Handheld transmitter and range testers
Three simple tips to test handheld VHF or UHF transmitters for operation and range.
1. Handheld transmitter tester
2. Handheld or mobile transmitter range tester
This is a simple hook up to a home or mobile transceiver that causes it to send a brief signal when a transmission is picked up from the handheld or mobile transceiver you're testing. It's a bit like kerchunking a repeater. Once you get out of range it fails to respond. Access is needed to the speaker and push to talk connections. Exact details may vary between transceiver models so you may need to change some component values and connections to work with your particular rig.
3. Another range tester using a single Baofeng transceiver
This one needs an external speaker/microphone. Add a few parts and start range testing today!
