I'm 55 years old , lived in western Suffolk County all my life and have owned scanners since I was about 12. I have never know of a club , that would have meetings etc. I have spoken to a few hams I know that are in clubs and a couple of them said there is sometimes a little scanner talk in their ham meetings. Years ago there was a great scanner program that was done every week , I think it was on Tuesdays , that you could listen to on 146.something. It was run by a gentleman in Merrick and was very informative. If you had a ham you were able to participate on the air , if not a ham you were able to write in. They had a monthly newsletter that you were able to get if you sent in an SASE. I'm sure it's been at least 10 to 15 years since the last program. I do miss it. But besides that , I do not know of anything solely for scanner enthusiasts on Long Island. Hopefully there will be a post here to prove me wrong and if there is I would gladly join. The forums here are full of very helpful people , there is also the uniden web site forums , not as active as here but between the two I'm sure they can help you out.
