Build Your Own 1.5GHz Satcom-ACARS (INMARSAT) Receiving System with the AR5700D Receiver!
Unlock the Full Potential of Your AR5700D

The AR5700D receiver, capable of receiving signals up to 3.7GHz, opens a gateway to explore signals and data beyond the usual spectrum. For those curious about what lies above 1GHz, here's a practical and exciting project: decoding CLASSIC AERO standard signals in the 1.5GHz L-band. These signals, known as Satcom-ACARS, are transmitted by INMARSAT satellites to aircraft, especially when they are out of VHF ACARS range.
At AOR headquarters, we created a simple yet effective setup to receive and decode these signals. While not flawless, the system serves as a "proof of concept", combining learning and fun with real-world applications.

Home-made L-band patch antenna mounted on a camera tripod. The antenna is made using a 0.5mm thick copper sheet as you can easily find at home centers.

The AR5700D receiver is controlled by SDR# (right side of PC monitor), which sends the audio to the JAERO decoding software (left side of PC monitor) via virtual audio cable software.

JAERO (SU tab) currently decoding the raw data of the AERO signal.

Getting Started: Tools and Setup
Begin your journey with guidance from the JAERO software page,(https://jontio.zapto.org/) which offers an excellent conceptual overview. Here's what you'll need:
Hardware:
- Receiver: AR5700D (alternatively AR2300IQ, AR5001D with IQ5001, or AR6000 with IQ5001 options)
- Antenna: DIY L-band patch antenna (as detailed in the TECH MINDS YouTube tutorial) https://www.youtube.com/watch?v=luVPpzopmrY
- Amplifier: Low-noise amplifier (LNA), ideally L-band-specific for optimal signal-to-noise ratio. We used the AOR LN4000 100MHz-3GHz wide-band amplifier because that’s we had available for the test, but it is not ideal. You should rather use a specific low-noise amplifier including a filter for the L-band (1.5GHz) for best signal to noise ratio (S/N).
- Coaxial Cable: High-quality UHF coaxial cable. We used Airspy’s YOULOOP 2m long transmission line (blue cable), which is rated up to 18GHz.
- Computer: A standard Windows PC
Software:
- SDR# by Airspy: Free receiver control software https://airspy.com/download
- VB-CABLE: Free virtual audio cable software https://vb-audio.com/Cable/
- JAERO by Jonti Olds: Free decoding software (Visit site) https://jontio.zapto.org/
-----
Why Choose the AR5700D Receiver?
Unlike cheaper SDR dongles, the AR5700D offers:
- Low Noise Floor: Ideal for detecting weak satellite signals
- Frequency Accuracy: Ensures precise signal reception
- Exceptional Image Suppression: Reduces ghost signals and harmonics
- High Carrier-to-Noise Ratio (C/N): Enhances signal clarity
You can see that the noise floor of AR5700D is about 50 units lower on the vertical dBFS scale of SDR#, compared to with the RTL-SDR.COM dongle. It does matter a great deal for weak satellite signals.

How It Works: Our Setup in Action
1. Antenna: A home-made L-band patch antenna mounted on a camera tripod, built using a 0.5mm thick copper sheet.
2. Signal Processing: The AR5700D receiver connects to SDR#, which sends audio to JAERO via VB-CABLE for decoding.
3. Decoding: JAERO's interface translates raw AERO signal data into readable Satcom-ACARS messages.
-----
Additional Tips for non-I/Q Receivers
You can actually decode Satcom-ACARS by using the standard AR2300, AR5001D and AR6000 receivers not fitted with the IQ5001 option! Simply connect the receiver’s LINE-OUT to your PC’s LINE-IN or use a USB audio interface if required.
A simple 3.5mm stereo jack cable connects the receiver to the PC. Here we had to use a USB audio interface because our PC had only MIC-IN which is easily overloaded.

--------
Tips for the Best User Experience:
1) Handling the "Server is busy" Message
If you encounter a "Server is busy" pop-up when starting the remote connection with SDR#, don’t worry! Simply wait a few seconds and try reconnecting. This delay happens because the boot-up sequence of our receivers takes a few moments to complete.
2) Fixing Choppy Audio
If you experience chopped audio during playback, you can resolve it by adjusting the buffer settings:
Open the spyserver.config file.
Increase the values of input_buffer_size_ms and output_buffer_size_ms to 200.
Save the file and restart spyserver.exe. Problem solved!

Au-delà des échanges traditionnels, il englobe une multitude d'activités techniques et expérimentales. Parmi les aspects essentiels du radio amateurisme figure l'écoute des bandes radio. Les radioamateurs chevronnés investissent beaucoup de temps dans l'écoute passive des communications, à la recherche de signaux faibles ou de transmissions rares. Cela leur permet non seulement d'améliorer leur compréhension de la propagation des ondes, mais aussi de perfectionner leurs compétences en identification des signaux.
En parallèle, les radioamateurs procèdent à des tests de performance sur leurs équipements, mesurant divers paramètres tels que l'impédance des antennes, la puissance d'émission, et la qualité des signaux. Ces activités sont cruciales pour assurer des transmissions de haute qualité et minimiser les interférences.

Photo 2: Technologie et expertise: Le banc de test radio entièrement équipé pour l'expérimentation et la maintenance des équipements, soutenu par PROSIC et AOR Ltd. Des solutions simples et efficaces, comme celle-ci, sont essentielles pour garantir une utilisation optimale et durable des équipements radio.
Le dépannage, quant à lui, constitue une compétence clé pour les radioamateurs. Savoir diagnostiquer et réparer des équipements défaillants est essentiel pour garantir la continuité des opérations.
Cependant, avant de pouvoir pleinement s'adonner à leur passion, les radioamateurs doivent suivre une formation technique approfondie.
Toutes ces activités requièrent un espace dédié où ils peuvent se consacrer pleinement à ce hobby à la pointe de la technologie.

