Re: RBW filters
It would cost some arithmetic, but it shouldn't be hard to run a 8-12 point filter and significantly improve the shape. For low computational cost I like triangular weightings. The multiplies can be

Re: tinySA for RFI hunt?
One of the main problems with Plasma TV's, tends to be the Plasma itself, which is basically an electric arc contained in a gas, and if the screen is of a decent size, it can radiate significantly.

Re: 3D Printed Case for tinySA

OK - here is my take on the "minimal" tinySA case - sized to only accept the tinySA with no accessories (but I think the guitar pick should fit in the space between the sma connectors).? As before, I

Re: 3D Printed Case for tinySA

OK - I will shrink it down to the minimum.? No place for the guitar pick "stylus" either?? I might have a natural place for that between the SMA connectors - we shall see...

Re: 3D Printed Case for tinySA

Correct, no test leads, no antenna, no accessories, except the mounted SMA Savers. Once they are on with the correct momentum I don't want to remove them, but I want to protect the TinySA (NanoVNA) in

Re: 3D Printed Case for tinySA

So just to be clear - are you looking for something that would just hold the tinySA and those attached connector savers?? No place for antenna or connector cables? Also - to respond to Lawrance - if

A common SMA-saver is?SMA5071A1-3GT50G-50 from Amphenol Mounted on the case it will extend 18 mm from the plastic, 19 mm with the yellow plastic cap (as opposed to 6 mm and 7 mm respectively in

Re: 3D Printed Case for tinySA

If you can provide/confirm the lengths of the SMA savers (measured from the edge of the tinySA case, I could probably model something up (not as quick as the last one).? I don't have the nanoVNA, so

Re: 3D Printed Case for tinySA

I would prefer a smaller version that just has room for the TinySA with SMA-savers. A case like this would also work for my NanoVNA. Cables, attenuators, calibrations sets and more converters I keep

Re: tinySA for RFI hunt?
Jim, I feel the pain of noise as well. I have noise sources that are well into my IC-9700 at 1296 here, and I'm out in the countryside by a good distance. One would think the area would be RF quiet
