Sure. The most active repeaters for general chat stuff are 147.39 and 146.91 (Broken Arrow).
Also active and heavily used for storm spotting is 146.88 and the W5IAS linked system - 443.85 is the Tulsa node of that system.
There is also some traffic on a number of other repeaters - 147.045 and 146.805 are probably next in line for activity. The backup repeaters and the ones in the outlying areas are generally less used, but there are a couple that have a bunch of die-hard users. 147.06 in Pryor and 147.09 in Claremore are pretty active, but can be hard to hear in Tulsa depending on your location and antenna. If you're interested in a particular direction let us know, and we can get your more freqs.
Also check out the club web sites to get repeater lists (and updates on their status - several are down for maintenance at the moment)
