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

Linux Mint.? Windows isn't case sensitive, Linux is.

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.

All the TinySA tests now run properly when HI and LOW are connected via the jumper cable ...

Sorry for the confusion. ?
I meant to display an FM broadcast station and see the modulation - not actually hear the audio!

? Before you get too excited, I believe by decode Bernie meant that he can display the FM band on the low input.? The tinySA does not have a demodulated output.

The tinySa can decode the FM band nicely in LO band but I can not get the USB port to stay up in DFU mode.
30 MHz calibration signal from HP141 looks good.
Bad hardware? Bad config?
Bernie, ? The DFU mode is a special mode that allows the STM driver to flash the firmware to the tinySA.? In the DFU mode the tinySA is no longer recognized as a USB CDC device.? It is normal that you have to cycle power on the tinySA after flashing the firmware to exit DFU mode and go back to the normal CDC virtual com port operating mode. ? I'm not sure what's going on with with the self test errors.? Self test is run with the high and low ports connected together.? A -25dBm calibration signal is output from the high port is used for during self-testing of the low port.? Not a lot can go wrong unless the calibration signal level is off (earlier firmware had that issue) or the connection between the low and high port is faulty. ?1. I would first check to ensure the latest firmware is installed, 1.0-82 will be displayed in the tinSA status pane if you have installed the latest update. ?2. If the latest firmware is installed and you still have selftest errors, then I would use the second sma cable to run the selftest.? If swapping cables solves the problem then you have a bad cable. ?3. If neither of the above work, then Erik can guide you through further troubleshooting. ?Erik is in a different time zone so it will be a few hours before he reads your post. ? - Herb ??

Re: New video: Level menu
It's there, you just have to hover over the word "video" in your original post to see it and click it to go to it. I think if you just paste the link in the text without using the link button most stuff will pick it up as a url just fine. Like:??(no link button used to create this even in the groups.io editor)
