That's the answer! - thank you Daniele!

I didn't actually make the calls - just created them from the cluster as an import test - but the penny didn't drop that 7.3 MHz is of course way out of the IARU Region 1 band plan.

Changed them to 7.15 MHz and they loaded fine.

Thanks again and 73

How blind can an old man be .... Don´t checked out that the frequency was out of band .... Arrrggghhhhhh ....

It didn't occur to me, either! - thanks for all your help
