Marion Co scanner group
Hi Jim,
I live in Seminole County, occasionally make it to Marion Co. I'm not aware of such a group, but there are some very active scanner hobbyists there. One of the most active on Radio Reference is Kevin Hoelldobler. If you look through the Florida forum here, you will see many posts from Kevin.
If there are enough scanner hobbyists in the area who are interested, you and they could arrange a monthly, bi-monthly, or quarterly meeting to share information, demonstrate various radios and software, etc.
There have been a couple of such scanner groups in the Orlando area. The longest-running is the Central Florida Listeners' Group. On Sunday night at 8pm, the CFLG has a ham radio net/discussion group on scanning and other aspects of the radio hobby. The net is on 147.12, I believe. I now work Sunday nights and can't monitor the net. If you can catch this signal, you should enjoy the net.
Also, the CFLG has an email list on Yahoogroups that you can join. Members post questions and information.
Hope this info is helpful
