Some of the following are dedicated traffic nets. Others are mostly ragchew nets.
There are hundreds and hundreds of nets as even a modest Internet search will attest. ARRL and ARES-OK Internet sites list Oklahoma nets, however, the lists desperately need updating. Hopefully, the above info is accurate.
The very popular 7290 Traffic Net has many check-ins from Oklahoma, Texas and surrounding states. The net handles a fair amount of traffic. The Web Site for the 7290 Traffic Net is a valuable resource for traffic handling procedures and other operating aids. This net provides on-air training about once a month.
Websites for OKC, Tulsa, and Norman (W5NOR SCARS) radio clubs list additional nets along with valuable resources.
