Enabling CW Skimmer to Track and Set your Transceiver's Frequency

CW Skimmer can work with

  1. a wideband receiver like an HPSDR Mercury, Perseus, QS1R, SoftRock, SDR-IQ, or SDR-14 that is connected to an antenna

  2. a "3 KHz receiver" like those found in Elecraft, Icom, JST, Kenwood, Tentec, and Yaesu transceivers
  3. a wideband receiver connected to a receiver's IF

When using CW Skimmer with a wideband receiver that is connected to an antenna, enable it to track and set your transceiver's frequency by using Dick W3OA's Skimmer to Commander bridge.

When using CW Skimmer with a 3 KHz receiver or with a a wideband receiver connected to a receiver's IF, enable it to track and set your transceiver's frequency as described below.

Commander's Secondary CAT port can be configured to respond to CAT commands from CW Skimmer, enabling CW Skimmer to track your transceiver's frequency and QSY your transceiver via selections in CW Skimmer:


To configure Commander to interoperate with CW Skimmer as described above,

  1. establish a connected pair of virtual serial ports using VSP Manager or com0com; these instructions assume that connected virtual ports N and N+1 are created (e.g. 15 and 16)

  2. in the Secondary CAT Serial Port panel on the Config window's Ports tab,

    1. set the CAT protocol selector to Elecraft

    2. select Follow & Lead Primary

    3. set the Port# to N, the Baud selector to 9600, the Word selector to 8, the Parity selector to None, and the Stop selector to 1

    4. check the Enable box

  3. configure CW Skimmer
    1. open the Command menu and ensure that there is no check mark to the left of the Blind Mode entry

    2. select the View menu's Settings item to display the Settings window

    3. on the Settings window's CAT tab,

      1. select Use Radio 1

      2. click the Configure... button

      3. on the Omni-Rig Settings window's RIG 1 tab

        • set the Rig type selector to Elecraft K3

        • set the Port selector to N+1

        • set the Baud rate selector to 9600

        • set the Data bits selector to 8

        • set the Parity selector to None

        • set the Stop bits selector to 1

        • set the RTS and DTR selector to Low

        • set the Poll int., ms and Timeout, ms selectors to 100
