A talkgroup started by a group of hams that frequented the Dayton Ohio repeaters in the early 1990's... The 511 represents the 145.11 repeater... the "nation station" as we called it. Also kept the midnight oil burning on the 147.135 farout repeater and the 146.82... go to bed kids repeater. Come on in and cut up with us... we were teenagers then. Now we have teenagers!
