Ham radios provide two-way radio communication, like walkie-talkies with much greater range and much wider application. The operators themselves, called “Hams,” are as diverse as the range of signals they can receive on their systems. Each person has designed their set the way he wants it, often using Kenwood transceivers. Building the set is part of the fun, but as dependable as Kenwood has proven to be, there are always little glitches. Knowing a few troubleshooting techniques can add to your enjoyment of this hobby.

Instructions

  1. 1

    Check that all switches are in their correct positions and the AC power is on.

    Examine the condition of all cords and the state of their connections to the transceiver. Tighten or replace them as necessary.

  3. 3

    Clean or replace any blown or worn fuses.

  1. 1

    Correct the sideband signal by resetting the "Mode" switch to a different SSB position, if you can’t make sense of any communications.

  2. 2

    Move the "Mode" switch to the clicked position in the centre of the control if the signal seems too high or too low.

  3. 3

    Improve the SSB’s audio by moving the antenna away from the transceiver or by re-grounding the microphone.

  1. 1

    Reset the VOX control by turning it clockwise from minimum or manual to the VOX position to make the circuit operate.

  2. 2

    Correct the "Anti VOX" setting, which closes voice transmission, by moving it clockwise to decrease the VOX’s sensitivity and stop it from reacting to sounds from the speaker.

  3. 3

    Adjust the time-delay to greater or lesser on the hold control if you are hearing pauses in the transmission.

  1. 1

    Return the microphone’s Push to Talk (PTT) switch to receive if there are no signals coming into the receiver.

  2. 2

    Adjust the carrier (CAR) or MIC controls by turning them clockwise if the microphone is not transmitting.

  3. 3

    Reduce the power of the MIC control by turning the knob counter-clockwise if the signal is distorted.
