The Yaesu FTDX 5000 is now connected, it was the power supply. It was changed from a 2.5 amp raspberry pi charger to a 3 amp charger.
The radio connected 1st try, the only part to sort now is the audio and I think this will be a setting that needs changing somewhere that my carer will manage to find.
Thanks for all the help and support and hopefully back on the air soon
