The amazingly flexible and useful LimeSDR is now rigged up with sliders and rotary pots, a TFT screen and bolt on Arduino Due, hiding underneath the green custom made PCB.

The Arduino communicates via the SPI bus through the FPGA using a special file to re-program the FPGA and enables the Lime to be turned from being a 4G repeater into a frequency hopping/sweeping signal generator within literally 5 seconds. I think I can even put 12 LED indicators on it which might look cool?

I need a signal generator to test my homegrown transceivers on band 13 which is what Verizon uses in more remote areas in the USA.
