Dear Sirs, I'm Carlos G. Correa, PY1483SWL, and I come here to turn to SWARL for what I am going to expose.
The listening activity is very old, even older than amateur radio, since there was already listening to commercial radios around the world. It was common for radios to receive confirmation cards that they responded by sending cards, streamers, flyers with the radio's programming, among others. It was not uncommon for these radio stations to have staff dedicated to listening in their programming, which motivated the growth of the SWL movement.
The first years
SWARL was started on the internet by Tim Kyle on Listbot (http://web.archive.org/web/19991011221521/http://swarl.listbot.com/) but after awhile Listbot was taken over.
Radio wasn’t made first as an advanced broadcasting station but it was made like a little amateur station. There were people who were operating transmitters and sending signals "on air" but those operators wouldn’t have any meaning if there wouldn’t be a wide audience of listeners.
