I am doing a project that is to build the Cubesate ground station for our school.
mine TNC is KPC3+, and it is connected to transceiver ICOM 910H main data socket via 6 pin connector. From Hyperterminal in CAL mode I can Receive and Transmit, at least the lights are on respectively, so I think there is no problem with connection.
but in the Packet Engine Pro monitor I didn't get anything, I have tried to get packet radio signal from ISS by YEASU 817 with its own antenna during outdoor testing, indeed I heard the packet signal only a few times, maybe the time is too short for TNC to decode it? How does this setup work? Will I only get the decoded signal from TNC with VHF/UHF AFSK from transceiver? Can anyone tell me?
any help will be appreciated, thanks!
