More unusual SP traffic
So today on one of the SP "tactical" frequencies, either 155.565 or 155.625, there were some very unusual transmissions.
The first sounded like school bus or taxi company traffic, things like "He needs a pickup, his ride is here".
Later I heard transmissions between a unit identifying as 4F20 and an unknown dispatcher (not the 'regular' voice on 155.535). This transmission was to the effect of "10-38, 10-4 at the residence, verbal only"
This really doesn't make sense because Troop F does not have a zone 4, and they don't use 10 codes. Does anyone have any idea what this could be?
