I have parted company with my Elad FDM-S2 after buying an SDRPlay RSP1. I found this small, lightweight receiver as good as my Elad on HF but so much better on VHF. On VHF I was let down by my oft failing homebrew antenna so I have bought a new Diamond D130J Discone that is currently winging its way from Australia.
But wait……….there’s more! On the back of selling the Elad I have ordered an SDRPlay RSP2 that is touted to perform even better on HF than the RSP1! This receiver too is winging its way from the UK as I write so hopefully by the end of next week I will have a reasonable set up that covers 1kHz through to 2GHz.

A few days again the courier left me an SDRPlay at the front door!
This rather unassuming looking device packs a decent punch for the princely sum of USD$129 plus shipping, 10kHz – 2GHz!
On opening the package I was quite surprised at how light it felt and in reality it is just a PCB inside a plastic container with a USB port at one end and an SMA antenna connector at the other.
I’m not too sure why I wanted to buy one of these, but I think one of the drawcards was the software that SDRPlay provides for driving this little receiver. SDRuno is a version of that very costly Studio 1 product but having bought the rights from the owner SDRPlay now provides this free, and not just for the SDRPlay RSP1! I had been using the software with my v3 RTL-SDR and also with my Elad FDM-S2 and really, I quite like its GUI.
I had read a fair bit about the noise this receiver allows to creep into its insides but frankly, I’ve not had an ounce of problems despite using a USB cable with no ferrite chokes and sitting next to a desktop PC and two LCD monitors.
As for performance, it’s not got as low a noise floor as the Elad but that can only be expected for the cost. On one evening last week I was picking up aircraft over the Bay of Biscay talking to Santa Maria and as of yet I have been hearing all the stations that my Elad hears using the SDRPlay. The SDRuno software has sufficient flexibility to reduce noise, change gain settings but the one lacking feature is the ability to draw out the signal on the waterfall display visually. This makes me sometimes think that the signals just breaking contrast are too weak to hear but when tuning to the signal it is perfectly audible and adjusting the AF bandwidth I can make it a pleasant receiver to listen to HF signals with.
One very good feature of this is the wideband settings of between 500kHz and 8MHz. Mostly I find 2MHz sufficient on HF and this saves me having to adjust the local oscillator too often when browsing the more wider of the HF bands.
Of course there are the VHF airband signals as well, which was another reason I thought I might like it and testing with a poorly made homebrew antenna has shown much promise. This is where the 8MHz bandwidth comes in real handy!Read More
