Im not sure if this is feasable but with regard to the antweights here are my thoughts.

1. There is no point in trying to get the ants onto 27mhz because most people have invested in 40Mhz equipment. Although I appreciate that some ants do run on 27Mhz.

2. The solution would be to ensure that all ants CAN change their crystals in say a couple of minutes.

3. For all roaming Robot and Featherweight.org events four frequencies could be allocated to the ants for the duration of the event. The same four frequencies would be used at every event in the future. Crystals could be made available by the event organiser.

I appreciate there are a few little hurdles to get over, like deciding what frequencies, and the issue over transmitters with single or dual conversion. But it should be a workable solution.

Any antweights who use 27Mhz could continue doing so, and those on 40megs could use the four standard issue crystals available at every event. (If they want to invested in their own set of the nominated crystals..thats their choice)

My suggestion is 40,685,785,885,& 985.

Antweight roboteers could continue using whatever frequencies they want at Antweight only events like the AWS.

Featherweight and Heavyweight roboteers would have to respect and avoid the above four frequencies in the future.

Any comments welcome.
