Ham Radio General Class Practice Test

Which frequency allocation is specifically assigned for amateur radio satellites?

1. 430 MHz to 440 MHz

2. 1400 MHz to 1450 MHz

3. 24 GHz to 24.05 GHz

4. All of the above

The correct answer is: All of the above

The frequency allocation for amateur radio satellites includes multiple bands and the correct answer reflects this broad allocation. Each of the ranges listed – 430 MHz to 440 MHz, 1400 MHz to 1450 MHz, and 24 GHz to 24.05 GHz – is indeed designated for amateur satellite communications. The 430 MHz to 440 MHz band is primarily used for satellite uplinks and downlinks, particularly in modes such as FM and SSB. The 1400 MHz to 1450 MHz segment is commonly utilized for satellite communications too, as it allows for digital communication modes. The 24 GHz to 24.05 GHz range is increasingly being utilized for advanced satellite operations, particularly in favor of high-speed data transfer. Thus, stating "All of the above" accurately encapsulates the existence of multiple frequency allocations sanctioned for amateur radio satellites, illustrating the versatility and scope of amateur satellite operations across different frequency bands. Each band offers unique propagation characteristics and capabilities that are beneficial to satellite communication.
