almost every site has at least 3 frequencies and the core sites (hubs) have 4 frequencies.

I think users are missing a lot of transmissions due to this fact.

I agree whenever possible however, that can be difficult on some rural sites with little traffic. That’s the status of many of the sites I’ve recently submitted.

Well I was actually referring to using the FCC database. A lot of the East region sites don't have FCC licenses listed. Most of the sites have been updated since they were first reported.

Don’t most scanners nowadays work off control channel only, figuring out the voice channels automatically?

Yes but where did voice channels come into this thread? I am talking about the control and alternates. The Harris system changes active control channels *frequently* (on certain sites) and thus users need to make sure they have all of the correct frequencies.

I'm presuming this one is 041 Site ID? The Roosevelt was 040?

Thanks for that posting @kd7jfv , I'm in west Pasco and my scanner doesn't hear anything at those freqs.. Also interesting is the neighbor map, there are several nodes listed that aren't in the DB here (sites like 131, 117, 100). Guess we still have lots to discover

Well since the site is ~45 miles to the NW of you then you'd probably need an external antenna.

If there are any SDR or Pro96com users out in the SE part of the state (Pullman, Asotin, etc.) then please help fill in the missing pieces. Also we could use some help in the north central areas too. A lot of the early data has changed and/or is misleading so if we can get recent info then that would be great.