Exceptional Performance of the AR5700D Receiver in Challenging Conditions (part 2):
The Secret Behind its Exceptionally Low Noise Floor
The AR5700D communications receiver sets a benchmark in the SDR market with its exceptionally low noise floor, primarily due to the LTC2205-14 ADC chip. This 14-bit, 65Msps ADC minimizes noise through its high resolution and fast sampling, essential for preserving signal integrity.
Key features contributing to its performance include:

High SNR and SFDR: With a signal-to-noise ratio of 78.3dB and a spurious-free dynamic range of 98dB, the ADC excels in distinguishing signal from noise, crucial in varied signal environments. (Dither=off SFDR=103dBFS @15MHz, Dither=on SFDR=113dBFS @15MHz)
Dithering and Data Output Randomizer: These options help in reducing quantization noise, enhancing the accuracy of digital outputs.
Ultralow Jitter and Wide Bandwidth: The ADC’s 90fsRMS jitter and 700MHz bandwidth ensure precise sampling and handling of high-frequency signals without loss of quality.

The following graph showcases how well the ADC handles signal conversion at a fundamental frequency of 14.9MHz, with dithering applied, reflecting its pure performance. It clearly depicts the signal-to-noise ratio and the absence of spurious frequencies, which are critical for illustrating the low noise characteristics of the ADC.
LTC2205-14: 32K Point FFT, fin1=14.9MHZ, -7dBFS, fin2=20.1MHz, -7dBFS, PGA=0, DITH=1

LTC2205-14: 32K Point FFT, fin1=14.9MHZ, -7dBFS, fin2=20.1MHz, -7dBFS, PGA=0, DITH=1

The integration of these advanced features makes the AR5700D highly effective and reliable for applications demanding high sensitivity and minimal noise interference.

AR5700D Multi-Simultaneous Receive Capability with SDR# Software
We are excited to announce the latest development for our AR5700D wideband communication receiver. As demonstrated below, users can now leverage the powerful capabilities of the SDR# software to enable multi-simultaneous receive functions in their AR5700D receiver.
AR5700D_multi-receive_SDR#

This advancement allows for monitoring multiple frequencies concurrently within the maximum bandwidth of the I/Q stream, which is 0.9 MHz wide. This significantly enhances the versatility of the AR5700D. The SDR# software from our friends at Airspy, integrates seamlessly with the AR5700D to provide a comprehensive and flexible monitoring solution.
For a demonstration, please watch (and listen to!) the video below. It showcases the SDR# software actively monitoring multiple AIRBAND frequencies of Tokyo control, tower, approach, and departure. The video also highlights how simple it is to open a new receiver session by just clicking the "plus" icon at the top left of SDR#. The actual number of sessions which can be opened is actually only limited by your PC's processing power.
AR5700D_multi-receive_SDR#

We believe this enhancement will greatly benefit our users by providing more flexibility and efficiency in their monitoring activities. Stay tuned for more demonstrations of what can be achieved by the combination of AR5700D and SDR#.
You can download the latest version of SDR# from the official AIRSPY website at https://airspy.com/download/
By the way, the same capabilities also apply to receivers AR2300IQ, AR5001D with IQ5001 option, and AR6000 with IQ5001 option, so why don't you try it out?

We are excited to share a glimpse of the new SDR# version 1920 in action, showcasing its seamless integration with AOR I/Q receivers.
The screenshots below demonstrate the user-friendly interface and advanced functionality.

HAMEXPO 21 OCTOBRE 2023 LE MANS - PARC DES EXPOSITIONS Le salon des RADIOAMATEURS

2023.09.12

On September 10, the “Journée des Associations” took place in Provins, spearheaded by the French radio-club F6KOP.
Attendees witnessed captivating live TX/RX tests utilizing the QO-100 Es'hail 2 satellite. Beyond its primary functions, such as direct TV broadcasting and distribution of governmental and commercial content, Es'hail 2 offers a linear transponder for amateur radio services. This encompasses low-power narrow bandwidth voice, Morse, and digital communications.
Fred from PROSIC, our esteemed French distributor and a long-time supporter of the radio-club, showcased the AR-DV10 receiver. With remarkable ease, he received and decoded the amateur radio downlink from Es'hail 2 using a off the shelf ASTRA-type satellite dish.

While the dish is receiving the downlink frequencies around 10.489GHz, AR-DV10 is tuning to the downconverted frequencies output by the LNB, at around 739 MHz. In line between the antenna and the receiver are a Bias-Tee to power the LNB, and an attenuator for optimal signal level.

Kudos to the AOR distributor in France, PROSIC, for his honorable initiatives for the blind and visually impaired radio amateurs. Last April, members of PROSIC, UNARAF (National Union of the Blind Radio-Amateurs of France) and F6KOP (French radio club) have been honored guests of an event organised in Abidjan, capital of the Ivory Coast, for the benefits of INIPA the National Ivorian Institute for the Advancement of the Blind.
PROSIC and UNARAF have already cooperated in the past for the creation of DV1-UNARAF, a control software for the AR-DV1 receiver, dedicated to the blind and visually impaired.
Below are some photos of that INIPA event in Abidjan:
