Last week was the second week with Paul m0zmb  showing  some of his experiments using the Arduino open source electronics platform.  We looked at a full colour LCD display from Tony G0WMB and my (John m0hfh) experiments to link the Arduino and a AD9850 dds module to give a variable sine wave output with a variable frequency from a few kilohertz to 30mhz; a very useful VFO. We stayed later than we should  to test the output using the club radio on 3.5mhz and 7.2mhz  and the circuit achieved our first goal, and a signal was detected at approximatly 4m distance using very crude wire antennas.
