Software Defined Radios (SDR): SDRplay RSPdx vs NOOELEC Ham It Up

What antenna is he using

I should use this to fall asleep when I had coffee too late in the day

Using direct sampling on the RTL, or just the RSPdx is a far better configuration than using an upconverter.

When on the upconverter, you have two frequency offsets to contend with: the converter's and the dongle's. They drift differently, so you get an oddly trending offset to enter into your software. At one time, you might use 125.00130 megs, and an hour later it is 125.0020 megs. Not a big deal for AM signals, but way too much for SSB, CW, or digimodes.

Those spurs in the AM broadcast band, and elsewhere, are a key reason why a native lowband SDR is a better rx method than using an upconverter. You have added another oscillator and mixer, plus another front end where intermod happens.

Then, on the SDR, you have the issue on sampling rates.. Higher rates should fix the problem of aliasing / fake signals.

I have the SDR Play RSP DX and a Adalm Pluto SDR,

Great video great job and great comparison….but I have a few questions…The comparison it’s not on same frequencies and the nooelec gain isn’t on high!
So…. I would like to khew what is your opinion about these two receivers…
Which is better….
what is your suggestion?
Nooelec or Rsp….
So My opinion….I think that Rspdx has less mirrors and less overloading with hi gain but nooelec has a better receiver and more overload’s with hi gain!
Thanks anyway!

This video would have been better without the background music...

I use an RTL-SDR V3 with the Ham It Up on HDSDR software and do not get the heterodyning effect! Thanks for the video!!!

Thank you for trying, but failing to use the proper software offset suggests you do not know how to set the RTL dongle system up properly. Moreover, failing to demonstrate each product on the same software platform - such as SDRConsole that runs both rigs- makes it difficult, if not impossible, to fairly and accurately compare the performance of each product. For example, using a single program for both rigs will allow us to measure and realistically compare the noise floor, signal level, Singna-to-Noise ratio, RFGain, and other products of each product. Perhaps you could pull this video, and replace it with one that is more helpful? Good luck and good DX to you. JT

I believe you can enter the 125 MHz offset into sdrsharp and then read the HF freq directly instead of doing the math in your head.

Some links to the products you are using would be most helpful so that we can go and compare specs and pricing . Thanks

thanks for the comparison

Thanks for the comparison! I was wondering which to get...
