What would you think of a sat that required no user frequency control for uplink or downlink and carried somewhere between 10 and 30 simultanious conversations? Here's how it can be done and it's a mode that I think deserves more investigation - ACSB, possibly with a twist. for those not familiar with ACSB, it's essentially SSB with a subaudable tone inserted. on recieve that subaudable tone of known frequency can be used for tuning and doppler adjustment. Taken a step further one could use the on sat beacon as the reference "tone" and simply maintain a frequency exactly a certain distance from that. come to think of it we could experiment with this now on the ssb birds we have now. anyone interested in trying this? has it been tried? what do you think?
