I was thinking, what would really be ideal for SOTA. ?I’ve gone hiking a couple of times with the sbitx. ?Together with the antenna and batteries (a couple of old laptop batteries and an adapter I made for them), it barely fits in my backpack, not leaving enough space for a small laptop (which I don’t necessarily need anyway); but I did manage to squeeze in the external 7” touchscreen last time. ?That and a tiny Bluetooth keyboard made it work well to have wsjt-x and sbitx at the same time. ?But… what if it was smaller? ?I also worry a little about fragility; the encoders could get bumped too hard, or the touchscreen. ?(Which I could probably mitigate by designing a good case for it.) ?So I wonder if the zbitx could end up being smaller just because some of the analog RF stuff is separated from the audio board. ?I think the smallest-possible radio with similar capabilities as the sbitx might be a thing to work on. ?There are smaller touchscreens, like 4” with a suitable resolution (same or higher), and I’ve seen a case to put the pi and the screen into a box around the size of any other rpi4 case (with not enough space for a radio, though). ?I think I can eventually come up with a way to have a remote UI to run on a tablet, phone or small laptop, with the pi acting as a wifi access point, so that the modems still run on the sbitx and the display is still useful, but without having to cram everything onto that display. ?Maybe a pi zero would be good enough. ?(Not that the rpi is the only choice. ?There are so many. ?What about a mango pi, riscv? ?I think eventually we will see something like that with the proper risc-v vector extension, and maybe that will be useful for sdr. ?I will be looking forward to try writing some algorithm that makes good use of it some day.) ?A smaller box like that might be a pretty good SOTA setup. ?Otherwise there are things like the Lab599, but it looks like it doesn’t do as much as the sbitx does. ?(I’d need the usual audio/cat control setup for digital modes, if I can’t run arbitrary apps right on the radio.) ? But it has a reputation for being a really excellent receiver.?
