Julian's video work is always very good, and very relevant to a lot of people. Investing in a home station can be nice - provided someone doesn't come along in the neighbourhood and install something that ruins it all for you. This happens to most of us, sooner or later. Much better to stay fleet-footed and ensure you can enjoy radio from wherever you want to go. I'm able to operate FT8 from one of those supposedly 'hopeless' 1/4 wave verticals at about 15-20W, or the same output I use back in the home station, in a field shack, also using a Raspberry Pi and 7" touchscreen. The UK is not noted for its sunshine, but a 100W panel keeps me going just fine, even on a less-than-blue sky winter's day. Radio is what you want it to be. There are plenty of people who want to shout that you can't operate PV portable, but that's usually because they've never tried, or too attached to big, power hungry operation.
