It is all back to normal now. The final frequency calibration has been done and transmits in the order 6, 30, 20, 17, 15 metres so a cycle time of 10 minutes for 6M - and each other band.
The new watchdog control is functioning and will reset the Pi if it doesn't produce RF within 7 minutes of the last detected RF, so should keep going even in the event of a Raspbian OS or WSPR software freeze. It certainly works if the Rasbian OS doesn't finish booting properly too - which it has done a few times.
There have been a few reports for my 6M transmissions but mainly locals (< 200KM ) as it appears that other stations previously monitoring 6M have ceased for now.
The reports on 30M have been astounding for 5W of RF, not as many on 20M but still diverse. An odd spot on 17 and 15M and typically within VK.
THE band to operate on say FT8 would have to be 30M at the moment. Propagation from here is happening world-wide for quite a bit of the day and night. Somewhat amazing.
I am toying with the idea of similtaneously transverting up one of the HF frequencies to 2M. Not too seriously as I have lots of other projects on the go at the moment and it probably wouldn't be of much use until later this year or early next year anyway. Back of the mind stuff only - though I do have a 25W PA block out of an old 2M mobile that could easily be pressed into service to get (say) 10W out and a new homebrew 2M transverter PCB project partially built up.
