All Ham Radio transceivers work on DC power. Hence, one should never plug a Ham Radio set directly to AC. Always use AC to DC converter power supply.
Check the connections twice. If you are powering the set from a battery, make sure that the positive terminus (generally in red) of a set goes to positive of the battery.
Secure these connections tightly. Make sure that wires are not open and open parts are not touching to each other.
All the transceivers have a power button. Firstly, switch on the AC supply to which you have attached your power supply. Then, switch on the power supply and finally turn on the set.
Before starting transmission (Tx) or pressing PTT (Press To Talk), always make sure that you are receiving the signals properly. Always first go for receiving (Rx) then Tx.
Many Hams rush to give CQ call. However, initially, listening is more important. Distress, Urgency, Safety, Test Signal – the various types of signals are given as per their priority. So, one must first listen to other signals.
