Re: Level Correction
#ultra
Whenever I want to sniff with the whip antenna I use a preamp or active probe in front of my tinySA.

Touching any metal/conducting object with the telescopic antenna can destroy the LNA
Having a transmitting antenna close (< some meters depending on the output power) to the tinySA can quickly destroy the LNA when active -- For more info on the tinySA go to https://tinysa.org/wiki/ |
Re: Level Correction

I was wrong to think that the problem was software only. I will try to get an IC for the LNA, but I wonder how a device that is connected only to the telescopic antenna without connecting it to any other device can fail so quickly. What could have caused this failure, what should I pay attention to when using it again.

Thank you for giving me your time. |
Re: Level Correction

The video you recorded clearly show the LNA is not working and calibration is failing.
clearconfig will set all default values. No need to do any other level settings. Just a calibration is sufficient. WIth a broken LNA there is no setting you can change to make either the selftest or the calibration succeed. -- For more info on the tinySA go to https://tinysa.org/wiki/ |
Re: QtTinySA
#software
The major change from v0.8.0 onwards was that I use a SQLite database to store all the settings.? For running the Python native version, you may need to add the Qt5 SQLite 3 database driver (libqt5sql5-sqlite) and "Python3 bindings for QT5's SQL Module" from your repository if you don't have them already.? That wouldn't affect the executables though.
My friend Clive is going to see if he can replicate your issue and make any further suggestions. Ian |
Re: Level Correction

Mr. Kaashoek, I also watched your video on YouTube, but the reset I did with that setting turned on does not change anything and gives errors in other tests. Likewise, different tests give error when level input and level output values are changed. Are there default values for input and output values, can I try them.

You have blown the LNA?
see wiki FAQ: "The LNA is not working. Where can I find a new LNA?" -- For more info on the tinySA go to https://tinysa.org/wiki/ |
Re: Level Correction
#ultra
Thank you for your answer. I tried this process many times, but nothing changes.

Do?CONFIG/MORE/CLEAR CONFIG 1234 and recalibrate

Level Correction
#ultra
Greetings,
I am an Ultra user, I noticed that some of the calls I hear on my handheld radio are very very faint on the ultra screen, while I was looking for how to see these weak signals more clearly with the settings, I changed the INPUT LEVEL, OUTPUT LEVEL in CONFIG > MORE > LEVEL CORRECTION. After breaking this setting, no matter what value I enter, test 10 and test 14 give errors with self test. Although I did everything I read on Tinysa group, I could not fix the problem (Calibrate 100kHz to 5 GHz, 30 MHz calibration, clear config, manual adjustment of attenuator value ...). I don't have a second calibration device, are there default values to correct test 10, 14, or do I have to send it to a professional calibration center. (I don't use the device to read exact values, I use it to monitor spectrum traffic, how can I reconfigure it to show weak signals on the display). |
Re: Turn off display
I also wondering about turning off the display, but for another reason - to reduce the CPU load and to reduce the scan time. It seems to me that command "pause" do this, but screen still refreshes with static picture. Is it DMA provides refreshing?
By the way, Erik. May be you have planned to release OEM hardware version for embedding? Without display, plastic case and so on? Best regards? Lev |

Re: Self test
¿ªÔÆÌåÓýChances are excellent it is a clone, once you updated the SW the test failed.? This has been reported for clones. ? Tom ? Sent from for Windows ? From: Menon
