Note that GPS receiver capable (i.e. not artificially limited) of providing navigation data while moving 600 m/s or higher used to be considered munition by ITAR. The amount of legalese at updated ruling [1] is well beyond what I can make sense of, to the point I don't even know if it still applies.

While we're at SDRs, ITAR is also responsible for takedown of passive radar GNU Radio module made by Kraken RF team.

I did some brief searching of their Twitter feed and in general but couldn't find any update on this. Does anyone know the current state of passive radar and KrakenSDR?

Comment thread from 2023-02-10:

> We are attempting to clarify if it is legal for us (KrakenRF, a US company that provides a physical SDR product) to also provide our own open source software that is made by us. As that could be seen as providing a full PR system.

Is the latest I found from them.

The lawyer likely advised not talking about it more publicly.

Almost any lawyer won't present the world as black and white, but rather in quantities of risk - and even saying "we've taken the project down and it wont be coming back" is a risk if that attracts attention to your past distribution of the software and causes others to mirror it from archives.

Would it make sense to make some disclosure of "it's not coming back and no PRs adding similar functionality will be entertained for this reason?"

Additionally, it seemed like this page[1] (discussed previously[2]) details some reasons why some publicly visible source code projects should be able to include code that implements things otherwise under export control.

> quantities of risk

Even that’s asking for a lot.

Qualities of risk is more likely.

IIRC everything they took down was in the Git repo history.
