Shortwave Notes …

Test before transmission …

Most modern SW radios have a bit or built in test. This test allows you to test your transmission strength BEFORE using the radio – using squelch from the hand set button. Be sure to test before transmitting – if you don’t have a good test, you can damage the radio.

Adjust lip on wire coil at base of antenna: up (shorter wave length in meters), down (longer wave length in meters). Daytime is shorter in meters, night tends to be longer wave transmission mode.
