In 2018 the three PIC-based Display and Control Boards were replaced with a single Arduino Mega. The software was ported from C to C++. The Arduino software is available on GitHub at the following link: https://github.com/RodNewHampshire/Express-Receiver-2018-Update
I2C LCD Backs from Adafruit were added to each of the LCDs allowing I2Cbus connectivity to the LCDs.
The VFO and LO Board was replaced with a VFO, LO and BFO Board. Si570s were kept for the LO and VFO, and an Si5351A added for the BFO, replacing the AD9835 DDS on the Product Detector, BFO and Audio Stages Board.
