Ask Dave Episode 29 looks at the amateur radio high frequency (HF) bands and describes each. This helps hams new to HF to understand what bands will work best for them. For a PDF copy of the band characteristics chart, go to http://dcasler.com/wp-content/uploads…. The Ask Dave series answers your questions about ham radio. Thank you for watching my videos! My channel, “Ham Radio Answers,” is here to help you become an active, on-the-air amateur radio operator! I am unique in that I provide the only set of YouTube training videos that accompany the ARRL license manuals, section for section. I try hard to answer every Ask Dave question individually if I can.
