Might be a better option than Pi3 for SDR and digital ham applications.

Finally, got my my RA 818-v to playwith. Bought it from ebay few months ago. Combine it with atmega328 as its controller. i designed the pcb with 100 % trough hole components, except of course the DRA itself. Project still on going, with hardest part for me, making panel cutout for the lcd display.

I had been thinking about buying a Spectrum Analyzer with Tracking Generator but they run in $1500 range. I found two alternative PC based solutions

1. PC Based Vector Network Analyzers: miniVNA PRO

2. The DG8SAQ VNWA 3 and VNWA 3E Low Cost Vector 1.3 GHz Network Analyzer

My application for HF applications and antenna work. I am not into GHz type projects.


If any of you have either of the devices please share your thoughts. I am reading the manuals and looking at software. They are both in my price range so that really isn't a factor.
