Re: SdRPlay RSPDX - Interface with Multipsk
Yes it is a bit fuzzy. I will consider that rsp_tcp V.1.1 is for RSPdx and V.1.0 for the other SDRplay receivers (with the same instructions as before), this to issue the 4.43.1 version this week.
Below is what will be proposed in the manual:
- If the "SDRplay" button is pushed, for any SDRplay receiver, the I/Q signal is taken from the key through the "rsp_tcp.exe" TCP/IP server. According to my tests, the "rsp_tcp.exe" server works with Windows 10 and, possibly, with previous versions (Vista for example), this depending on the files missing and to be downloaded from Internet. It needs a powerful PC. The sampling frequency is initially 250 KHz, then it is switched to 1 MHZ for all modes except for ADSB for which it is using a 2 MHz sampling frequency.
Moreover, the "+Speaker" may be pushed, to listen to the demodulated sound.
The "Transceiver" window on the "RX/TX" screen permits to control the frequency and the gain (see Transceiver).
To make this interface possible, several files are located in the Multipsk directory:
Moreover for the rsp_rcp.exe version 1.1 (thanks to SDRplay), compatible with SDRUNO V.1.4 (using API 3.07 instead API 3.06), and particularly aimed to make work the RSPdx model:
Associated with "rtl_tcp.exe" and "SDRplay", by pushing on the "Options (port/address)" button, it is opened a box in which it can be changed:
By clicking on the "RSP2 bias-tee", the bias-tee (4.7 V / 100 mA max at the ANT-B antenna output) of the SDRplay RSP2 (and RSPduo) can be set ("On") or reset ("Off"). Note that this option is not stored, by precaution. So, it will be necessary to configure this option at each Multipsk start-up.
About the RSP2 and RSPduo models (with the rsp_tcp version 1.0) :
If the direct interface with Multipsk does not work (with an error message), try this procedure (thanks to Christian and Fred):
1. start "rsp_tcp.exe -E" (from the Multipsk folder), with, for example, the "SDRPlay_RSP2.BAT" batch file in the Multipsk package.
2. start Multipsk,
3. press on the "SDRplay" button and, possibly, on "+Speaker" to listen to the demodulated sound
4. press on the "RX/TX screen" button
About the rsp_tcp.exe V.1.1 (rather aimed to the RSPdx model):
Push on the "Options (port/address)" button and then on the "rsp_tcp V.1.1" button.
It permits to directly make work all the SDRplay receivers RSPdx and probably RSPduo (but also the RSP1, RSP1A and the RSP2 and RSPduo models but control problems on the port selection), but it needs the installation of SDRuno version 1.4.

I'm very confused. The options port/address button isn't a part of the SDR DX instructions (at least the last set I saw), so it doesn't belong there.
