Introduction of band plan by bandwidth. CW segment extended from 7000-7035 kHz to 7000-7040 kHz. Narrow band modes, digimodes segment moved and extended from 7035-7038 kHz to 7040-7047 kHz.
Non-contesting radio amateurs are recommended to use the contest-free HF bands (30, 17 and 12m) during the maximum bandwidth not specified, 500 Hz suggested Voice mode should be 3 kHz below upper band edge on bands 20m to 10m.
16 Οκτ 2020 · HF Bandplan. After approval by the Virtual General Conference in Novi Sad 2020, the modifications of the Region 1 HF band plan became effective at 16 October 2020. VHF & up Bandplans. The VHF band plans are kept under continuous review and the latest versions can be accessed via the above link
Digimodes. Any digital mode used within the appropriate bandwidth, for example RTTY, PSK, MT63 etc. (*) Lowest dial setting for LSB Voice mode: 1843, 3603 and 7053 kHz. NOTES. Amplitude modulation (AM) may be used in the telephony sub-bands providing consideration is given to adjacent channel users. (NRRL Davos 05).
1. Introduction. The concept of a band-plan based upon emission bandwidths was put to the IARU Region 1 HF Committee in 1992 by DARC. The idea was prompted by the emergence of new modes, changes in usage of existing modes and the need to ensure spectrum efficiency.
Introduction of band plan by bandwidth. CW segment extended from 7000-7035 kHz to 7000-7040 kHz. Narrow band modes, digimodes segment moved and extended from 7035-7038 kHz to 7040-7047 kHz.
This document provides the IARU Region 1 HF band plan, which is a recommendation for how radio amateurs should use the HF bands. It lists each band from 2200m to 10m, the maximum bandwidth, and preferred modes and usage within each segment of each band.
