A very interesting solution.

I get a google question to login into google account. I can fully understand that it is neccessary to login before I can POST anything. But I can not agree that I can only access something which is Open Source by READ without login. That hurts my privacy so I do not follow. Google is one of the biggest data gathering company of the world.

I do not like Apple or Microsoft, too. Microsoft is the "new" owner of GitHub. But at the moment you have full access to complete GitHub-content without login. You can use "privacy mode" of browser or (if you are very paranoide) TOR. You can read complete content. If Microsoft changes the direction: I would look for another publication method.

Sadly satoryboys GitHub is complete outdated and does not contain any of the new projects :'(

Regarding the schematics Artur has posted:

I have walked through this ~2 years ago. It is a "nice approach" - but it only solves basic issues. If you want to go near to optimum you have to bias each mixer part individually so you will need much more DACs (and much more config menu entries...)

Why all commercial have not followed this track? Are they stupid? Or have they realized that opening the box for "improvements of mixing concept" opens ten new questions when you answer one?

Do not misunderstand: I do not want to attack Yuri. I have walked through all this years ago and I realized that I have followed a track that leads to nowhere (opening one box of pandorra after the other)...

Hi Andreas,

You are wrong. See the schematic of the TRX Elecraft KX3. It doesn't say you can't use high power and the design is similar.

Hi Yuri,
Andreas is d.mn right here, if you use code based on UHSDR you must comply with the licensing.
This is hard topic, look here for summary what you can, and what you must:
https://tldrlegal.com/license/gnu-general-public-license-v3-(gpl-3) (https://tldrlegal.com/license/gnu-general-public-license-v3-(gpl-3))

So, using the GPL-3 you must (among others):
- share the sources
- share the changes compared to origin source
- share the way to build from disclosed sources

We use git tool with github which shows publicly the changes we made in code since originated from Clint and Chris. Anyway the version control tool is a must today, this would be good to learn usage of git for example.

Hi Yuri and Slawek

It seems to me that TRX Axis is very similar to TRX SParkle.
It will be two cool transceivers. I'm already looking forward to it.

@Yuri:
Please edit your firt post and correct the link so that someone who landed via Google must not dig all posts to see that the link is faulty - thank you! So Helge and I can delete our posts regarding this ::)
