[Elecraft] Question about K3 firmware

[w2bvh at comcast.net]

Just out of curiosity, does the K3 firmware run inder a rtos? And if so, it it home grown or a commercial product?
(I assum the DSP is programmed down to the silicon).

The K3 looks like a truly outstanding product thats user oriented in terms of features and interface. Congrats!

Now I've got to start saving up for one.
