Lately I have been noticing call signs such as "Road Runner", "Ram Rod", "Ping Pong", etc on the COTHEN network. Where did "Hammer" go? When searching Google I did stumble across Lindsay's Drug Interdiction Callsigns List
Well I don't monitor COTHEN but Hammer is still being used by MarchAFB on the Blue-3 (350.025MHz) here in San Antonio.
road runner i believe is tuscon HS/customs air ops, Ping pong is corpus christi air ops I don't know ramrod but it could be san deigo, new orleans, homestead, cuba, or panama.
