We DID decide not to \nuse it for the digital package.\n\nWe need to decide on whether or not there will be an L-uplink for the \nnarrow band package or a dedicated L/S TSFR package.\n\nI'd like to at least discuss, and maybe decide whethe or not to fly an L \nuplink on the command/analog channel. Bob and Rick are proposing \nOFFERING a L/S package to be developed by others and flown in a TSFR \nspace if it qualilfies. I see this as no cost, huge gain in both \nperceptions and capability.\n\nPlease join tomorrow and comment. I want to hear your thoughts!\n\nThanks & 73,\nJim\[email protected]\n\n\nLyle Johnson wrote:\n\n>>> We offer that anyone willing can develop and submit for \n>>> testing and qualification a stand-alone L/S transponder to fly in \n>>> one of the TSFR slots, using fixed antennas.
