just heard bfd ladder 15 on 483.3125 R

sounded OK out here in the subways - didnt say where he was located -
maybe at Pru T station - 913 am edt

"Ladder 15 testing on MetroFire Red"

( come to think of it - I have never heard Arlington test on 483.3125
R (or any channel) from inside Alewife T station nor the storage yard
)
