Don't try to transmit without a license. Don't connect the lightning-switch to an inside ground.
                  *               *                  *               *
Don't forget that tube sets are far more efficient than crystal sets. Don't use iron for an aerial.
                  *               *                      *               *
Don't handle the crystals of your set. Don't forget to keep the aerial and lead-in insulated from all other objects.
                  *               *                      *               *
Don't try to get a fine adjustment while touching the detector with bare hands. Don't expect to get good results with an aerial less than 100 feet long or low down among other buildings.
                  *               *                      *               *
Don't fail to make  good connections. Don't run your aerial parallel with electrical wires, elevated tracks or steel bridges.
                  *               *                      *               *
Don't forget to scrape off the insulation and have wires bright before making connections. Don't forget that a good ground is necessary.
                  *               *                      *               *
Don't cover joints with adhesive tape; use "spaghetti" or varnish cambric tubing wherever possible. Don't try to use your instruments just before, just after, or during a thunder storm.
                  *               *                      *               *
Don't oil any portion of a set. Don't be discouraged if the first galena crystal you try is not very sensitive.  Try a number of pieces.
                  *               *                      *               *
Don't blame your set until you are sure it is not your fault that something is wrong. Don't rush blindly at the set and turn knob and handles hit or miss if anything goes wrong.  Be calm and patient and go slowly.  Haste makes waste in radio as in all things.
