I have noticed that typically the S meter on the version one boards are " Scotch " compared to the version 2 boards. There are several changes to the S meter circuit, and if memory serves me right, the AGC circuit also, on the version 2. I have tried to update the earlier board with the new changes with mixed results. Since its strictly and issue with the S meter, and not receiver performance, I have learned to live with it.
