HF Band

30 meters band

“WARC band”

30 meters is a narrow, contest-free WARC band reserved for CW and digital modes — quiet, efficient, and open through much of the day and night.

Frequency 10.100–10.150 MHz
Spectrum 30 m · HF
Primary modes CW, FT8/digital (no phone)
Half-wave dipole ≈ 46.2 ft (14.1 m)

Propagation & character

It bridges 40 and 20 meters: frequently open to DX in daylight and holding up into the evening, with low noise and reliable paths.

What 30 meters is used for

CW and digital only — FT8 is especially popular here. No phone operation, and no contesting by long-standing agreement.

Operating tips

  • US power is limited to 200 W PEP.
  • With no contests and no phone, it is a relaxed band for DX and digital ragchewing.
  • A 30 m dipole is about 46 ft.
