I am using the latest version of sdr uno, 1. It's probably only a few hundred kHz, so I normally set the sample rate to 2 and the DEC to 4 or 8 You can also type in a VFO frequency into the RX control window or you can use the mouse scroll wheel in the SP1 Main SP panel to set the rig VFO frequency. Apr 13, 2019 · Go to the decimation DEC window if you are in LIF & set it at 1 or, if you are in ZIF set SR window to 10 & DEC window to 1: you will get the 10 MHz, but beware your PC is powerful enough and your RAM at least 4 gb, otherwise audio will start stuttering and finally SDRuno will crash.

I don't know why I did soI just thought I would give it a try. And in each decimation by 2 stage use a half-band FIR filter. This is what is meant by recording in I/Q format. 2. What I've noticed is as I increase Decimation, the tuning indicator moves to the right in the Main SP panel. 14 Using the custom controls. • Main panel version tooltip now displays correct information. SDRuno is the official software for the SDRplay line of low cost software defined radio devices. These features allow users to tune filters to avoid ADC overload and to overall fine tune reception better, especially for narrowband signals. 1 for RSP2/RSP2pro Antenna Selection Bias-T On/Off Reference Clock In/Out AM/FM Notch Filters SDRUno Version 1. 13 and older) These are our older SDRuno Video guides but specific topics are still relevant and only minor differences may exist with the Jul 2, 2016 · Over on his sdr4everyone blog author Akos has uploaded a tutorial that shows how to set up the recently released SDRUno with the RTL-SDR. You should see these roughly central in the panel. An example on 693 kHz of Main SP Offset (with ZIF) is: Offset(Hz) at SR: ===== Dec 2M 4M 8M === == == === 1 28 60 100 2 13 ? 4 6 15 8 3 7 16 2 3 32 1 2. In the interview they discuss various new features and improvements to SDRuno, the official software for SDRplay devices. SDRuno – V1. Try it with a lower decimation value. Jun 28, 2016 · I can run both tuners in SDRuno with a total CPU load of around 30%. I was using a laptop with a spec which certainly exceeded the forgoing minima, using Windows10 and SDRuno to run a RSPduo together with a RSP2 and simultaneously with a good quality RTL device under SDR#. Sep 19, 2016 · SDRUno, the official software for the SDRplay has recently been updated to version 1. The main change to the SP1 display has been to separate the resolution bandwidth (RBW) control from the zoom function. Feb 14, 2017 · Over on the Utility DXers file section at udxf. I'm using it on the original sdr1. Jan 5, 2017 · Decimation is a way to reduce the number of samples delivered to the software. What's also very interesting is their road map which states that future versions of SDRuno will have frequency scanning capabilities, a remote Aug 16, 2020 · SDRPlay Independent Community Forum › Forums › SDRUno › IF Mode Selection missing V1. Sep 22, 2016 · Over on YouTube two new videos comparing the reception on the SDRplay and Airspy have been uploaded. Probably the ADC sampling rate is fixed and decimation is done in the hardware, drive routine or SDR software invisible to the end user. Yes it can be changed in Win 10 settings but that's not the point. B. and in IF Mode select LOW-IF and put Decimation to 8 in the Decimation window: the interference will disappear. 1 using a RSPdx SDR. Mar 3, 2025 · Increasing the decimation in SDRuno does not lower the noise floor of the receiver. Tried a freshly-booted instance and it works ok on the AM preset. What's also very interesting is their road map which states that future versions of SDRuno will have frequency scanning capabilities, a remote In SDRuno, you select the ADC sample rate and apply decimation to give a final sample rate. 1 Application instance SDRuno can run in multiple instances, each with a different input device. We will be producing the “ook ook Plus” which will be available via Amazon in the very near future, this will cover what’s in this guide and also how to set up the various programs that can be used with SDRUno, such as CSVUserlist, Multipsk, WxtoImg, WSJTX, FLDigi, and many more. - click on: "Restart API service". Dec 30, 2016 · Yes, everything seems normal except for one thingwhen I set the SR to a bandwidth of say 4 MHz and and the decimation to say 2, I would expect a span of 2 MHz, but I get 1 MHz. 1 RSP1/RSP2/RSP2pro & EXTIO 1. He goes on to demonstrate the YADD GMDSS DSC decoder running via the HF audio piped in from SDRUno and Dec 30, 2017 · You can adjust the sample rate and decimation to better fit the IF output port bandwidth. com/rspdx/https://www. This means that the specific features of a particular SDRplay RSP receiver model are enabled automatically within SDRuno. Oct 21, 2020 · In this video Mike shows the basics of SDRuno v1. This is great if for example you wish to automatically record a shortwave programs playing overnight. The SDRplay RSP2 is the successor to the RSP1, and is a 12-bit SDR with tuning range from 10 kHz - 2 GHz. The span seems to be less by a factor of 2. I STRONGLY REQUEST that the step size for EACH MODE be user Decimation of Samplerate is an option for very old and slow computers: Before decimation, a very simple and fast low-quality filter (sum) is applied: y(k) = sum over x( k * (1. Is there any documentation that describes things like the difference between Low IF mode and Zero IF mode, the meaning of the "decimation" setting in the Main control panel, best settings for RBW, and how IFBW and Final SR interact? Jun 19, 2016 · SDRuno comes with a full manual (pdf) and SDRplay fans and beta testers of SDRuno have also released a free SDRuno cookbook guide (pdf). The interface exposes the ability to manually adjust the filtering within the R820T A simple, and efficient, solution to decimation by 8 is to perform three separate stages of decimation by 2. Whether it would also set a low sampling rate for the ADC is another thing. The diversity feature works with the Mar 15, 2019 · I'm having problems as well in trying to scan anything in the FM/VHF band. SDRuno implements some custom controls specifically created for it. decimation) ) ; x() = input samples from rtl_tcp; y() = output samples to SDR app (HDSDR) The sum produces values requiring more than 8 bit. the navtex and the rtty plugin. Decimation – The sample rate can be decimated by either 2, 4, 8, 16, 32 or 64 to achieve better noise performance. I'm using an RSP1a. My second observation is that changing decimation affects the measured carrier frequency. 2 of SDRuno is now released. The default input device is the SDRplay RSP but the input device can also be a soundcard (WME or ASIO), a pre-recorded IQ file or an I sometimes run SDRUno on a rather elderly laptop that is not really up to the job and I find that increasing the decimation is the only way to avoid breaks in processing. fallows. SDRuno Video Guides (V 1. That stopped the audio cutting in and out. 41 of their SDRUno software platform. 1 Setting the samplerate The implementation uses a sample frequency of 12 KHz, similar to e. 01. This means that the maximum span is 5 MHz instead of 10 SDRplay family is 2000000, a lot of decimation has to be done. It includes the much requested full scheduler facility which allows you to set up numerous recording events for your RSP. 41 released today. Biais de sélection Decimation, only values allowed can be selected. I cannot for the life of me recreate it (on purpose). 4) several times, but still confused. The one limitation is that the maximum SDRuno is the official software for the SDRplay RSP line of receivers, and the beta can be downloaded from their website (note the plugin will not work for the RTL-SDR). May I offer a sort of addendum to the forgoing post by glovisol. Here, the offset is roughly in inverse proportion to decimation. SDRUno V1. The default width of the spectrum scope is 2 MHz. In the standard drivers the tuner bandwidth is normally set at a size appropriate for the Sep 22, 2021 · Last week SDRplay released version 1. SDRuno Software Fig. SDRuno is also compatible with the RTL-SDR.
