I would look at such a domain as a cover domain for the actual DoorToDoor.com name (which it appears from your sig, you also hold). Likely the one who acquires DoorToDoor.com is your largest interest buyer for DoorTooDoor.com and they may or may not know/care about the radio test. FWIW, they will probably also need DoorTwoDoor.com and Door2Door.com to complete the set to pass the radio test if they even know/care about such things.
Some get the importance of having the cover names. Personally, for some of our names, I'd value the cover domains at reg fee, but for others... Your mileage may vary. Don't drink and domain.
if your domain used the word spelled this way “” MeToo.com “”then you would need to buy MeTo.com , no one Gets it wrong the other way,I really see no value in this domain.
