How send and receive data trought cable

[zapewne]

Hello.

I have a usb<->audio *2 io to quansheng. How I can send and receive data trought it? I need sending and receive digital data trought radio (no setup, only send data to other radio trought radio wave).

I need simplest way to send and receive data.

You can use 'UZ7HO Sound Modem' as ADC/DAC and 'dg1faz Paxon' as gateway. But it works in analog mode, no usb i/o. You must use on-board sound card or usb sound card. UV-K5 have build-in BK4819 FSK modem, but question is to accessible it from outdoor software.

UKk5 have to read the data on the multi-radio has its own digital converter. It can read and send data much better than a sound card. Besides, you require a whole computer. Why . When you can use a radio to do it using less power and be more mobile.

If you could read and send data directly using firmware like the T9 extension, but from a USB device, you could control it with an arduino or router or other device like a cell phone.

This is a very good question. But requiring a change in firmweare.

The question is, does the circuit design provide direct access to the DAC for usage it as modem, what
modulation will be and which speed?

This is the subject of the question. It seems that if the firmware allows such transmission then the speed will be variable from 600-2400 baud.
And most importantly it will be easy to write a client of any network.
There could also be interoperability between the world of ham radio and those without a license.

You can ask Nunu (@kamilsss655) about their Mesh network.
