Locked Re: TinySA introduction video


 

Larry,

I agree with some of your comments. But I can tell you for portable use the 4" is much better. Also I take some offense to the comments on hams. I have been licensed since the 1970's and spent all of my career in electrical engineering designing all types of electronic devices and T&M equipment. I can assure you that I know what a spectrum analyzer is and does, just as sure as there are many hams that know the same as they started their engineering careers due to their interest in ham radio.

I personally know dozens of hams that are excellent RF engineers and know their way around an RF lab so for you to make such a careless general statement is harmful to the fraternity.

Sure there are "lids" that are hams just as there are in general society. So instead of lambasting them, how about taking on the task of educating them so they will understand how to use their TinySA?

If Erik is able to keep up with the demand perhaps the volume of sales that you predict will allow him to further improvements and/or new future products.

In the end we will all benefit.

Sincerely,
?

Erik-
Kudos. I also am anticipating rollout as a spectrum analyzer is exactly what I need. I've tried RTL-SDR dongles and it doesn't give you a "big picture". Especially when we are going after interference that we find "walking up and down" the band. Same with CABLE leakage. and here in the US, that's a problem.

I also think you're conservative approach to the 2.8" vs 4" version is appropriate. I did buy a 2.8 NanoVNA then "had to have" a 4. I have used my 2.8" 10 times that of the 4".?? Because on the bench the 2.8" is attached 100% of the time now to a PC..? Being able to capture, view, store and print graphs plus using my mouse that I'm accustomed to after 20+ years of steering one. I'm happy.?? Both the 2.8 and 4.0 are hard to read in direct sunlight. cardboard boxes help. Who does not have a computer, tablet or smart phone for a bigger display these days?

Finally, although selfish, I would hope and I'm sure all on here would agree, that you allow your followers 1st crack at the release production run, as the second something new comes out, the pig herd (hams) will run out and want one and they can't even spell spectrum or analyzer. In the USA we have a comment regarding them, "more money than brains"? In any case they will deplete units on the shelf, then bombard? the group with stupid questions. The downside to your journey to fame and fortune.
