High End Per Vices Cyan Software Defined Radio Released

This blog is mostly concerned with software defined radios that are affordable to most hobbyists, but if you've ever wondered what the cutting edge is, take a look at the recently released Per Vices Cyan. This is a US$73,500 one channel RX/TX SDR with a tuning range from 100 kHz up to 18 GHz, ADC resolution of up to 16 bits, a maximum instantaneous bandwidth of up to 3 GHz (with 1 GHz per channel), and an on board Stratix 10 FPGA. There are also higher end Cyans, with the Cyan Mid having 8 RX/TX channels for USD$149,500, and the Cyan Pro with 16 RX/TX channels for USD$289,000.

Obviously Cyan is aimed at the research, industrial and possibly military market, but maybe this is the sort of capability we will all have in 10-20 years.

Their press release reads:

SignalsEverywhere Tutorial: Updating LimeSDR Mini Firmware and Installing Drivers

Over on his YouTube channel SignalsEverywhere, Corrosive has uploaded a tutorial video that shows how to update the LimeSDR firmware and drivers. The LimeSDR Mini is a US$159 12-bit TX/RX capable SDR that can tune between 10 MHz – 3.5 GHz, with a maximum bandwidth of up to 30.72 MHz. The specs and price of the LimeSDR mini are pretty good, but documentation for actually using it can be a bit confusing, so videos like Corrosive's tutorial are great.

MIT Radio Society Lectures on Radio Technology Now Freely Available on YouTube

At the beginning of this year the MIT Radio Society held a series of nine lectures all about radio. The lectures cover topics like the history of radio, radio technology, signal modulation and phasor analysis, software defined radio, ionosphere, shortwave radio, propagation, radio astronomy, low frequency radio astronomy for the observation of exoplanets, principles of radar, space weather and 5G cellular comms and the future of radio. The lectures have all been uploaded to YouTube for free viewing, and can be found on their playlist.

If you're interested in learning more about radio this series of lectures is an excellent start, and lecture three specifically focuses on software defined radio.

XRIT Decoder Updated: Improved Image Quality and IR Enhancements

USA-Satcom is the programmer of XRIT Decoder, which is a popular (paid) Windows decoding application for GOES weather satellites. With a WiFi grid dish antenna, LNA and SDRplay, Airspy or even an RTL-SDR, high resolution full disk images of the earth can be downloaded from these geosynchronous satellites. Browse through our previous GOES posts for ideas and various tutorials about setting up a receiver.

Recently, XRIT decoder has been updated and now has improved image quality and an antenna alignment helper tool. A further update also adds improved processing for IR images. Over on the SDRplay forums RSP2user has been testing the updates and writes:

USA- Satcom has just released version 1.4.6985 of the XRIT Decoder software package. New features include:

1) Improved image clarity.
2) An antenna Align Mode feature.
3) And a Viterbi and Eb/No (Energy per Bit to Noise Power Spectral Density Ratio akanormalized SNR) graph over time feature. 

The improved image clarity reduces image artifacts at the Earth-space boundary of the image and improves the overall aesthetics of the colorization of the full disk images. The images are quite amazing. The resolution is far better than what can be shown here due to image size limitations for this site. Below is a full disk GOES 16 image from February 17, 2019 and a corresponding zoomed in portion to get an idea of the resolution and clarity (the actual full disk images are approximately 40MB PNG images each which are much greater resolution than the below image)

The antenna Align Mode is a great new feature that allows users to view the Signal Quality, Viterbi FEC, and Eb/No from a distance using large numeric values. This mode enables users to better view these values when fine tuning adjustments to GOES receiving antennas. The Eb/No and Viterbi graphing enables users to see how well their receiving system is doing throughout the day (e.g., over temperature and while the sun is in alignment with the receiving path).

