AO-51 did it (two simultaneous FM xmitters)—but hardly a cubesat!!

Hello Ray
Nice idea. channelized receive is fairly easy without excess power consumption. - single downconverter with multiple IF's or SDR equivalent. The main issue is on transmit where you need to share the limited 'DC power' between multiple transmitters. Probably possible to do 2 x transmitters on a 2U and 3 x transmitters on a 3U. Some fancy final amplifier running a high efficiency mode like class D or E shouldn't hurt the power budget too much

Behavior mod on the part of veteran FM ops doesn’t seem to be in the cards. So what about this? Suppose the next gen FM birds were channelized? That would divide the number of ops per pass. Thoughts?
