Master the Waves: Ham Radio Extra Class 2026 Practice Test – Tune In and Transmit Success!

A satellite operating in mode U/V typically means it is receiving on the UHF band and transmitting on the VHF band. In this context, the UHF frequency range designated for satellite operations falls between 435 MHz and 438 MHz. This frequency range is commonly used for uplink and downlink communications with satellites.

The selection of this band is important because UHF frequencies are ideal for satellite communication due to their ability to penetrate the atmosphere effectively and reduce the impact of weather conditions. The corresponding VHF band for transmission (which is not part of this question but provides context) is generally in the 144 MHz to 146 MHz range, where many amateur operators transmit to satellites. Therefore, identifying the correct UHF receiving frequency of 435 MHz to 438 MHz aligns perfectly with the common practices in satellite communications for amateur radio operators.
