What do you need to have all signals at all times? How urgently do you need things to update? If you're willing to accept a delay of up to a second, you can create 60 channels which all take turns transmitting data. If you accept longer delays, you can create more channels (2 seconds 120 channels; 5 seconds 300 channels, 10 seconds 600 channels, etc)

Each receiver can save and then constantly output it's corresponding channel's data for the rest of that time period while the transmission isn't being sent. Similarly, if you're transmitting pulse counts instead of a constant signal, you can count up each time period's total at the transmitter and send it as one big pulse.
