[BC] Class C DA

[Alan Gearing]

In addition to KYPA, KHCB in League City has been licensed to operate 
with a DA during nighttime hours.  Also, there is a CP for a new station 
at Dalton Gardens, ID, which is authorized for DAN, but ND during daytime.

And to respond to a comment Dana Puopolo made in another email:  A 
number of the Class C DA's have nulls less than the equivalent of 
250-watts ND.  As a case in point, the Dalton Gardens nighttime nulls 
are the equivalent of only approx 30-watts ND and the KHCB null is the 
equivalent of approx 140 watts ND.

Regards,

Al Gearing
