I'm a relatively green general and have only made a few contacts on HF (2 from calling CQ and a few others from checking into nets, special events and contests). My question...what common mistakes do new guys make on HF? I made the mistake of transmitting out of my permitted frequency last week. I had printed off a band plan from some website and didn't immediately realize the chart was old. When I looked at the ARRL site a few days later, it dawned on me that the transmission in question was in a frequency range reserved for extra level phone, not the general level. What else do the new guys tend to screw up?
