Extra exam question E1A09
Subelement E1, COMMISSION RULES· Group E1A · 47 CFR §97.313(l)
E1A09 · §97.313(l)
Except in some parts of Alaska, what is the maximum power permitted on the 630-meter band?
- A.50 watts PEP (peak envelope power)
- B.100 watts PEP (peak envelope power)
- C.1 watt EIRP (equivalent isotropic radiated power)
- D.5 watts EIRP (equivalent isotropic radiated power) (correct answer)
WhyOutside certain parts of Alaska, the maximum power permitted on the 630 meter band is 5 watts EIRP. §97.313(l) sets the 630-meter power limit at 5 watts EIRP for most of the US, with a higher limit carved out for parts of Alaska specifically, answer D. The PEP-based figures of 50 and 100 watts belong to other bands, and 1 watt EIRP is the 2200-meter limit, not 630 meters.
