Re: What is "Decimation"?

Hi Decimation is a way to reduce the number of samples delivered to the software. I believe that the minimum sample rate of the hardware is 2M samples per second witch is huge for a software designed to use a top grade sound card limited to 192 KHz sampling but with at least 16 bits resolution. Here...

Re: SDRplay RSP1 gain control

Yes there is a strange thing with the LNA button on RSP1
It works definitely better with it on Long and Medium Wave .
That is rather unexpected but once you know it that is OK.
On VHF /UHF it improves SNR as expected.
On a crowded FM band it introduce intermodulation but that is normal too.

Re: DAB with SDRplay

Hi I believe the software is included somewhere in the drivers of the RSP1. It is not user friendly but quite sensitive. There is one for DVBT too but it is very CPU intensive due to every thing being done by software . It could be useful with a big computer anyway. May be ATSC is supported too ? On...

Re: EXTIO dlls for RSP2

Hi Am I the only one to think that the GUI of EXTIO dlls needs work ? It has a tendency to mask everything on the screen. There are too many linked boxes. The main window could show more useful information like use or not of up conversion and actual LO value. Depending on the software we use it is s...

Re: Android App??

Look here too: http://www.sdrplay.com/community/viewtopic.php?f=5&t=692&p=2784#p2784 To be honest as far as SDR is concerned I found that Intel based devices were much better than Android ones. I believe it is related to the huge mathematical computations involved. Anyway SDRtouch can be han...

Re: Got my RSP2 today! First impressions:

however the clock in/outputs are inviting me a lot to make some passive radar experiments, which of course means buying a second RSP2! Ka-ching! :mrgreen: Hi Thanks for this nice report. On that subject is there a software possibility to tune 2 RSP2 exactly the same way ? That could be useful. Shar...

Re: RSP1 with Win10 MiniPC

A few other tips: To spare USB ports I thought it would be clever to use a Blue tooth Keyboard and mouse instead of the one I am using that needs a USB dongle. Very bad idea they need to be paired each time you change machine or even OS on the same one. This requires a real keyboard. :twisted: Somet...

Re: RSP1 with Win10 MiniPC

No it is only 100Mbps but there is an USB3 port that should allow the use of an external adapter. I tried a low cost adapter mixed with a 3 ports USB3 Hub but had some problems of dis-connexion. Hub seems OK but doesn't allow an external power supply. For the power supply it needs 5V at 3A and there...

Re: Couple of SDRUno feature ideas :)

I would like to see an option to backup all your uno program settings to a file. That way, if your computer goes down, or you install on second computer you could load that backup and get right back to where you were. Hi Since a few weeks I use a trick that may be useful In order to use a mini wind...
