Seeing more posts about band edge confusion lately, especially with the recent FCC changes to data bandwidth limits. Here's a systematic approach to ensure you're always operating within your privileges:

• Know your license class limits - not just the band, but the specific segments
• Account for signal bandwidth - your signal extends beyond the carrier frequency
• Check mode restrictions - some frequencies are CW/data only
• Verify power limits - especially important on 60 meters and above 50 MHz

What other steps would you add to this checklist?

Great checklist! I'd add "Monitor before transmitting" - even if you're in the right segment, listen first to avoid QRMing ongoing QSOs. Also keep current band plans handy since there may be updates to the ARRL Band Plan in 2024 to improve efficiency and reduce interference.

Don't forget spurious emissions! The FCC defines spurious emissions as frequencies outside necessary bandwidth that can be reduced without affecting transmitted information. Your rig might be clean on the fundamental but harmonics could be violating other services. Regular equipment checks are essential.

Add "Know your equipment's actual frequency accuracy" to the list. I've seen older rigs drift enough to put operators outside their allocated segments, especially on 60 meters where hams must transmit on specific channel center frequencies. A frequency counter is a good investment for serious operators.
