I am looking for a HF SDR Receiver for $300.00 max. What are my other than
Air Spy +Discovery if any?
Air Spy +Discovery if any?
HF SDR
- Thread starter shirsch101
- Start date
Any particular model??
I have the Duo and the now discontinued RSPdx. Great little SDRs

Do you honestly want HF only, or is it HF "mostly", but still want to mess around with other possible signals outside the HF range?
Another option for you, in your price range, is the RSPdx-R2, or the RSPduo.
The Airspy HF+ Discovery is a good option, but somewhat limited in both bandwidth and tuning range. The SDRPlay RSPdx-R2 is not quite as good as the HF+, but most people will never be able to tell the difference in performance. And the RSPdx-R2 offers much wider IBW (10 MHz vs 660 kHz for the HF+) and much greater tuning range (up to a max 2000 MHz vs 260 MHz for the HF+, with a gap from 31 - 64 MHz).
I do not have the RSPdx-R2, I have the original RSPdx, but I have used the -2, and it is a slight improvement over the original. I am primarily an HF guy. If I had to choose between my RSPdx and my HF+, I would give up the HF+ first and keep the RSPdx. The other features it (RSPdx and RSPdx-R2) brings to the table outweigh the very slight performance delta.
OK, but I mentioned the RSPduo above, and then never talked about it. The RSPduo is what I would keep over either the RSPdx or the HF+. It is not as HF focused as the other two, and so not quite as good on HF specifically (still pretty darned good, just not quite up to the other two), but the dual sampler allows for some interesting playing around, such as diversity tuning, additive noise cancelization, and digital beam steering.
T!

Thanks for the info
Other than an Airspy Discovery+, I can't think of a better one out there presently for LW/MW/HF. Years ago I had a Ten-Tec RX-320 which was an excellent performer.
The new Mlite 880 looks promising for the price. The waterfall display is a definite plus.
Has anyone tried the Web-888 SDR
Ok which is better for HF…
SDRplay RSP1B or Airspy HF + Discovery?!??
SNR range on the Airspy HF+ is better than the RSP1b. You can hear weak signals a bit clearer on the Airspy HF+. I own both.
The Airspy HF+ can receive WWVB on 60khz but I had issues with the RSP1b because I used the YouLoop to receive WWVB 60khz on the Airspy HF+ but the RSP1b's MDS, Minimum Discernible Signal, isn't good enough to work with the YouLoop.
If you value DX then Airspy HF+ hands down.

You probably do not want to hear it, but no other will be as good. I have just about ll of them.
