SDRplay RSP1A First Look

Inroduction
SDRplay’s RSP1 has long been a great value in an entry level SDR platform for radio hobbyist looking to get involved in Software Defined Radio. The RSP1 has also been a favorite for adding spectrum displays to non-SDR radios or experimenting with SDR applications. The other advantage of the SDRPlay series is strong software support. SDRplay offers their own SDR program SDRUno which is a highly powerful and well polished SDR client that leverages all the features and capabilities of the SDRplay series. The SDRplay SDRs are also compatible with several popular 3rd party SSDR programs such as HDSDR, SDR-Console, and CubicSDR. Several PC platforms are also supported including Windows, Linux, Mac, Android and Raspberry Pi 3. SDRplay offers excellent support via their website and Facebook Page. In short, the SDRplay series offer a great value for an entry level SDR. The nice thing about SDRplay is the Jon Hudson and SDRplay Team are always looking for ways to improve the SDRplay platform, either through improvements in software or hardware. The SDRUno software is updated on a regular basis with new features and improvements. The RSP2 was added last year and offered hardware improvements and new features. Frankly, …

SDRPlay RSP2 Review

Introduction

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 …

Why Apple’s iMac May be the Best PC for SDR Applications

Introduction
Most radio hobbyist these days have a PC in the shack these days. Even though convenient and sometimes necessary these PCs can be the source of annoying RFI (Radio Frequency Interference). Of course with many SDR systems, PC’s are a necessary accessory. PC RFI is not limited to affecting SDR systems but also affect analog radios also. It’s just more obvious on SDR radio systems because the RFI can been seen on the spectrum / waterfall display. What causes this? Modern PCs can generate a great deal of local noise via it’s CPU and possibly it’s power supply. The other large RFI generator is the LCD display. Between the two, they can wreak havoc on radio reception. Modern PCs now usually contain multi-core processors that can generate a good deal of RFI. It really doesn’t help matters at all that most PC manufacturers use a large amount of plastic in the cases which allows RFI to leak out more easily. LCD monitors another large source of RFI are all over the place. Some LCD monitors only generate a small amount of RFI while others generate a good deal. All this interference can be seen and heard on your SDR …

Icom 7300 Review

Introduction

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 …
