I have struggled to balance radio, paddle and phone when going portable. What seems to work best for me is putting down the radio somewhere, and holding the phone with paddle in one hand. I’ve built a little paddle and holder based on @VK3IL, the principle may be of interest to fellow screen loggers…
That’s really interesting. Does the bracket get hot at all?
Potential revision could be to make the bracket from 3D printed material and maybe have a section slightly sunk down a bit along the side so you could use some double sided tape and place a metal strip there to fit in place attach a paddle to?
In my case paddle stays at hand temperature, my phone doesn’t heat. Certainly a lot of improvements depending on personal preferences can be made. For me the choice was based on minimal weight (25g) as my portable activity is mostly an add on to hikes I make.
