Troubleshooting handheld vhf

Recommended Posts

Waste of time? Throw out and replace? Handheld seems to receive, transmit button makes a noise, but no speech can be transmitted. Older small Standard Horizon.

Was it a handheld that got used a lot? If so, the PTT button contacts may be messed up, worn or dirty. If you can take apart the PTT button and clean the contacts that may bring it back to life.

Also, soaking the switch in some electronic contact cleaner may help wash the internals of the switch clean. 

 

(PTT = Push To Talk)

Does it have a WX button that does not respond? Could be another switch that needs cleaning. As a general rule, the mechanics of these devices (Switches, battery contacts, etc) tend to fail more than the electronics (chips, transistors circuit boards) 

 

Not always the case (electrolytic capacitor  fail a lot) but its a common theme.
