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
