Ham Radio

If the operator is just giving their position with a Maidenhead locator there should allready be some inaccuracy (depending on how long the locator is).
In Germany it's also fairly easy to find a ham's address, unless they choose to not show it in the public database.

Obscuring locations makes me feel better, but as you say, it means close to nothing. I wouldn't bother.

I am trying to understand how the coordinates end up in the system. https://www.rwardrup.com/dynamically-mapping-amateur-radio-packet-stations/ suggests that it is an automated process by scanning the system. So, the coordinates must be collected from resources already publicly available, right?

But then I also found https://form.jotform.com/210773558931159 which seems to be a form to manually submit data where coordinates have to be added.

As a general rule: if the information is accessible just by decoding packages sent over the air, then there is no need to add a jitter (assuming some sort of metadata managed by the node owner). If this is not the case, then I see two options:

1. Consent by the operator of the node: show real data.
2. No consent: a jitter is in order.
