Using an Arduino to Upgrade a 1970s Ham Radio

Al Williams WD5GNR writes on Hackaday about upgrading the vintage Icom IC-245 with an Arduino

Old radios didn’t have much in the way of smarts. But as digital synthesis became more common, radios often had as much digital electronics in them as RF circuits. The problem is that digital electronics get better and better every year, so what looks like high-tech one year is quaint the next. [IMSAI Guy] had an Icom IC-245 and decided to replace the digital electronics inside with — among other things — an Arduino.
