Re: My tinySA Ultra Signal level Critical #ultra

 

Are you running the latest firmware? The version info is difficult to read.
The last picture seems to suggest the LNA is not amplifying and this will be detected with the latest FW

After I replace RF switch all look ok I can LevelCal not Critical level .



But I SELF TEST? ?test 13 not pass.
Re: Linux Mint USB #tinysa

 

I am able to use both my tinySA and my tinySA Ultra with Linux Mint 20.3 Cinnamon and tinySA-saver 0.2.2.? Are you using the latest version of tinySA-saver from github?



I have heard some have had problems connecting with USB3, but USB2 works OK.? If you have problems with one, you might try the other.? Try hitting the rescan button if saver doesn't see your tinySA.

I hadn't used tinySA-saver in some time and just installed the latest version recently when I got the Ultra.? I used

git clone https://github.com/erikkaashoek/tinySA-saver

in a terminal to download, then used cd to switch to the newly created folder and followed the directions for Ubuntu in the README.MD file, except that I just used python3 where the instructions specified python3.7 since Mint 20.3 is using python 3.8.10 and will use that automatically when given the command python3.? Python3 and pip were already installed, so I ignored that part of the instructions to install those.

Larry,
The topic is tuning a duplexer:

Searching for your post is made very difficult by group.io's poorly implemented search feature and the fact that is not a URL link but a mailto:

Hi Folks,

Here are photos of the ULTRA case as provided by spiff72 at a great price.

I am very pleased with the results and will buy another!

Absolutely.? I no longer use SWR curver.? The Smith Chart tells you everything you need to know and then some.? SWR curves are lacking in the complex portion of impedances and circuits.? The reflection in vector form is also useful, but the Smith Chart covers all the bases.

Dave,

there is an exception: one of the Advantest (former Takeda Riken) spectrum analysers with tracking generator (4167?) had the option of phase display and in addtiion with an external bridge? a smith display was possible

Did I imagine this, as I now see it as a .pdf file ?

I'm sure it previously opened in Visio when I tried it, unless I somehow picked the wrong one in the files section.

Apologies if that was the case.

David,

Many thanks for doing this. The Wiki is clearly written, but being able to see a complete wiring diagram has really helped understand how everything relates. The notes are the cherry on top!
