I’ll be quiet for a while…

16 Jan

I’ll be out of town for a couple weeks and will continue where I left off (crystals & filters) when I return.

I also want to begin  discussion of a related project I did long ago and now want to resurrect: A USB-based HF Scalar Network Analyzer (sweep set) for analyzing filters and other frequency dependent circuits. All the hardware and software has been working and available to reproduce for 10 years now. Cost to build should be in the $25 range. I think I’m finally ready to develop a PCB for it and share.

Stay tuned…
