Here’s a quick video of my DG5 emulator prototype buttoned up in a project box.
Still waiting on my PCB’s to arrive on the slow boat from China. I already have changes to make – the first version PCB has the 3 RCA jacks for the 3 signals from the TS-520S on the opposite side from the Arduno’s USB – not exactly the best for mounting in a box. And I also have added the display since I sent in the design, so I’ll have to add that in as well. The “shield” is getting a bit tight with the DIP IC’s and new requirements, I might either go to SMD devices (for the IC’s at least) or just make the shield bigger that an Arduino. This might actually be an advantage, as a bigger shield would allow me to slide it in a Hammond type aluminum extrusion chassis, with the Arduino plugging in on top, upside down.
Got myself one of the AS9850 DDS modules that are available on eBay for around $10. Looking at making an external VFO for the TS-520 with one of these, so a bigger box might be a good idea.
