Anyone like sdr radios? What is a good but inexpensive one?
If you notice in my post I said my favorite to use, and if I could only have one radio, it would be my WinRADIO Excalibur Pro G33DDC, and that is an SDR. Although my main listening desk has about 15 SW receivers at it 7 of them are SDR’s, and those 7 are used more than any of my traditional radios. Yes, I like SDR’s a lot. Although I have had, and still have, some great traditional radios SDR’s are what I use most.
Inexpensive SDR’s are a compromise. There ain’t no such thing as a free lunch. So you can get surprisingly good performance at a modest price in SDR’s, but you really do get what you pay for and so you will always have to give up features / performance with price. There are many SDR’s on the market today, dozens, so no way to describe them all, but I will hit a few of the ones I have used and have first hand knowledge of.
The cheapest way to get an SDR is with a DVB-T dongle, this is generally less than $25 shipped. The R820T will give you a native tuning range from about 25 MHz to about 1700 MHz. Of course that range does not cover SW. Adding an upconverter, such as the Ham-it-up will add the entire MW/HF range for about $75 more dollars. The Ham-it-up itself is under $50, but it comes as a bare PC board, so you need to mount it in a box. The software to use with this setup is SDR#. However, this entire lash-up, Dongle, Ham-it-up, and SDR#, is really not a plug and play situation. Many people have had trouble getting it all working properly, but once it is working it is an acceptable performer for casual listening, better and with more features than any portable, for a portable price.
The venerable old SoftRock Ensemble II RX is a killer deal as a native HF SDR. You can get one and have it operating (put it in a box and have a power supply) for under $120 USD, well under $100 if you build it yourself. However this is not a plug and play radio. It is sold as a kit, but you can get the board pre-built. In this later case then all you have to do is mount it in a box and provide a power supply. For me the preferred software for this radio is HDSDR, while not horribly difficult to set up this is, again, not quite plug and play.
Moving up in cost from that you get into the “complete” SDR’s, meaning you don’t have to finish them before you can use them.
One of the nicer combinations of feature set and price is the AFEDRI SDR-Net (one of the only SDR’s I will talk about that I do not own or have not owned in the past, but I have used one). For about $250 you get an SDR that is complete and with good features. It can be used with several popular SDR GUI’s, including SDR#, SDR-Radio Console, and HDSDR. It is not quite plug and play and some users have had minor issues getting the software running. Since there is no such thing as a free lunch it does NOT perform as well as some SDR’s with similar features, but it is the best combination of features and performance I have used below $400.
Going above this price point you get into some very good gear, but it is no longer what I would put in the “inexpensive” range. In general from this price point up the SDRs are very easy to set up and get running, and generally very stable.
The SDR-IQ is about $500, and while limited bandwidth by today’s standards it is very stable, very well supported, and very easy to set up. The WinRADIO G31DDC Excalibur is about $900 and is, in my opinion, the best under $1300 SDR on the market. The QS-1R Quicksilver comes in at about $900, and is good with some nice features, but you really need to add some pieces, and cost, before you get a great radio. The Microtelecom Perseus SDR is a very good performer and can be found between $1000 and $1200. While I consider the G31DDC Excalibur to be a better radio the Perseus is supported by more third party software.
Above the ~$1200 point you get into the very good and very full featured SDRs. In the hobby market and for listening of all types the best performing of these, in my opinion, is the WinRADIO G33DDC Excalibur Pro, the price varies a bit but is generally between $1600 and $1900. The RFSpace NetSDR (I also do not own one of these, but have used one) is a very good device, starting in price, with no options, at about $1500, loaded with options it can run nearly $3000. And things just get better in this price range and up, but that is far from the “inexpensive” you asked about
