I wholeheartedly agree re price / affordability. I run an old xp laptop at home but can do all digital modes in the bush /p bar CCW aprs and winlink - however pat looks like a goer on the pi with ardop. You don’t have to go far from major capital cities in VK to have no mobile phone service. For me I wanted the short message capability as well as camp site location posting that ccw offers. I too tried exagear.
Sadly anything bigger than the pi form factor (and 5v Power ) is pushing it.
