SDRPlay RSP2 First Look Video

First Look Video of the new SDRPlay RSP2. Featuring a quick overview of the new features. The RSP1 and RSP2 signal comparison was done in realtime using the same antenna attached to the RSP1 and RSP2. This means that there is some amount of small signal loss due to the splitter. The RSP2 antenna was connected to the Port A connector on the RSP2 to make the comparison as even as possible. According to SDRPlay, the RSP2 Hi Z port can perform a bit better on AM broadcast and HF bands. To make things as even as possible both the RSP1 and RSP2 were used with the default settings for each radio. Of course both the RSP1 or RSP2 can perform a bit differently depending on the tweaks you make within SDRuno. Also performance of the RSP2 may change as SDRuno is updated to better leverage the new features of the RSP2.

SDRPlay RSP2 Review


If you have read our past articles on the SDRPlay RSP, you probably noticed that it has been a highly regarded SDR receiver here at HRS. It was named as the best SDR radio available in its price category. The SDRPlay RSP is even good enough to hold its own against far more expensive SDR products. Not to mention that it comes with excellent support from SDRPlay team. Over the past year, the SDRPlay got even better when SDRPlay acquired the excellent Studio One SDR software and adapted for use with the SDRPlay RSP. The new version of Studio One for the SDRPlay was renamed to SDRuno. The addition of SDRuno to the SDRPlay makes the RSP even a better value by adding a very powerful SDR program with a very attractive and professional user interface. Unlike some SDR programs that look pretty dated in comparison. The SDRPlay team continues to add new features and improvements to SDRuno on a very frequent basis. Not to mention that the price of the SDRPlay RSP has been lowered to $129 and is easily available in the US from Ham Radio Outlet. With the SDRPlay RSP’s low price, continous coverage from …

Icom 7300 Review


Last summer Icom announced a new radio that caused quite a stir in the amateur radio community. The new Icom IC-7300 was the first SDR HF / 6M direct sampling transceiver available produced by one of the “big three” manufacturers of ¬†amateur radio equipment. The announcement of the IC-7300 caused quite a bit of buzz, controversy, and anticipation amongst the amateur radio community. After approximately 8 months of waiting, the Icom 7300 finally landed on US shores in the later part of March of this year. The IC-7300 has made into the hands of eagerly awaiting amateurs to be put through its paces. So far the reports from early adopters have been nothing short of stellar. Some users are reporting that the ¬†IC-7300 easily matches or bests the performance and features of their existing high end “legacy” transceivers costing 2 to 3 times more than the IC-7300. Speaking of price the US version of the IC-7300 currently comes to $1499. The IC-7300 is considered to be an “entry level” transceiver, but that is really not the best description. The IC-7300 is really more of a high end transceiver in a lot of ways that offers a huge bang for …

Elad FDM-DUO – SDR Done Right!

The SDR-DUO has been on the bench in day to day use for about 2 months now so it’s time to talk about how it works out in “real world” use. The Italian made FDM-DUO has to be the most versatile, well designed, and well thought out SDR system currently on the market. With some of the major amateur radio manufacturers beginning to bring SDR systems to market, they would do well to take a look at what Elad has done here. The FDM-DUO can be used as a very pleasant and capable standalone transceiver as well as a very powerful SDR system when coupled with Elad’s brilliant FDM-SW2 SDR software. The FDM-SW2 software has to be hands down the best SDR programs out there featuring a wide array of useful features currently unmatched by other entries. It’s also nice to know that Elad isn’t resting on their laurels when it comes to software. Elad is continuously making improvements and adding new features to the FDM-S2 software. The FDM-DUO concept is exactly what a lot of radio hobbyist have been looking for. A pleasant easy to use standalone direct sampling SDR transceiver for times when you just want to …
