This is true that only the FCC has set up automatic sub-bands.
Most other countries adhere to the RECOMMENDATIONS of the IARU with respect to where and how to operate but these do not carry the force of law. This, and years of good operating practices has defined band operations. In Canada, amateurs are limited to a maximum power output, and a maximum bandwidth (6khz) except on 30M where it is 1khz bandwidth. Even with the freedom to operate any mode anywhere, the vast majority of operators more or less follow the established band plans.

I don't believe the HF automatic sub bands are internationally recognized. To my knowledge it is only the FCC in the US that has set up these automatic control sub bands. 73 Dave WB2FTX ----- Original Message ----- From: expeditionradio <mailto:expeditionra...@yahoo.com> To: digitalradio@yahoogroups.com Sent: Monday, November 23, 2009 7:21 PM Subject: [digitalradio] Re: HF International Automatic Subbands > I would also like the ALE and digital community to > recognise that they share the bands with everyone else > Dave (G0DJA) Hi Dave, While I can't speak for the whole "digital community", I can probably speak with some authority for the "ALE community"... ALE operators have been sharing the ham bands for many many years without harmful interference. This is primarily due to the way that ALE has been adapted to amateur radio by hams, a protocol adaption known as "ham-friendly ALE". 99% of ALE operation is in organised emcomm networks and 99% of the organised networks are operating in the internationally recogised HF automatic sub-bands, where automatic modes have been in use for many years. 73 Bonnie VR2/KQ6XA _____ No virus found in this incoming message.
