UPDATE 2020_09_02:  The CW skimmer station was rebuilt in late 2017 based upon the then new Red Pitaya hardware platform.  The Red Pitaya system at W4KAZ currently operational is described in the post link below:

 NOTICE: Historical skimmer station information below.

The W4KAZ skimmer station feeding spots to the Reverse Beacon Network was switched over to use a Red Pitaya as an SDR in November 2017.  The following information describes/documents the previous skimmer that is NO LONGER THE ACTIVE STATION.  I’m keeping it only for  reference purposes.

The following are a set of links which develop a bit of background history on the planning and construction at W4KAZ of the CW skimmer station.  It is designed to use the SoftRock SDR kits and VE3NEA’s CW Skimmer program to feed CW spots into the Reverse Beacon Network.

Currently there are SoftRock CW skimmers completed for the 160m, 80m, 40m, 20m, and 15m amateur bands.  Construction of the 10m SoftRock is pending.  Revisions to the softrocks for 20m and 15m are planned, pending the success of the 10m kit.
