Hello IACooper, Thanks for the valuable information. Would like to know more about that experience with the heyphone using the pc. The sm1000 seems to replace the pc for the codec so probably is possible to implement it on a cave radio also. Will try to reach Rob, maybe I could collaborate with him ...

Hello David,

Thanks for the reply.
The Nicola 3 is not a real digital radio but a mix of an analog with some digital to generate the frequency for transmit.
My idea is to creat a radio to operate like digital televison.
The audio received signal is much more clean.

How about a real digital radio? Maybe it could eliminate the static noise always present on this 87kHz analog models. I do agree with the minimum commands the better but also the simple the design it could be easier for others to replicate. Would like to be involved in the next generation of radios....
