SOTABEAMS has issued a major firmware upgrade for their WSPRlite antenna testing system.

Since its release a little under two years ago the WSPRlite system has become a popular way for DXers to compare antenna systems.

The upgraded firmware allows users to transmit compound callsigns such as F/G3CWI and also to transmit six character grids. WSPRlites will run directly from an Android phone. The phone provides timing and position information. This combination, together with the firmware upgrade, makes a handy pocket-sized package to take on holiday for some ham radio fun from the beach!
