New Software Support for SDRPlay RSP2

If you are the owner of the fantastic new RSP2, you now have a few more options as to what SDR software you can use it with. Besides the SDRUno software that was developed for direct support of the SDRPlay RSP series, SDR Console Version 3 developed by Simon Brown will now support the RSP2. SDR. SDR Console is very nice SDR program with a clean user interface and loaded with features. Also HDSDR now supports the RSP2. HDSDR has been around a long time and offers a simpler approach to using SDR radios. The user interface is very straightforward and friendly to beginners as well as experienced users who appreciate a fast and easy interface to a SDR radio. If you download the HDSDR software from SDRPlay’s website, it comes with the EXTIO files you need in the installer. So it’s pretty much plug and play. With a great choice of SDR packages the SDRPlay RSP series of SDR radios continue to be one of the most flexible SDR radios available today. Not to mention a great value.…

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 …

Adding Streaming Audio to BLUEDUO

This is a follow up video for adding streaming audio via WiFi to the Android based BLUEDUO remote display for the Elad FDM-DUO.This is accomplished by using the Soundwire audio streaming Android app. You must also install the Soundwire server application on a PC or Raspberry Pi. The audio stream from the FDM-DUO can be accessed via the TX USB connection. It is not necessary to run the FDM-SW2 for the streaming audio nor for the use of the BLUEDUO Android app. Doing so will confuse the BLUEDUO app running on your Android device. Once this is setup you can then use the BLUEDUO app and the Soundwire app to listen to and control the FDM-DUO from a remote location in your home as long as the location is in range of your bluetooth and wifi signal.The paid version of Soundwire will give you additional options for tweaking or reducing latency depending of your particular WiFi setup for best performance. However, increasing latency for better streaming performance may make the BLUEDUO’s scope appear a little behind the spectrum / waterfall. It’s best to try to reduce the latency to it’s lowest level while maintaining good streaming audio quality.

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 …
