See link and discussion below.
But beware that the device is using a maxiumum clock of 300 MHz.
It uses first and second harmonisc to reach up to 900 MHz.
Its accuracy is getting worse all the time!

This is a firmware based on the original Edy555 firmware with some small
changes - Upper frequency limit is increased to 1500MHz. Be aware accuracy
decreases rapidly above 900MHz - A "scan" console command is added to allow
arbitrary sweeps with arbitrary number of points - The stack sizes of the two
main threads have been adjusted for increased robustness.(thanks to david
mugridge )
