ARLA/CLUSTER: Pré-proposta da ARRL para um novo plano de banda nos 40m

[João Costa > CT1FBF]

ARRL Draft HF Band Plan Proposals

The ARRL HF Band Planning Committee has concluded that it would be
unrealistic to try to bring the ARRL 40m band plan into alignment with
the rest of the world

They say that in Regions 1 and 3 where 40m operating patterns
developed when the entire band, including phone, was just 100 kHz wide
and is still only 200 kHz. While 7040 kHz is a recognized RTTY/Data DX
frequency in the band plan, the best place for other RTTY/Data
activity in the US is above 7070 kHz.

80 through 10 meters — excepting 60 meters at

For 35 years the development of Data Modes in the USA has been
crippled by the symbol rate restrictions introduced at HF and also
VHF/UHF in 1980.
