   Hi Tony!   
      
   22 Sep 2019 18:40, from Tony Langdon -> Richard Menedetter:   
      
    TL> I bought one recently.  Seems to work really well, once calibrated.

   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 )
