Product Usage Instructions

Control Principle

The R1 controller facilitates radio network links by detecting audio input from the radio PTT and transmitting it over the network. It also receives audio from the network and forwards it to the radio.

Controller Applications

Using the R1 controller, you can set up radio links or relay links to extend the range of radio transceivers or repeaters, enabling global radio links.

Software Support

The product supports various software applications including AllstarLinkECHOLINK, ZELLO, SSTV, psk31, SKYPE, QT, YY, and others for voice chat, data transfer, and intercom purposes.

External Radio Connection

The R1 controller can be connected to radios using different converter boards based on the radio station interface. Ensure correct switch positions for different radio types.

AllStarLink Function

Make sure to toggle the ASL switch based on the usage scenario.
When ASL is enabled, the controller detects COS/CTCSS and controls PTT for AllStarLink connections.

DIN 6 Interface

Use the appropriate cable and conversion boards to connect R1 to YAESU/Kenwood/ICOM radios or Motorola/MotoTRBO radios through the DIN 6 interface.

USB Connectivity

The R1 controller can be connected to a PC or Raspberry Pi using USB for audio interface, keyboard detection, and serial port communication based on the software being used.

Frequently Asked Questions

Q: Can I use the R1 controller with radios other than YAESU/ICOM/KENWOOD or Motorola?

A: Yes, you can use the R1 controller with radios having different interfaces by using the appropriate converter boards and ensuring correct switch positions.

Q: How do I know if the AllStarLink function is enabled?

A: The ASL switch position determines if AllStarLink is enabled.
Make sure the switch is in the correct position based on your connection requirements.

Product features are as below

Built-in USB sound card chip, with high-quality audio input and output.
Built-in USB serial chip. E.g. launch control using RTS, receive control using DSR. （ECHOLINK User）
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）
The control software forwards the input voice of the microphone with the detection of the SQL radio signal from the USB chip（ZELLO User）
The USB-Radio Interface is compatible with AllstarLink.
- GPIO Detect COS and CTCSS input. GPIO outputs and controls the PTT (ASL soundcard function).
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.
R1 introduces the of electric conductor or circuit (inductance) to isolate Power/RF interference and high-frequency radiation.
Full Metal case shields all other interference.
Industrial design with standard production process.
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, therefor global radio link is achieved.

The software that this product supports is.

AllstarLink、ECHOLINK, ZELLO, SSTV, psk31, SKYPE, QT, YY, and other chat intercom and data transfer software.
Notes: There are some software are that do not support USB and control detection, thus at this time, while on the computer microphone input, we can use the software VOX function。

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:

Note: 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: 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 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 (select 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.
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.
