Ask Dave – Episode 2 – A Tour of the 20-meter Ham Band

This week’s installment is built around a response to a question from Justin Smith, AF7QN, who asked about calling CQ and where to listen for a response. That question sparked this tour of the 20-meter band for the new General or Extra, or for those hams who might like to try something new.

The key graphic showing the highlights of the 20-meter band can be found by clicking here.

Please comment! Let me know what you think of the format, and what I might change. You can ask questions directly by going to the Ask Dave! page by clicking here.
