Teen Aces Two Ham Radio Exams In FDL (Wisconsin)
#1
If a receiver mixes a 13.800 MHz VFO with a 14.255 MHz received signal to produce a 455 kHz intermediate frequency (IF) signal, what type of interference will a 13.345 MHz signal produce in the receiver?
A. Quadrature noise.
B. Image response.
C. Mixer interference.
D. Intermediate interference.
This rather daunting question is one the many questions on the test for your General license for Ham Radio, a hobby that has increased in interest recently all over the world. People use Ham Radio to talk across town, around the world, or even into space, all without the Internet or cell phones. It's fun, social, educational, and a lifeline during times of disaster.
