Going back to 2.4.10 from 2.7.3 How to do it?

Lasse SM5GLC

Have been testing the new 2.7.3 f/w for few days and it is vastly improved vs. the old 2.6.2 Timing for CW is so much better and allows for high speed sending with-out having to be embaressed.

BUT......

The spurious power drop-out is still there, less than on 2.6.2, but it happened twice in my last QSO and had one in the previous QSO. This is a show-stopper and for keeping my sanity I need to drop down to 2.4.10. Any instructions on how to do this? And yes I will open up a ticket for the ongoing power issue.
