US Naval Academy HFsat Coordinated for 15 Meter-to-10 Meter Transponder

The US Naval Academy has received IARU satellite frequency coordination for HFsat, a 1.5 U CubeSat with a 15- to 10-meter linear transponder with a 30 kHz bandwidth (uplink 21.4 MHz, downlink 29.42 MHz). The Mode K configuration is reminiscent of the old “RS” series of Russian satellites.

The CubeSat will also carry an APRS digipeater on 145.825 MHz. HFsat is a project to demonstrate the viability of HF satellite communications as a back-up communications system, using HF radios found in a typical Amateur Radio installation or frequently used to support disaster and emergency response communication.
