1141FA KMCO Orlando Intl FL - 136.650 active 30 April 2020

Hi all,

1141FA looks like it recently went active from KMCO on 136.650.  It was first received on 30 April 2020 with 2 RR messages by different aircraft below.  Since then I have had references to it on 11 of 19 days.  At 312nm I see very little traffic directed to KMCO so the 30 April active date is approximate.

1141FA  136.650  KMCO Orlando Intl FL - 136.65 first received 30 APR 2020
