Some of the cheap DVB dongles will definitely work to receive the telemetry from AO-73. You will probably be able to hear conversations on the transponder in the evening too depending on your antenna. AO-73 has a strong signal. You will probably be able to hear the transponder downlink from VO-52 as well.