More updates from USA-Satcom to the XRIT Decoder software with a new patch from today. The XRIT file manager now provides IR image enhancements for GOES Bands 8 and 13. Here are some examples:

ExaGear x86 Emulator for ARM To be Discontinued

ExaGear is an x86 emulator for ARM computing devices. In the past we posted about ExaGear as together with WINE, it was an affordable solution that allowed Windows SDR apps to run on ARM devices like the Raspberry Pi 3. With ExaGear and WINE we were able to get Windows only SDR programs like Unitrunker, WinSTD C, DSD+, MultiPSK, PC-HFDL, Orbitron and Sondemonitor to run smoothly. In another previous post, DE8MSH was also able to use ExaGear to get Speclab running on his Raspberry Pi 3.

Unfortunately it appears that ExaGear is to be discontinued from February 28 onwards although they note that all previously purchased licences will continue to work. No reason has been given other than noting that it is their business decision. For now the downloads and ability to purchase licences is still active until February 28, so if ExaGear was a product you were interested in, you have just over a week to obtain it.

Es’hail-2 Amateur Transponder Now Active

Es'Hail 2 Coverage
Es'Hail 2 Coverage from Amsat-UK

Es'hail 2 was launched last November and it is the first geostationary satellite to contain an amateur radio transponder. The satellite is positioned at 25.5°E which is over Africa. It's reception footprint covers Africa, Europe, the Middle East, India, eastern Brazil and the west half of Russia/Asia. There are two amateur transponders on the satellite. One is a narrow band linear transponder which uplinks from  2400.050 - 2400.300 MHz and downlinks from 10489.550 - 10489.800 MHz. Another is a wide band digital transponder for amateur digital TV which uplinks from 2401.500 - 2409.500 MHz and downlinks from 10491.000 - 10499.000 MHz.

Although it launched last year it takes several months for the engineers to test and qualify the transponder for use. Over the last few weeks the transponder was intermittently active during the testing, but now since Feb 13 2019 the amateur transponder has finally been fully activated for amateur radio use.

To receive it with an RTL-SDR or most other SDRs an LNB is required to receive the 10 GHz signal and downconvert it into a frequency range that most SDRs support. Typically an Octagon LNB is used, and these are easy to find and cheap as they are often used for satellite TV.

From various reports seen on Twitter, it seems that the signal is strong enough that a satellite dish is not required for receiving - simply pointing the LNB directly at the satellite is enough.

If you can't set up a receiver, there is an OpenWebRX livestream of the Es'hail 2 narrowband channel that has been set up by Zoltan/RFSparkling which is available at sniffing.ddns.net:8073 (note the server can only handle 8 users at a time, so try again later if it's busy). Also as pointed out by KD9IXX on Twitter, there are also several websdr.org servers receiving and streaming Es'hail2 including an Airspy based one run officially by AMSAT-DL.

YouTube Tutorial: Eavesdropping on DECT6.0 Cordless Phones with a HackRF and GR-DECT2

Back in December of last year Corrosive from his YouTube channel SignalsEverywhere showed us a demo video of him receiving unecrypted DECT digital cordless phones with his HackRF.

DECT is an acronym for 'Digital Enhanced Cordless Telecommunications', and is the wireless standard used by modern digital cordless phones as well as some digital baby monitors. In most countries DECT communications take place at 1880 - 1900 MHz, and in the USA at 1920 - 1930 MHz. Some modern cordless phones now use encryption on their DECT signal, but many older models do not, and most baby monitors do not either. However, DECT encryption is known to be weak, and can be broken with some effort.

In his latest video Corrosive shows us how to install GR-DECT2 on Linux, which is the GNU Radio based decoding software required to decode the DECT signal. He then goes on to show how the software can be used and finally provides some optimizations tips.

3D Printed V-Dipole Holder for Our RTL-SDR Blog Multipurpose Dipole Kit

Over on Thingiverse user f16v1per has created a 3D printed bracket that can help with securely holding our multipurpose dipole kit at a 120 degree angle, which is the perfect angle to use when in a V-Dipole configuration. A V-Dipole is simply a dipole antenna spread at 120 degrees, placed horizontal to the ground, and typically oriented in a North-South direction for receiving weather satellites.

Back in 2017, Adam 9A4QV wrote about how a V-Dipole could be used as a very simple yet effective antenna for receiving weather satellites. Since then it has become a popular beginners choice for receiving polar orbiting satellites like NOAA and Meteor M2.
