Digital Readout for Kenwood TS-520S This PCB was designed by Steve KV6O http://www.kv6o.com/wordpress/projects/kenwood-dg5-emulator/

Parts Info:

http://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=03394fdd5d – Mouser parts, includes most of the components.

http://sfe.io/w97558 – SparkFun parts, includes RCA jacks, LCD display, 4″ jumpers for the display, etc.

The LCD is the most expensive part in the build (besides an Arduino), if you have one already the parts are about $20. Less if you have a well stocked parts bin. Arduino’s can be had for less than $10 on eBay, and the LCD display (a 16×2, HD44780 based display – very common) can be had for a few bucks if you look around and can wait on shipping.
