Good comparison, the new ones have the extra range compared to Kiwis.
I just have a noob question though, about Kiwi radios. I use different ones regularly, and notice that many have their own custom configurations, like some have buttons for SAM, others do not, the same with narrow and wide AM modes, others have DRM buttons.
What I wonder is if you as the operator have the choice about what buttons are given, and what modes are supported? For example, I can't see DRM being useful in North America, so if I ran a Kiwi, I'd want to replace it with something more useful.
Can that be done, or is it mostly controlled by the Kiwi company, and can they push updates over your config? How easy would it be to customize buttons, modes, by graphical interface or script at the command line?
Thanks in advance! Some of the simplest questions about running SDR don't seem to be in the guides.
