[Elecraft] KDSP2 option's DSP firmware is open source

[Matt VK2RQ]

Even if you find the development kit, the memory chips in the latest K2DSP boards are not in sockets, but are soldered directly to the board. So, it would be difficult to upgrade the firmware on the K2DSP. Also, the firmware for the user interface is not open source, which limits the scope of adding features.

These days, if you want to experiment with DSP algorithms, it is probably more convenient to do prototyping on a general-purpose PC with sound card.
