       | Radio Direction Finding came up the other day, and that's one of

       | a project out there to provide an "off the shelf" coherent RTL-
       | SDR receiver array:

       | That being the successor to KerberosSDR:

       | Looking forward to getting my hands on a KrakenSDR later this
       | year, hopefully.

         | prototype is currently being built. We already have stock of
         | the long-lead time components (TCXO, R820,RTL2832U), and the
         | updated software is already working. The only downside is that
         | the initial production run will be for only 1000 units.

           | (approximate) idea how much the KrakenSDR units will sell
           | for?
