Are you sure? This would not make sense to have 4 separate uplink
receivers if only one couild work at a time. I thought the whole idea was
to let the 18% channel effeciency of aloha uplinks all add so that the
downlink was better utilized... Int his case 4 x 18% approaches 80% on
the downlink.
THey could not have designed a better digipeater! (unless You are right
and I am wrong...) Anyone know for sure?
