Peter:
Here is a sneak preview of the CB40v3 which is off to the fabricators to get some prototypes made. It has TX detect so will allow split channel/frequency, additional memory channels, support for color RGB OLED's, 7 Segment LED display support from 2-6 digits and a host of other things. The Atmel 328P in the v1/v2 has been replaced by the Atmel 1284P giving me 4 times memory to play with and add features. It is exactly the same size as the v2.
