Blog write up and photos at: Frequency Display for a Kenwood TS-520S HF ham radio PART 1A friend has a Kenwood TS-520S HF (high frequency) ham radio. He does not have the optional DG-5 frequency display and calibrating the dials between bands is not much fun. He gave me some information about the DG-5 and through some review I believe I can make a substitute for the DG-5 using an Arduino, LCD Shield and hand full of chips.He could buy a DG-5 but that would cost more than he paid for the whole rig and it really is not necessary to use the radio, just more convenient.This is part one so watch this video which covers my idea and some pre-testing. All looks good so far and I'm already working on part two.I got the Arduino frequency library from this site: the video I just use the libraries example scketch so I have no code to share in part 1.I also followed some circuit examples shared at these two sites which both built HF frequency counts and where great sources of information to help me on my way to building an Arduino derivative HF frequency counter. My counter is for a single custom application and so doesn't incorporate all the features these other builds include. website to get development software and sample code:http://arduino.cc got my Arduino and LCD shield from Adafruit.com
