I am looking to replace my bricked (or as Larry Rothman put it, burnt) original Huygen nanoVNA-H. It appears I have a choice: original Huygen nanoVNA-H at a pretty good price or an original Huygen nanoVNA-H4 at a higher price. Now, the questions are is software development for the -H or is all the development being directed to the -H4 and other competing(?) devices? The difference in screen sizes doesn't really bother or impress me but continued development does. I do note that the -H continues to be sold at a pretty good rate.
Next question: I looked at the site selling the original -H and on one of the displays they show what appears to be a smart phone connected to the -H giving a much larger display. Has anyone tried this? If so, is there an app available for it. If so, I've missed it.
