If you're interested in working the AM mode on HF, you'll find lots of conversations to listen to on the AM spot page. The AM Spot page is set up to allow AM operators to find each other more easily. The link is: http://www.amspots.com/ . You'll find routine conversations and round tables to listen to and join in on, and you can spot other AM QSOs on the AM Spots page as well. AM is an interesting mode, and you'll find folks operating everything from vintage & home brew rigs to the latest flex radios on AM. Enjoy!
