On what frequencies are spread spectrum transmissions permitted?
Only on amateur frequencies above 50 MHz
Only on amateur frequencies above 222 MHz✓Bonne réponse
Only on amateur frequencies above 420 MHz
Only on amateur frequencies above 144 MHz
Explication
The emission table first authorizes spread spectrum at 222-225 MHz on the 1.25-meter band, and on every band above it. The 219-220 MHz segment just below is restricted to data forwarding, and no HF or 6-meter allocation carries spread spectrum at all.
