General exam question G1E08
Subelement G1, COMMISSION’S RULES· Group G1E · 47 CFR §97.313(j)
G1E08 · §97.313(j)
What is the maximum PEP output allowed for spread spectrum transmissions?
- A.100 milliwatts
- B.10 watts (correct answer)
- C.100 watts
- D.1500 watts
WhySpread spectrum transmissions are limited to 10 watts PEP output. §97.313(j) caps spread spectrum transmissions at 10 watts PEP output, far below the standard HF power limits, reflecting how spread spectrum's wide bandwidth and low power spectral density are meant to coexist with other users, answer B. 100 milliwatts undersells the actual limit, and 100 or 1500 watts both exceed it substantially.
