Release EU1KY AA Firmware CEC Version 1.01 and 1.0a
It is the stabilized final version of EU1KY AA. Updates starting with Version 0.1 continue to add features. Please refer to the link below for added features.
I have separated the Version to 1.01 and 1.0A for users who want to use AA only for instrumentation purposes.
* If you want to use all the features added up to Version 0.71, please use Version 1.0A.
* If you want to use it only for instrument use, please use Version 1.01
Version V1.0A
Version V1.01

5. Conclusion
I am always thankful for EU1KY and DH1AKF. I have only added a few features to the great equipment they have created. AA was a great device before I improved the firmware.
I had plans to add a little more functionality. But with so many features, the antenna analyzer is getting more and more complicated. So I decided to stop adding features at this point.
I have divided the version into V1.01 and V1.0A for users who want to use this AA only as an instrument.
Started develomemt project for my main work. In addition, a seasonal semester in which daily lectures are required has begun. Because of these things, I will not be able to actively work on Open source projects for a while.
If the busy day is over, I am going to work on a small MCU with FT8 and FT4. FT8 probably seems to have progressed by about 90%. If this succeeds, we will be able to mount the FT8 protocol on quite a few transceiver. This is my little dream.
Thank you for using the firmware.

Thank you Ian!
ReplyDeleteA question, I was using v0.53. If I update the firmware to v1.0A, do I need to perform another hardware calibration? And should I format the SD Card first?
Or, is it OK to upgrade from 0.53 to 1.0A without doing any re-calibration or SD card formatting?
Cheers
Hello Ian,
ReplyDeletejust a small anomaly noticed, not sure if this is found on earlier versions.
When in the single frequency menu with smith chart, the green dot does not update with minor changes of impedance. Although the R and X values show Z changes instantly. Unless the screen is exited and re-entered does the green dot update its position.
It requires a large change in R and X values to see the dot display update otherwise.

The firmware support 1300Mhz AA?
ReplyDeleteHello lan,
ReplyDeletethanks for the great software. I have only a question : where are the difference to compile the source between V1.01 and V1.0A ?
I have see that the VNA boards have now a connector for bluetooth, but i didn´t found something in the source to configure it. So i will add this part in the source.
Hi Ian,
ReplyDeleteBeen experimenting with your version (now 1.01A) for a few days and it looks very nice. On thing though, the VNA S21 Gain functionality seems very inaccurate. I did a TX(S2) Strenght calibration first, then an S21 measurement with a cable between output and input, this gave a nice 0-dB ish line. However when I do actual measurements with filters or just some good quality attenuaters the graphs are just way off. See for instante https://www.pa3bca.com/20DB_ATT.png , this is a measurement with just a mini-circuits 20 dB attenuator. Should gave a solid -20dB line?
