G6A01 Explanation 1
Key B — 3.800 to 4.000 MHz
General class phone on 80 and 75 metres runs from 3.800 to 4.000 MHz. The 3.600 to 3.800 MHz segment is Extra class phone, and it is one of the most audible reasons operators upgrade.
Rule 47 CFR §97.301(d) - General class privileges
-
G6A02 Explanation 2
Key A — 14.225 to 14.350 MHz
On 20 metres the General class phone segment is 14.225 to 14.350 MHz, while 14.150 to 14.225 MHz belongs to Amateur Extra. Tuning into the Extra segment is a common and avoidable error for a newly upgraded operator.
Rule 47 CFR §97.301(d) - 20 metre privileges
-
G6A03 Explanation 3
Key D — 1500 watts PEP
The limit is 1500 watts peak envelope power, and the on-air requirement is additionally to use only the power necessary for the communication. A 100 watt transmitter with a good antenna routinely outperforms 1500 watts into a poor one.
Rule 47 CFR §97.313(a) - transmitter power standards
-
G6A04 Explanation 4
Key C — 3 kHz
Phone on 80, 75, 40, 20, 17, 15, 12 and 10 metres is limited to 3 kHz. An SSB signal is normally about 2.4 to 2.7 kHz wide, so the limit is comfortable unless the audio is over-processed or the transmitter is over-driven.
Rule 47 CFR §97.305(b) - phone bandwidth
-
G6A05 Explanation 5
Key B — CW, RTTY and data
The 7.025 to 7.125 MHz segment is CW, RTTY and data for General class operators; the 40 metre phone segment begins at 7.175 MHz. Reading the privilege and emission tables together is the only reliable way to answer this class of question.
Rule 47 CFR §97.305(c) - emission types by segment
-
G6A06 Explanation 6
Key A — Any licensed amateur designated by the repeater's licensee or trustee
The control operator must be a licensed amateur who has been designated to be responsible for the repeater's transmissions, but need not be physically present - automatic control is expressly provided for. The station's privileges still follow that operator's licence class.
Rule 47 CFR §97.205 - repeater station control
-
G6A07 Explanation 7
Key D — Volunteer frequency coordinators organised by band and region
Part 97 recognises volunteer frequency coordination as the mechanism for assigning repeater pairs, and the FCC expects operators to follow the coordinator's recommendations. Coordination is a recommendation rather than a licence, but operating outside it invites mutual interference.
Rule 47 CFR §97.205(c) - frequency coordination
-
G6A08 Explanation 8
Key C — Operate in a country with which the US has an agreement, under that country's regulations and the privileges of the US licence class
Reciprocity is a matter of agreement between governments, and it comes with conditions: the visiting operator follows the host country's rules and holds the privileges corresponding to the US licence class. Some countries require a permit or fee in addition.
Rule 47 CFR §97.107 - reciprocal operating authority
-
G6A09 Explanation 9
Key B — An amateur station located more than 50 kilometres above the earth's surface
The definition is a matter of altitude, not of function: more than 50 kilometres above the earth's surface. Satellite stations and the ISS fall inside it, and they operate under additional provisions covering telecommand, identification and coordination.
Rule 47 CFR §97.3(a)(40) - space station definition
-
G6A10 Explanation 10
Key B — Control of a station's functions by a licensed operator at another location, used for remote and automatic stations
Telecommand is one-way transmission to initiate, modify or terminate functions of a station at a distance, and it is how remote receivers, repeaters and satellite systems are controlled. Because it is one-way, it is one of the specific exceptions listed in section 97.111(b).
Rule 47 CFR §97.111(b) - authorised one-way transmissions
