From the professional radio technician’s perspective…field testing to triage a radio.

  1. Does the radio power on? If not check the power source for voltage (i.e do you have 12V or try a spare battery).
  2. Hook the radio up to a Wattmeter with a dummy load on the output and see if it is generating power. If not you’ve likely suffered a component failure. Of course this can’t be done with most FRS radios.
  3. If it makes power, check for forward/reflected power on the antenna (if it’s a mobile/base) or check a known good antenna (if portable).
  4. If you found an anomaly on the antenna (assuming mobile) disconnect the feedline from the radio and remove the antenna. Using a multi-meter, check the center conductor and the shield for a short, none should be present. If a short is not present, try a known good antenna.
  5. If you still haven’t figured out what is up, the radio needs to be checked on a service monitor.

You answer this very professional,

It would be better if there were test instruments to measure the launch and reception.
