CW Skimmer

CW Skimmer

General

• This implementation loads and connects SmartSDR to CW Skimmer without using a virtual serial port pair. Connection is accomplished using TCP/IP and special Telnet commands.
• This feature only supports F6000 radios.
• This feature only works with Slices A/B.
• Optionally, VFO B can be set from a CWS waterfall or band map click.
• Optionally, the call sign can be sent to DXLab's WinWarbler when a CWS waterfall or band map is clicked.

Setup

• You must own a registered copy of CW Skimmer (v1.83 or later) which can be obtained from the DX Atlas web site.

DDUtil

• In the CW Skimmer group on the Features tab.
  • Select the Skimmer Close check box if you want CW Skimmer to close when the check box is un-selected or when DDUtil closes.
    • Not selecting this check box will cause CW Skimmer to be minimized when the check box is un-selected or when DDUtil closes.
  • Select the VFO B QSO check box if you want VFO B to QSY when a CWS Waterfall trace or a Band Map call is clicked in CWS.
  • Select the WinWarbler check box if you want WinWarbler's Call window to be populated with the Band Map call sign if the call sign is clicked.
  • Select the Enable check box

    • Enable the #1 stream by pressing the #1 button.
• Open the DAX item of the Panadapter controls group.
  • Select the DAXIQ Channel (1) set above.

Note: → Any DAXIQ Channel may be selected as long as the above settings and the CWS Skimmer Setup panel agree.

Operation

• Use CW Skimmer as you would normally.
  • Frequency control can be set from either SSDR or CW Skimmer.
  • If working a pile up and you have selected the QSY VFO B option when you click a station in CWS VFO B will be QSY'ed to that frequency.
  • Sometimes when CW Skimmer is first started, a Knob Bump is required to synchronize the CW Skimmer frequency display.
