Is the [radio] tag necessary?

Question

There are 18 questions tagged radio. I am proposing deleting it, as it is largely redundant and confused with other tags.

• 10 are also tagged radio-communication.
• 2 more are tagged radio-astronomy or radio-telescope.

Questions with remaining tags that seem sufficient:

• What is required to make GPS signals available indoors? gps
• Could we use a narrow paradigm, say laser, to get info faster from New Horizons? (With a moon base.) communication laser
• Was it a "Soviet military satellite not in any of the catalogs?" artificial-satellite military seti

Propose replacing communication to radio-communication:

• Apollo communication between the Earth and Moon the-moon nasa apollo-program communication

Propose adding radio-communication:

• How much power does the Voyager radio dish draw? voyager power dish

Not really about radio (delete the tag):

• Looking for a live audio-only stream of NASA TV or JSC/ISS loops

Answer 1

I've gone ahead and adjusted tagging on:

• Was it a "Soviet military satellite not in any of the catalogs?"
• Is the recently discovered VLF-induced radiation barrier in any way important or useful?

Everything else stated at the moment seems okay to me.

Answer 2

I can agree it with the condition that it does not destroy content.

All the removed radio tags should be replaced by a more specific one (radio-astronomy, radio-communication, and so on). So it is not deletion, but improvement (more specific tag -> more information). Or any edit is okay, if the total information content (measured in bits) grows and does not decrease.

Answer 3

I have gone ahead and appropriately re-tagged all 18 questions. The tag is now empty. Could a mod please delete it and set this meta-post status-completed?

Future questions should use radio-communication, radio-astronomy, or radio-telescope as appropriate.
