Avrtx R1-2020 Radio-Network link Controller

R1-2020 User Manual ver 2.2

The R1-2020 is a Radio-Network link Controller that can be used to connect various types of radios to the internet. The product features include GPIO Detect COS and CTCSS input, GPIO outputs to control the PTT (ASL soundcard function), optocouplers and isolating the transformer to prevent Power/RF interference noise, electric conductor or circuit (inductance) to isolate Power/RF interference and high-frequency radiation, full metal case to shield all other interference, and LED status indicators.

Control Principle

The R1-2020 uses Internet voice chat software to detect audio input from the radio PTT and transmit the audio over the network. On the other end, the controller detects the SQL signal through the USB control of the network and forwards the audio to the radio. This allows for radio links or relay links to be set up and extends the range of radio transceivers or repeaters.

Controller Applications

The R1-2020 supports various chat intercom and data transfer software such as AllstarLinkECHOLINK, ZELLO, SSTV, psk31, SKYPE, QT, YY, and others. Note that some software may not support USB and control detection, in which case the VOX function or keyboard conversion software can be used.

Product Usage Instructions

When using the R1-2020, follow these instructions:

1. Connect the R1-2020 to your radio using the appropriate cable and conversion board (if necessary).
2. If using AllStarLink to connect with Raspberry Pi, set the switch position to ASL ON. Otherwise, set it to ASL OFF
3. Use the switch position to select the appropriate radio type (YAESU, Kenwood, ICOM, or Motorola).
4. Use the GPIO inputs and outputs to detect COS and CTCSS input and control the PTT (ASL soundcard function).
5. Use the LED status indicators to determine if the R1-2020 is controlling an external radio or if the external radio is receiving a signal.

For more information on specific connections and settings, refer to the Motherboard function diagram and R1 external screen function description with laser engraving in the user manual

Product features are as below

1.  Built-in USB sound card chip, with high-quality audio input and output.
2.  Built-in USB serial chip. E.g. launch control using RTS, receive control using DSR. （ECHOLINK User）
3.  The built-in audio detection chip controls the radio’s PTT button and outputs the sound to the speakers by the radio-compute controller. （ZELLO User）
4.  The control software forwards the input voice of the microphone with the detection of the SQL radio signal from the USB chip（ZELLO User）
5.  The USB-Radio Interface is compatible with AllstarLink. GPIO Detect COS and CTCSS input. GPIO outputs and control the PTT (ASL soundcard function).
6.  The user’s computer will not get Power/RF interference noise from the power supply from the radio because the R1 has the optocouplers and the isolating transformer.
7.  R1 introduces the of electric conductor or circuit (inductance) to isolate Power/RF interference and high-frequency radiation.
8.  Full Metal case shields all other interference.
9.  Industrial design with the standard production process.
10.  LED status indicators.

Control Principle
In general, the Internet voice chat software, with the help of an output audio controller detects audio input from the radio PTT, hence the audio will transmit over. On the other end, once the radio receives the audio, the controller detects the SQL signal through the USB control network, and the voice chat software will forward the audio to the radio. In this way, it will be on the radio-linked network.

Controller applications
By getting the radio link to the network, you can set up radio links or relay links and extend the range radio transceiver or repeater, therefore global radio link is achieved.

The software that this product supports are
AllstarLink、ECHOLINK, ZELLO, SSTV, psk31, SKYPE, QT, YY, and other chat intercom and data transfer software.
Notes : There is some software that does not support USB and control detection, thus at this time, while on the computer microphone input, we can use the software VOX function, or use the keyboard conversion software to trigger them.

The following is the picture of R1 connected to FTM-400: ( R 1 Switch position: Y/ K/ I )

YAESU FTM-400 menu “DATA” setting reference

The data transmission of the TNC port of FTM-400 is enabled by default. It is disabled by the “SQL” signal level control triggered by panels “A” and “B” receive frequencies. Therefore, the reception frequency SQL level for panels “A” and “B” should be set to favor “High Threshold”. If the SQL level is set too low, receiving SQL is opened due to radiation interference, which may cause port data transmission to be disabled.

Note 5
Regarding on this R1 appliance box, please be informed that when PC is restarted, it will become abnormal. Please power off/turn off the radio power supply first, then only restart the PC. The reason for the above problem is related to the driving control principle of the R1 and PC. There is no solution to this problem yet. For the extra info, if the R1 control encounters abnormality after the PC is turned off, please set “PC shutdown = USB no power supply” in the PC BIOS.

MMSTV Set reference

Select RX MODE: AUTO

Select: USB serial COM number, Select Exclusive Lock and RTS While Scan

Below is the connection to use in ZeLLO:-
Important Note: Since the new version of ZELLO does not support the middle mouse button mode, you can use the “VOX” mode. Or use mouse-to-keyboard software, the software name is “MouseChange”. Convert the “middle mouse button” to the keyboard value “F7”, minimize the window, and run it. Program MouseChange download website: avrtx.cn.

The “set reference” for ZeLLO

1. set the audio on both input and output to USB PnP Sound Device (windows the operating system already has the integrated driver) Important function microphone settings: System audio management interface, do not select the microphone to enhance or AGC, if you select the option, the audio of the other party will be very loud and noisy。
2. Select ZeLLO detection as “VOX Enabled
3. Set Push to talk on ZeLLO to “Middle Mouse Button”

Note: The new version of ZELLO does not support the middle mouse button mode, you need to run “MouseChange”. Convert the “middle mouse button” to the keyboard value “F7”. The window is minimized to run. At this time, R1 internal detection will be converted to “F” 7 to trigger ZELLO forwarding. Program MouseChange download website: avrtx.cn

Using the same settings, you can also control other keyboard trigger software, for example: ESChat…

AllstarLink Connect to use

Allstarlink settings and Raspberry Pi system mirror download URL: https://allstarlink.org/ https://hamvoip.org/ image download: https://hamvoip.org/#download R1 hardware-related settings of Allstar link

just follow the below setting like mine and make sure you have the toggle here:

Note: For help with connecting Allstarlink to R1, please contact 9W2LWK, email: 9w2lwk@gmail.com

Connection to use in YY: ( YY is only available in the Chinese Simplified version)

On the YY channel, select both the microphone input and speaker output to “USB PnP Sound Device” on the system audio management interface, please do not select microphone enhancement or AGC, if you select the option, the audio of the other party will be very loud and noisy

If you want to set the external radio to receive the audio sent through the network from each other, choose to press the mouse to speak: the middle button (selected the green point, and click the middle mouse button).

External radio transmission is the internal default control, it does not need to be set.
Tip: The middle mouse button control function should be reserved for YY software. In order to avoid mis-forwarding network communications, other software can not overlap/reuse/override the middle mouse button. The last two suggestions are to disable the voice prompt function. This is to avoid miss triggers in communication.
