Re: [Freetel-codec2] First pass at a schematic for a small, cheap radio that runs Codec2

Good to see some work in this area Bruce, good luck with your project. Suggest you use the LPCNet codec, it can run on high end phones, and will provide a large increment on speech quality over anything in the commercial or Ham worlds. - David On 24/05/19 05:01, Bruce Perens via Freetel-codec2

I really like the idea of having base systems tell the mobiles how far off their frequency is. The chip does incoming frequency determination. Thanks Bruce On Thu, May 23, 2019 at 3:34 PM Steve wrote: > Probably fast forwarding ahead, but I was thinking since GPSDO are > pretty cheap

Probably fast forwarding ahead, but I was thinking since GPSDO are pretty cheap (leo bodnar) with programmable output frequencies into an SMA, that it would be an excellent input option along with the XTAL or TCXO input to the AX5043. Just a first pass reading the files, but I like it! Is there

Please see https://perens.com/2019/05/23/ht-of-the-future-new-design/ I don't know anything about hardware design and did this one by myself. So, please point out mistakes, etc. Thanks Bruce -- Bruce Perens - Partner, OSS.Capital. ___
