/diy/ - Do It Yourself

If you do it the Matlab route it is not hard but then again you don't get to learn what is happening under the hood. Matlab is not optimal in speed, you need assembly code for that.

DSP assembly code is not too hard, it is just different. It is when you understand the algorithms and the DSP instruction set architecture that you can make the very best code.

If you want to apply this you could look into software defined radios (SDR). Many modern radios are SDR at the heart.

Thank you. There's also the schematics of the Frog (2 crystals), a modern direct conversion transceiver called QXC (pic) and more interesting stuff like the antenna series by W8JHD (antennabook.pdf).

Design seems interesting. Curious about the bands, are those fixed when you buy the kit?

Seems the ADC sampling speed is a bit low, perhaps 7kHz, or are there two ADCs?
