The critical part is operational. The Pi Zero arrived today and I had a 16GB microSD card ready to go with Raspberrian Stretch OS. I did the update and upgrades then installed the WSPR software from the relevant GIT A few minor tweaks and it is WSPR-ing away on 6M. I did try it on 20M too although that isn't its destination. I revised the amp/filter PCB layout a bit late today with the hope of producing a PCB tomorrow and getting the SMD parts onto it. Obviously a bit of filter tuning to be done but maybe it will be ready early next week. Anticipating 400-500mW out on 6M WSPR.
