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 …
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.…
With the release of the Icom 7300 a few months ago, a built in spectrum / waterfall display has become a very popular idea. The little Elad FDM-DUO when connected to a computer and the FDM-SW2 software clearly trumps the IC-7300 when it comes to the powerful features of PC driven SDR. However, sometimes something simpler might be better at times. This has been the charm of the “no computer needed” Icom 7300. The Elad FDM-DUO is also a standalone knob and button controlled SDR, but you lose the additional functionality of the Spectrum / Waterfall when operating standalone. Thanks to the hard work of Giavanni HB9EIK in cooperation with Elad you can now add a wireless bluetooth remote control scope to the FDM-Duo using an Android tablet or phone. The remote will allow for touch tuning of the Elad FDM-DUO via the the spectrum /waterfall display as well as change bands, toggle the PTT and Tuning features, and turn on and off various setting like noise Noise Blanker, Noise Reduction, etc. All with no PC required. Since the scope / remote is wireless, it can be placed in a more convenient location or operating position to allow for easier …
