In my short tenure as a RR member I have read many postings and do like the idea of sharing information. But I will make a simple point that when comparing material posted on various web sites and comparing it with a localized printed publication I often find that the paper book is often more accurate especially if it is published often. Also, when I travel especially to Washington State I enjoy the WA & OR book put out by Scannerstuff as it is something that I can hold in my hand and use as a quick reference and feel that it is reasonably up to date. Over the years I have collected numerous books related to monitor radio listening including several of those related to the Nevada book you make mention to.
I come to NV several times a year and find it helpful and I do with other books for AZ and WA & OR. Again, I do think it is nice that people help out one another but I don't expect people to "spoonfeed" me or anyone else in terms of giving out most everything they know about monitoring in the Las Vegas area or any where else. I would not expect people to copy out of a book and post it on some web site either for a number of reasons. Lastly, searching the radio spectrum for frequencies, talkgoups, systems, and other elements is a lot of fun. But if I feel like buying a regionalized scanner book I will if I feel it will aid me in my hobby. I enjoy looking at my bookcase filled with radio related books and the Southern Nevada Frequency Guide takes up a small portion of it. If I wish to praise it or any other book I will and use it I do.
