Where does Rumlog put these error messages?
They scroll up to fast to read and there is no scrollbar
in the window to scroll to the beginning.
tnx. 73 Fernando N2FQ
There should be a scrollbar. The errors are not saved, or otherwise accessible except in this window.
A very common failure is a not correct set frequency table in the Preferences under the QRG/Mode tab. Make sure, these settings agree with the band plan in your region.
If you have further trouble, I could try it for you. Please e-mail me your ADIF file.
