 Hi Phil et al,

Thanks for the additional details. And thanks for doing such an excellent job steering the superb and wide-ranging sessions at the NEWS Conference!

As you know, and as you point out, it is not really an "either / or" situation.

I believe that the cluster will work very well as the first mechanism for finding out who is on and available in a busy contest environment when "yet another window" will often get lost in the shuffle among the many open windows already present on multiple screens. It is for spotting new stations, and can also be used for brief messages, as others have noted. The potential use of the cluster as a gateway for station info from other sources [SMS, APRS, twitter], as was discussed at the Conference, is exciting to say the least. Cluster use will be like its use in HF contests, with additions and modifications as desired/required by those of us using it for VHF and up.

As you point out, there is certainly a role for ON4KST, and I plan to use it, but not for the purpose of spotting during a busy contest! ON4KST comes into its own as a liaison channel for stations to use to work out the details of their contacts. It is also useful for a less busy station in an area where there is much less "going on" during a contest than there is in the busy corridors on the left and right coasts, where there isn't so much to keep an eye on that adding an extra window that needs to be constantly watched is counterproductive. My sense is that ON4KST will work much better in contests such as the Sprints/ARRL 10 GHz / ARRL UHF contests where things are "quieter" and there are fewer bands to watch than during the Jan/June/Sept contests when things are extremely busy and there are many bands / windows to keep an eye on.

What works best on the coasts might be much different that what works best in the middle of the country. These are examples of different regions, and it will in my opinion not present a problem if different regions find different solutions for their different environments. And what works best in one type of contest may be different than what works best in another type of contest. One size does not fit all. But within a region, best results will be achieved if there is a common approach to the problem. The fact that Phil and I and others in the North East are going to start by using the cluster for spotting and ON4KST for liaison/chatting does not preclude others elsewhere from choosing other approaches.

I will be on for the 432 sprint tonight and will make use of both of these tools, using the cluster for spotting and ON4KST for liaison, or when things are slow.

An example of how my contest screens will look for the Jan/June/Sept contests is at:

The cluster window is top right.
Note that when this screenshot was taken:
1.  The radios were not "on"
2.  Cluster filters were not engaged
3. The browser was set to display aprs.fi , as it would be during a contest to keep an eye on rovers. 4. I DO have a chat page up on the browser [WSJT EME Link], though it is not displayed. During an actual contest I will also have the ON4KST page up, but it will not be displayed except when in use.

It's time for me to stop the digest and get these emails directly. So glad to hear the comments coming. There is a solution out there and I think it will be a combination of several things. ON4KST is a great choice for when you have the time to chat. One of the brilliant things about that page is that it does include a filtered display of spots. Most of what I've seen is EU spots, but we can change that by generating our own NA spots as well. At times it may be necessary to consult the chat page to gain that new grid / multiplier, but when the going is fast the place to stay is usually the logger when you are busy and the major loggers are all set up to present filtered spotting activity to your attention. It's a proven tool in very busy (HF) contests. Why not use what we already have in our hands. My belief at this time is that the existing amateur radio cluster (which seems to be used heavily by the EU crowd) should be at the core of our common attention gathering efforts. One of the thoughts that came out of our initial workshop was to employ a gateway to feed the cluster. For instance we can take APRS data gleaned from Rovers who are ready and in position to operate and post it to the cluster. This covers Rovers who may not be in cell phone range at their location. If they do have coverage it will be possible for this gateway to put an APRS message out on the cluster or to take a twitter feed and put it out on the cluster. As has already been mentioned there is a talk mechanism that allows private messages to be passed between cluster users; we need to pursue that further. These messages show up in a logger window in Highlighted fashion. Several of us did some experimenting with this function in the 222 sprint. There is much to discover, and perhaps much to develop further here. My next task is to evaluate further the internal schema of the cluster traffic to see just what latitude we have going forward. I know that there are at least two cluster programs being used; AR-Cluster and DX Spider. There seems to be a difference in capability here which we need to explore. Is there anyone out there in the VHF community with intimate knowledge of these features? There are also opportunities to build more functionality into the loggers that we use. I'll stop rambling now. Perhaps we can start a few separate threads here to keep focused on how we can really make the new rules work to our mutual advantage.
