RECTIFIER SELECTION, OPERATION &MAINTENANCE
• Defective Meters: Never trust the rectifier meters. Always verify with a portable voltmeter known to be good. • Breaker tripped or blown fuse: If the breaker trips repeatedly even with the output reduced, the cause may be a short circuit in some component (much more on that later).

Variable Frequency Oscillators (VFOs)
www.qrparci.orgFor HF transmitters running on 160 meters (1.8 to 2.0 MHz) or on 80 meters (3.5 to 4.0 MHz), it’s practical to build a VFO for those frequencies. Then you may amplify the VFO signal directly. For example, if you had a crystal controlled QRP designed for 80 meters, an 80 meter VFO could be plugged directly into the crystal socket.
