Hi Dick, Probably the best we can hope for is a documented snapshot of a point in time. As an example of such a snapshot, earlier in 2008, a research project by HFLINK was completed, and a chart produced for the upper part of the 30 metre ham band: http://hflink.com/bandplans/10mhz/ We all must keep in mind that the digital modes are in a constant state of evolution, and the various frequencies that are haunted by these modes, ops, nets, and groups are changing over time as well. Some digital ops follow the mode fads... extremely popular for a few months and then fade away... like hoola hoops and pet rocks. The http://bandplans.com website is a good resource, very well done, however, it suffers just a little from TMI (Too Much Information) for presentation in spreadsheet list format. Some of the listings are over-reaching, conceptual, obsolete, mis-categorised, or wrong. But, most of the listings are excellent. It is probably the best starting point for digital mode ops to understand the ham band spectrum landscape. Whoever pointed the questioner to the ARRL website was quite humorous! ARRL resources in this area are a joke :) For some reason, ARRL has never really provided up-to-date listings, practical advice on digital mode operating freqs, or leadership in this area. Perhaps they don't want to wade into such a barrel of monkeys. Only recently did ARRL add the automatic subbands to their considerate operators frequency guide, even though it has existed for many many years! 73 Bonnie VR2/KQ6XA

We all must keep in mind that the digital modes are in a constant state of evolution Are you saying there is no standard ? If so how can you set calling frequencies ? NOTE . SSB, AM, CW and FM can be coped by 50 year old as well as 50 hour old radios.

Alan: I've been attempting to establish a list of a suggested frequencies to be used with the various digital modes in Region-Two for quite some time. I found bits and pieces of several of the HF bands have been set aside for RTTY and PSK 31. It appears that everyone accepts to 14.0700 MHz as the frequency for PSK 31.. further action in developing digital band plans seems to stop at this point. I have seen several lists that appear to be well thought out. The problem seems to be that after the lists are compiled nothing is done with them. A post to you from Bonnie, VR2/KQ6XA, contains what I think is a very comprehensive plan. I would love to say I vote f will move or this, amen, put it into action. I do not feel that assignment of the digital sub bands needs approval of any type of committee or radio official. If this afternoon we say, Bonnie's suggested plan is approved, and each of us immediately put the plan into action through our operations on the bands, by spreading the concept by word-of- mouth, and publication of the band plan on amateur radio oriented websites and we would have a working digital band plan by the end of August. Can I get any amen's for this? If so-let her rip.Alan: Dick Zseltvay, KC4COP --- In digitalradio@yahoogroups.com, Alan NV8A [EMAIL PROTECTED] wrote: Is there a list of generally accepted HF frequencies for digital modes in Region 2 somewhere? 73 Alan NV8A
[digitalradio] Re: Frequencies for digital modes
Bonnie suggested two URLs: 1. http://bandplans.com/ 2. http://hflink.com/bandplans/ The first starts out by saying this site is not intended as any kind of recommendations for the band usage. It merely records the users of the amateur HF bands 6 meters. Some band usage is controversial. Our job is not to make judgement either ways... if there are multiple users for certain frequencies, we will happily record both of them. Our rule of thumb is: if you can hear QSOs on those frequencies, we will happily accept an entry. While this site contains information that is useful in the band planning process, its not a bandplan. Bonnie's second URL provides links to many band plans. One of those links is to the IARU region 2 bandplan: http://www.hflink.com/bandplans/Region_2_MF__HF_Bandplan_Annex__1_2008 .pdf This is dated 2008-01-01, as states It is suggested that Member Societies, in coordination with the authorities, incorporate it in their regulations and promote it widely with their radio amateur communities. However, this URL's link to the ARRL new proposal... is to a bandplan proposal that the ARRL has withdrawn: http://hflink.com/bandplans/ARRLBandwidthBasedProposalCharts.pdf The current ARRL bandplan is available via http://www.arrl.org/FandES/field/regulations/bandplan.html 73, Dave, AA6YQ --- In digitalradio@yahoogroups.com, kc4cop996 [EMAIL PROTECTED] wrote: Alan: I've been attempting to establish a list of a suggested frequencies to be used with the various digital modes in Region-Two for quite some time.

As there is not only Region II here is the link for the existing official Region I bandplan: http://www.darc.de/bandplan/pdf/kwbandplan_col_eng_1.pdf Please note that this bandplan is mandatory for some countries (e.g. Germany) and not just an option somebody may follow or not. 73 Juergen, DL8LE --- In digitalradio@yahoogroups.com, Dave Bernstein [EMAIL PROTECTED] wrote: Bonnie suggested two URLs: 1. http://bandplans.com/ 2. http://hflink.com/bandplans/ The first starts out by saying this site is not intended as any kind of recommendations for the band usage.
