I have two of these, both running DSB capable firmware, but haven’t tried it out yet because tuning by up and down pushbutton would be very tricky to actually work.

And yes, the transmit provides both side bands, so this would theoretically work.

Has anyone used the Quansheng UV-K5 or k6 (or other variants) on the satellites yet, especially the linear satellites? I see that there are now firmware mods to these HTs that not only allow for SSB reception-but also SSB transmission on 2m and 70cm. It is actually Double Side Band supressed carrier but several Youtube videos show it working well on 2m USB.

So, since the satellites conventionally use LSB for the uplink, wouldn't the DSB transmit audio also provide a LSB signal that would be inverted to USB by the satellite?

I wouldn't expect stellar performance out of these HTs but I do think a pair of them could make a budget friendly portable SSB station for some grid activations. Using them would be better than being QRT while in that grid because you couldn't afford a pair of FT817s or IC705s
