What do Canadian regulations stipulate regarding frequency stability in the amateur radio service?
- AIt must not drift more than 10 Hz from governmental time signal broadcast service
- BIt shall remain within 0.05% from -30 +40 degrees Celsius ambient temperature
- CIt must be equivalent to crystal control below 148 MHz
- DIt shall remain within 2 parts per million, one hour after power up
Correct answer: C — It must be equivalent to crystal control below 148 MHz. From the official ISED question bank, verified word for word.
Why
Canadian rules require that amateur radio transmitters operating below 148 MHz maintain frequency stability equivalent to crystal control, meaning the signal must stay locked on its assigned frequency with the precision of a quartz crystal oscillator.
