I activated 3 parks yesterday using the program on a MS Surface laptop. A lot easier to use than N1MM or N3FJP. No issues logging. Had to remember the program wants freq in Mhz, not Khz. Back home, and saving as .ADI. Mine did not automatically save as .ADI, they were saved with no extension txt. I then just renamed the files with .ADI and uploaded fine. Great program, hope he adds freq readout.
