Don
I couldn't agree with you more I am guilty of this too. What books could you recommend I start with?
Thanks

Yes, it does take a bit of studying and experimenting, but is not really that difficult. If you can do simple multiplication and division, you can calculate the length of a halfwave antenna that can be used for effective communications - all it takes is some wire and a feedline.

There are formats for messages that operators should observe so the message gets to the intended recipient in an orderly fashion. The ARRL information is quite helpful for the formats and relay net operating procedures.
