AIOC All In One Cable For Ham Radio transceivers including Baofeng, Quansheng and many other makes of portable transceiver.

This upgraded version has the option of supporting Hardware COS on the Tidradio TD-H3

Pack of Three available, see my other eBay items 

V1.3 FIRMWARE PRE-LOADED AND READY FOR USE

This is a kit of all the parts needed to assemble the open-source project  The All In One Cable (AIOC) from Simon Küppers 

It includes:

• AOIC board with all surface mount components and firmware installed
• 3.5mm TRS jack plug
• 2.5mm TRS jack plug

For instructions on enabling the Hardware COS feature see the G1LRO blog

I recommend using the 3D printed soldering jig to ensure good alignment. This is not included but the print files are on the github repository and also on my ebay store.

These units are not assembled but do have the latest (1.3.0) firmware installed as a basic confidence test of the operation of the AOIC processor.

This item is currently in beta testing phase - Be wary! Please read this README on github and familiarize yourself with the item and how to use it.

This adapter incorporates thee functions:

• USB sound card to convert the receive/transmit audio from the transceiver to USB
• USB to serial adapter to allow programming of your transceiver from radio software such as CHIRP
• Full PTT control to allow automatic receive & transmit using either serial port settings (DTR & CTS) or the CM108 standard supported by popular software (including Dire Wolf.)

It is an amazing addition to your portable transceiver 

You can use this for APRS, Packet Radio, Winlink, Programming or any other sound card data mode. 

Compatible with all portable radios that use the Kenwood Style connector (unless your radio has the programming chip built in, then it will only do data modes, not programming).

 If your radio doesn't have the Kenwood connector, you can easily make own custom cable using the solder pads on the board.

Please note this is an experimental and hobby item and is not ruggedized for commercial use. The exposed components are vulnerable to damage through mishandling.

The firmware and operation of this unit is dependent entirely on the open-source project and subject to those limitations.

For instructions on how to use this this AIOC, see the Github information

Please note: there is a minor issue with the AOIC when used with radios with attached antennas, where the transmit power can cause the AOIC to lock up. This issue does not seem to occur when used with an antenna connected via coax cable.

The CM108 PTT takes some configuration to work in DireWolf, and is not supported on the Windows version. The serial port PTT is straightforward to set up with a config line such as:
PTT /dev/ttyACM0 -RTS DTR
