For the RSP1 and RSP1A


When you push the SDRPlay button (figure 1), an I/Q signal will be sent through the TCP/IP server using rsp_tcp.exe. According to tests, it works with Windows 10 and probably earlier versions of Windows. Vista has been tested successfully.

The sampling frequency is 250 Khz but switches to 1 Mhz for all modes except ADS-B, which uses a 2 Mhz sampling frequency.

The default TCP/IP parameters are given below; they can be changed by clicking the Options (port/adress) button, which is found immediately below the SDRPlay button (figure 1).

  • The default address is 127.0.0.1. To use another server, paste the server IP address here
  • The default port is 1234. but it can be changed with the spin button. Valid values are from 1231 to 1250. This allows the use of several occurrences of Multipsk, each one connected to a different server and receiver.

If you wish to listen to the demodulated sound, click on the +Speaker button

Once you press the RX/TX Screen button, you can use the Transceiver form to control the frequency and gain. Note that the TX button on this form won't function (figure 2). In addition, references to Ham Radio Deluxe and Commander can be safely ignored.


For the RSP2 and RSPduo

Restrictions

  • The bias Tee control on the RSP2 doesn't work with this connection.
  • The RSPduo will only run in single tuner mode
  • Sometimes the above procedure (referred to as the direct method) works, sometimes not. The cause is currently unknown. If it doesn't work, follow the directions below (the indirect method)

Instructions

  • Using your favorite text editor create a batch file (with the extension of .txt) with the following command in it. It must reside in the Multipsk folder.

rsp_tcp.exe -E

  • The following options may be added
    • -P0 for port A (which is the default)
    • -P1 for port B
    • -P2 for the Hi Z port
  • Change the extension using Windows File Explorer from .txt to .bat
  • Execute the file
  • If you get a good return, start Multipsk
  • Press the SDRPlay button. You may press the +Speaker button to hear the demodulated sound
  • Press the RX/TX Screen button
