What does it take hardware wise and relative cost wise to add RDS to an
existing FM station. I am puzzled as to why the #1 FM station here in
columbus oh still does not have the RDS channel working.

It doesn't take more than a few hundred dollars to buy a box that just
generates a subcarrier with the station call sign.

But if you want to put actual useful information out from RDS, that can be
substantially more expensive.
