I am no coder. I am more a problem solver.
We know that the more we go into time the less CM108 or the like chips are going to be available.
We have problem with hickups on the usb driven interface and while SBC are getting more powerfull we still suffer from small cuts in audio.
The production of the voter boards are stopped and making the original one is not that as easy as many of the component are going into obsolescence.
I was thinking about this and I started to think of what type of device could do a nice audio interface that could also have enough power to do DSP for squelch and tone decoding and have i/o that can be driven in real time to control the repeaters.
And I got that silly idea that they just did it with the MMDVM STM32 digital controler.
They added voice to all the stm32 based MMDVM.
Those are powerfull enough to decode digital voice. and they encode them very well. Now if we could use the same chips but not with all the digital stuff. Just the analog with the possibility to do do dsp like on usbradio ( but on the chip, not on asterisk) and at the same time and not use a USB method of transfert,
but use IP and maybe use the USRP protocole as a base of communication or even the voter IP method.
Anyone have been thinking about this?
