Re: New FW release: Added Measure functions

 

Just Updated!? Looks good!

TinySA bug reporting process? #tinysa #bug_report

 

Is there a repository of software/firmware defects and the current status? ?


A link on TinySA.org would be useful. ?Maybe there but I can not find the URL.

Go Erik!? In another few days, the tinySA will be able to control a spacecraft's flight to Mars in order to establish a new human colony there! ;-)

Re: HowTo for building the tinySA firmware under linux (ubuntu lts 20.04) #firmware-build

 

I guess I wasn't clear.?? I found the problem, and fixed it, about a week ago. I told Erik about it, but as you can imagine, he's a pretty busy boy these days, so hasn't had the chance to fix it on github yet.? I have been trying a few ideas on the firmware, but no amazing breakthroughs to announce yet!? (And probably won't be any, but I'm having fun messing with it.? Maybe I'll make it display my name and callsign on the screen somewhere.)


New FW release: Added Measure functions

 

New FW released
Version V1.0-84

Changes:
- Added 4 measurement functions: SNR, -6dB width, AM and FM

See the video demonstrating these new options starting here:?https://youtu.be/ioM0Si3qI-Y?t=626

As I am no measurement expert I made some liberal use of names.
  • SNR can be used to measure the difference between a signal and the noise floor
  • -6dB width can be used to measure the width of an occupied frequency band.
  • AM does some careful AGC/LNA setting optimization to help observe AM modulation
  • FM does a quick setting to observe FM modulation.

In case you have suggestions on how to improve these function or for other measurement functions feel free to provide feedback.


New video: Measure Menu

 

A video demonstrating the tinySA Measure Menu. The video also explains some of the limitations of the tinySA and, if possible, how to work around these limitations.



Some of the measure menu options demonstrated are new and will be available in a next FW update


Re: New Tiny SA - fails self test 7 :Stopband critical

 

Hi Erik,

OK good to know.

I've checked the calibration against other test kit and it all seems good, so I'm not massively concerned.

Overall I'm very impressed, you get a lot for your money :-)

Thanks for the quick response.

Regards,

Martin


Re: New Tiny SA - fails self test 7 :Stopband critical

 

Ah, test 7, the band pass filter.
The critical part of the stop band is at a rather large offset of -4MHz from center (at the far left of the screen) so this will not have any impact on the performance of the tinySA.
The shape of the band pass filter is excellent.
I may have set this selftest a bit too strict given the (at the moment of definition) not know spread over a large amount of products.


Re: New Tiny SA - fails self test 7 :Stopband critical

 



Hi Erik,

No strong transmitters nearby.

Martin


Re: New Tiny SA - fails self test 7 :Stopband critical

 

Make sure you are not close to any strong signal/transmitter.
Please share a picture of the screen at step 7 showing the error


New Tiny SA - fails self test 7 :Stopband critical

 

Hi,

I just received a new Tiny SA from Maggie.

Recorded the config settings
Updated the Firmware to 1.0-82
Did a clear config
Did a reset
Checked config settings and all were are before.
Did a low and high band calibration

Did a self test, but this stopped at step 7 with a Stopband Critical.

What to try next ?

Regards,

Martin

Hi Jim,
I am using the Kubuntu LTS 20.04.
After this error it compiled completely.

So it should also do in Mint. It is also a Ubuntu variant with another desktop style...
You can take the github readme.md file as how-to.
The only critical error was the one with the typo in the include statement in sa_core.c.

Directional coupler instead of an LNA? If the LNA gives up it's ghost it might become conductive...

?Thankyou for taking the time to try it out. I am surprised there is not more variation in amplitude of different signals, but it does depend on the time of day. It also looks as if it would work without the LNA. I would be interested in using it as a bandscope when operating a military backpack radio (Clansman 320) which is a pain to tune across the band. It was intended for use on prearranged frequencies which were changed every day.

However, at least the LNA is a sacrificial protection in case you press transmit without disconnecting the Tinysa first! Even leaving it connected but switched off overnight could smoke it as a half size G5RV is big enoug to acquire quite a lot if static in inclement weather.

Re: OneOfEleven github pages dissapeared?

 

Short answer, the repository has been deleted.
