Re: SDRUno recording settings?

If your signal of interest is 7012kHz and you are using a 2MHz bandwidth you could place the LO at say 6500kHz, well out of the way, although I guess if the LO were placed at 7000kHz you'd get the same result. Just put the LO a few kHz away from your SOI and you should be good. This applies to all t...

Re: RSP2pro vs cheap RTL ?

I'm going to jump in here and echo the findings of @wireman. I'm only talking here about HF frequencies but I found that the RSP2 yielded little if any difference to my sight or ears versus a v3 RTL-SDR. As an experienced HF listener dx'ing aero I've had a few receivers in my lifetime but nothing re...

Re: RSP2 Recording

Panic over! I was trying to record to a networked share and even though I have a full 100Mbps network the final leg was from my router to a USB2.0 device where all my home networked files reside. Even though I would have thought the throughput rate would sustain a recording at 200kHz bandwidth perha...

Re: RSP2 Recording

I should add that the subsequent recordings also stutters which makes one half of my use for the RSP2 a bit fruitless.

I did another test at VHF and just 200kHz but got the same result as my first posting.

Re: RSP2 Recording

Yes, 2MHz is much worse, the chuffing is about once every 2 seconds or so, and no audio in between. There's a video of this at https://hfaero.com/downloads/chuffing.mp4 showing 2MHz and 2MH with 8 decimation. A check of the Win10 Performance Monitor at 2MHz with decimation 8 shows one CPU at about 2...

RSP2 Recording

I've had a few goes at listening to my RSP2 while recording and it continually 'chuffs'. By this I mean the audio cuts in and out at a rate of about 2Hz (twice per second). I'm recording at full spectrum bandwidth but only at a 2MHz rate decimated by 8 giving me an effective RF bandwidth of 200kHz. ...

Yup, perfectly, from 1MHz up to UHF, after my frustrations here: http://www.sdrplay.com/community/viewtopic.php?f=5&t=1692#p5204!

Re: Android App??

Have you peeps looked on the SDRPlay web site recentl? Perhaps here at http://www.sdrplay.com/android.html

I can't vouch for it as I don't have an Android tablet but the demonstration seems to work OK albeit with an RSP1, I'm not sure of the RSP2 yet though.
