Re: Choppy/Stuttering audio across platforms.

Hi RF_Bandit, I would certainly try HDSDR. This has the lowest resource requirements for any of the packages that you mentioned. There are several potential causes for what you are seeing, but dropped USB packets as a result of buffer overflows is quite likely with the machines that you mention. If ...

Re: SDRPLAY MSi2500

Hi F1BJB, The reason why the DVB-T software places more CPU load with the RSP when compared to the RTL platform is because unlike the RTL, the RSP is a true SDR. The RTL chipset has a hardware demodulator for DVB-T, whereas with the RSP (based upon the Mirics chipset) implements DVB-T demodulation e...

Re: Plan for sdr# plugin

Dear 13dka, I think there may be a little misunderstanding here. The original post related to an update to the plugin to unlock the full feature-set of current SDRplay API, namely I/Q compensation and DC offset correction. Unfortunately, there is NOTHING that we can do to restore the lost functional...

Re: Plan for sdr# plugin

Dear CaptainNemo, We did look at a release 2.3 a few weeks ago that would have brought the latest API functionality to the native SDR# plugin. However, because of the way SDR# has evolved over the last few months, we conclude that the native plugin code in its current form is unmaintainable and real...

Re: The station name thing

Have you actually clicked the button on the main page of the ExtIO window?

If you don't actually click the button in the lower left hand corner of the main page above where it says:

SDRplay Ltd
Version 3.8 Build 0218

no pop out window will appear.

Sincerely

Re: SDRplay and Airprobe

Dear fe8769, I am a bit confused about your reference to the VTX3D card. We don't understand the relevance that this may have to the SDRplay RSP. If you are using the mirisdr driver, we should point out that this is an unofficial driver that was not developed by us or as far as we are aware by Miric...

Re: Spurious signals at low gain

Dear 13dka, The noise bumps you see at low gains are not actually a fault. They simply relate to the use of sigma-delta ADCs. These converters use a highly oversampled sigma-delta modulator to 'shape' quantisation noise from lower to higher frequencies. Decimation filtering is then used to increase ...

Re: Learning to use SDRplay for Inmarsat

Dear espam, I don't understand your comment. These questions ARE discussed on this forum as evidenced by the comments and inputs already contained in this thread. Jon was merely pointing out that there will be additional RSP users in the independent Facebook group. It is entirely your prerogative as...

Re: Low signal strength?

Dear Anders, it is hard to see the detail on your screen grab, but your IF gain slider appears to be at minimum gain. I suggest that you try the following setting as a starting point: AGC off IF gain reduction: 50 dB LNA On Zero IF mode IF bandwidth: 1.536 MHz If this doesn't help, please email: sup...

Re: images & co

Dear Captain Nemo, Can you let support (support@sdrplay.com) know what you primarily use the RSP for ((Bands of operation, signal types etc) and what application software you use (HDSDR etc) and we can look to see if there is a particular configuration for the RSP that will minimise image problems. ...
