SDRPlayIntf instructions

  1. Download and Install SDRPlay API 3.15 from https://www.sdrplay.com/api/

  2. Place SDRPlayIntf.dll in the same folder as SkimSrv.exe or RttySkimServ.exe . Any other DLL's in that folder must be removed.
    The log file will be created in the user's AppData folder.
    Ex)
    C:\Users<user_name>\AppData\Roaming\Afreet\Products\SkimSrv

  3. Start SkimSrv.exe or RttySkimServ.exe .

  4. In SkimSrv.exe, select the Skimmer tab. Set the Segment Bandwidth to 96kHz or 192 kHz (48kHz is not available) and select 1-5 frequency bands. Set the Number of Threads to 1-4.
    In RttySkimSrv.exe, edit the settings for 96kHz or 192 kHz, and 1-5 frequency bands.

  5. If you choose more than one frequency band, only a single band will be active at a time. The program will rotate through the bands, listening on each band for N minutes. The default is 2 minutes, and can be changed in SDRPlayIntf.ini.

  6. In SkimSrv.exe, verify that spots are being decoded.

  7. The default is a RSP gain reduction of 50 dB. If you need to change this, you can create a SDRPlayIntf.ini file in the same folder.
    Example:

[General]
RSPSerial=
GainReduction=50
RotationInterval=2
Antenna=B
HIZ=1
  1. If you have multiple SDRPlay RSP's, the first unused RSP found will be selected.
    1. RSP2/RSPDuo support code is not yet implemented.
  3. RSP1A/RSP1B has been tested.
  4. Run the RBN Aggregator to send spots to the RBN, or use Telnet to connect to SkimSrv or RttySkimSrv.
  5. It is recommended to connect the RSP directly to a USB port on the PC. (USB hubs are not recommended)
    14 RSPDuo cannot use two tuners simultaneously because the sampling rate is fixed at 6MHz or 8MHz. SkimSrv.exe needs to be 3.072MHz.

Instructions for Using Multiple RSPs

  • Support for multiple RSPs.
  • To select an RSP, write the serial number in RSPSerial in SDRPlayIntf.ini and start SkimSrv.exe, or start SkimSrv.exe with RSPSerial set to empty and the first unused RSP found will be selected.

Installation

An example of the SkimSrv folder layout is shown below.

D:\
|
+---SkimSrv1\
|      +----------SkimSrv1.exe (Rename SkimSrv.exe to SkimSrv1.exe)
|      +----------SDRPlayIntf.DLL
|      +----------SDRPlayIntf.ini
|
+---SkimSrv2\
       +----------SkimSrv2.exe (Rename SkimSrv.exe to SkimSrv2.exe)
       +----------SDRPlayIntf.DLL
       +----------SDRPlayIntf.ini

Settings

  1. To select the RSP, enter the serial number printed on the back of the chassis in RSPSerial as shown below.
[General]
RSPSerial=230100F834      <- RSP's serial number
GainReduction=50
RotationInterval=2
HIZ=0
image
  1. If RSPSerial in SDRPlayIntf.ini is empty, the first unused RSP found will be selected.
[General]
RSPSerial=                    <- RSP's serial is empty
GainReduction=50
RotationInterval=2
HIZ=0
  1. The serial number of the selected RSP will be written to RSPSerial in SDRPlayIntf.ini.
