When I upgraded to General, the first thing I started working on was the ability to go portable. I live in an apartment and the noise floor on a daily basis is S7-S8. The first time I experienced an S-0 noise floor I was hooked. Stations that were barely an S2 sounded like they were in the same room with me. So I put together a list of things that might help someone else in my circumstance get out on the air.
