UHF is more robust than VHF (was Re: Digital TV receptionproblem)

[Rick Levy]

Per Dan.Strassberg,
>>
...it doesn't necessarily follow at all that 60 kW digital is less than 300 
kW analog." Does anybody have a conversion formula?<<

The standard ratio of peak to average power (with standard black picture) is 
1.68:1.  Thus the 316 kW peak power previously licensed to WHDH was 
equivalent to about 188 kW of average power.

I believe the doubling of DTV power was (in round figures) from 15 to 30 kW 
ERP, not 30 to 60, and that the 30 has already been achieved.
