Jim this description is spot on. If you live in a neighborhood, take a good portable battery operated receiver (FT817, KX2, etc) with a wire hung in your backyard. Take readings of noise floor, birdies, etc of all your bands you use. Then go to a forest and do the same. It will blow you away at the difference. Done it many times. First time I did that years ago with an FT817, thought surely something must be wrong with the rig. Rig was fine.

Most hams are bathed in RF noise from all the stuff in their homes, and the homes of their neighbors generating trash that we don't realize how noisy any individual product is. For that reason, I NEVER trust observations that a device is quiet unless I know that the ham has carefully probed it with a battery operated radio held very close to it, and to all wires connected to it. These links talk about how to do that.
