What do Canadian regulations stipulate regarding frequency stability in the amateur radio service?
C
Answer
Regulations and administration
Type
A
It shall remain within 0.05% from -30 to +40 degrees Celsius ambient temperature
B
It must not drift more than 10 Hz from a governmental time signal broadcast service
C
It must be equivalent to crystal control below 148 MHz
D
It shall remain within 2 parts per million, one hour after power up
Answer Notes
Canadian amateur radio regulations dictate specific standards for equipment to prevent accidental out-of-band interference. One of these key requirements is frequency stability, which ensures your transmitted signal stays exactly where you intend it to be.
According to Innovation, Science and Economic Development Canada (ISED) rules, any transmitter operating below 148 MHz must have a frequency stability comparable to that of crystal control. This is a historical but still active phrasing that references the reliability of quartz crystals used in radio oscillators.
Options mentioning specific percentages, parts per million, or government time signal standards are common engineering specifications, but they are not the specific regulatory text used in the Canadian amateur radio regulations for equipment below 148 MHz.
