Popular Digital Frequencies (approximate dial)

FT8 and FT4 have become the dominant weak-signal digital modes. Typical USB dial frequencies (Region 2):

Always listen first and follow local band-plan recommendations. Some segments are shared or have power restrictions.

Licence / Regulatory Notes

Licence privileges are country-specific. Do not infer legal privileges from the convenience tables above. In India, verify the current WPC / Ministry of Communications licence conditions; in the US, verify current FCC Part 97 rules; elsewhere use your national regulator.

This page is a convenience summary only. Official allocations are defined by FCC Part 97 and the current IARU Region 2 band plan. Rules can change; check the ARRL band chart or FCC website for the authoritative source.

How to read a band plan correctly

A band plan is a practical operating guide, not a substitute for the regulations that define what a licence holder may transmit. Frequency allocations, emission privileges, power limits and special sub-bands can differ by country and can change as regulators update their rules. The values shown here are therefore best treated as an orientation tool for the stated US / IARU Region 2 context. Operators in India and elsewhere should check the current rules published by the responsible national authority before transmitting.

It also helps to separate three ideas that are often mixed together: the legal band edge, the portion commonly used for a particular mode, and the frequency range currently preferred by a local operating community. CW, SSB, digital modes and weak-signal activity may cluster in different parts of the same amateur band. Contests, nets and propagation openings can temporarily increase activity around familiar frequencies without changing the underlying allocation.

When planning an antenna or selecting a frequency, start with the legal allocation, then check the current regional band plan and finally consider local operating practice. Leave reasonable guard space around edges and ongoing QSOs. For digital modes such as FT8, remember that the software's normal operating range is only a convention; it does not override national frequency rules. This page should be used as a quick reference alongside current regulatory and amateur-radio organisation sources.

Allocation versus operating convention

A band plan is not the same thing as the legal allocation itself. Regulations define what a licensed operator may transmit, under which conditions, and which portions of a band are available to particular services or licence classes. Amateur organisations then publish operating conventions that help operators share spectrum efficiently. A commonly used SSB or digital frequency is therefore a useful operating reference, not a guarantee that every station may use that frequency in every country or mode.

This page uses a US / Region 2-oriented reference because operating conventions vary by country and sometimes by licence class. Before transmitting, check the rules that apply to your station and the current regional band plan. Digital-mode frequencies also deserve extra care because software can display a dial frequency while the actual transmitted signal occupies a wider passband around it.

Use the band-plan reference alongside the propagation page and your transceiver's mode and filter settings. That combination answers three different questions: where you are permitted to operate, where other operators commonly listen, and whether current conditions make the band worth trying. The calculator cannot make the regulatory decision for you.
