Bingo, you hit the nail on the head [for me]!
I understand the need to have a "line" (criteria), but there is no "line" for what is attached in the form of enhancement - antenna - & that always seemed contradictory to me (a radio like the D-808 that is .76 cubic inches above the "line" - which confirms a contradiction as some EXclude while others INclude).
I subscribe to this list because I enjoy reading everyone's logs and reports of what they capture - I find it interesting. Some inspire me to strive for the same - the posts of people using the same or similar radio. The fact I'm not using a wheeled cart or milk crates to transport or move my [ultralight radio] antenna does not detract from the interest I have of reading that someone captured a medium wave signal across the ocean. That's a "wow". But the latter is not me - and that's perfectly fine - to each, his or her own.
But I'd never post my logs and I would never go for an award or a record because of my confusion (contradictions). But that's fine, too. I get inspired from this list. And I have a spreadsheet with my own personal "hall of fame" within my bald head ;-) My set-up is probably the equivalent of a Smart Car - I just can't compare what I do to someone using a racecar or a tractor trailer especially through a blurry lens when some include while others exclude the same "car".
I really appreciate the open discussion. Cheers to all ... and keep DX'ing, use whatever you want, and get others involved (I'm trying to inspire my 30-something son to get into the hobby)!
