Re: [digitalradio] Re: HF International Automatic Subbands
Bonnie, Just a point... 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 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.

Re: [digitalradio] Re: HF International Automatic Subbands
When there's no emergency underway, however, the automatic bands are available to all amateur stations, not just unattended stations. Its no more acceptable for unattended stations to QRM ongoing QSOs in the automatic bands than it is to QRM them anywhere else within the amateur spectrum. 73, Dave, AA6YQ Excuse me for being so dumb, Dave... what is the purpose for allowing unattended stations in a specific part of a band if they have to listen to make sure a frequency is clear? I don't get it. Also, am I wrong in thinking that unattended versus automatic means the same thing? Hmm, in thinking back to the days that all this may have started, packet days, I remember that my TNC would not transmit a packet if the TNC detected another station, it would wait a second or two. is this the difference , that unattended with busy detect is fine ?

Re: [digitalradio] Re: HF International Automatic Subbands
I agree 100% - and I operate an automated Packet station in one of the sub-bands. Fairly often, on weekends I see a good deal of RTTY contest activity there, and the RTTY guys have proven to be good nieghbors. I use MixW as an HF Packet modem, which allows me to open up a second or third window in RTTY mode and read the mail during the contests. Seeing how much fun those guys have, I've decided that if I ever get into contesting, it will be in RTTY mode first. 73 DE Charles Brabham, N5PVL Prefer to use radio for your amateur radio communications? - Stop by at HamRadioNet.Org ! http://www.hamradionet.org - Original Message - From: aa6yq To: digitalradio@yahoogroups.com Sent: Monday, November 23, 2009 7:34 PM Subject: [digitalradio] Re: HF International Automatic Subbands During an emergency, no one has a problem ceding frequencies to emcomm stations; its like heading for the shoulder when you hear an ambulance while driving.

RE: [digitalradio] Re: HF International Automatic Subbands
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.
