Looking for a definition? The Glossary covers licensing, operating, equipment, propagation, satellites, events and emergency terms in plain language.
We host Apache-2.0 Polo documentation screenshots (Ham2K docs repo) and our 4WAVE photos. N3FJP / POTA FAQ screenshots stay on their sites — those pages are not an open license. Templates and SVG diagrams below are original.

Recent rule changes (as of Oct 2026)
Part 97 has changed several times since 2024. Old books, videos and forum posts may predate these changes. This box was checked against the Federal Register and eCFR (current through Oct 1, 2026) on 2026-10-08. It's a summary, not legal advice.
| Effective | What changed | Source |
|---|---|---|
| 2024-01-08 | The HF symbol-rate (baud) limit was removed for data emissions on the bands where it applied. It was replaced by a 2.8 kHz bandwidth limit (§97.307(f)(3)). 2200 m and 630 m keep their old limits. | 88 FR 85126 (WT Docket 16-239) |
| 2026-02-10 | Obsolete Part 97 provisions deleted in the FCC's "Delete, Delete, Delete" cleanup: §97.27, §97.29, §97.315(b)(2), §97.521(b) and Appendix 2. Little effect on day-to-day operating. | 90 FR 57698 (GN Docket 25-133) |
| 2026-02-13 | 60 m reworked: a contiguous 5351.5–5366.5 kHz segment at 9.15 W ERP, plus retained channels at 100 W ERP, General and above. | 91 FR 1405 · our 60 m page |
The band-plan checker uses these rules, including the 2026 60 m segment and channels.
Still pending (watch list):
- VHF/UHF and LF symbol rates. A 2023 FCC proposal would remove the remaining symbol-rate limits on 2200 m, 630 m, 6 m, 2 m, 1.25 m and 70 cm (FNPRM, FR 2023-26769). As of the Oct 1, 2026 eCFR, the 19.6 and 56 kilobaud limits are still in §97.307(f)(5)–(6).
- Other modernization requests. ARRL asked the FCC in April 2025 to act on these and on other items, including updated Technician privileges (RM-11828) (ARRL comments). No final rule as of this check.
