Those are simply amazing!
Yes, please DO bring the hardware demos, and I
will make sure you have a presenter's slot or
two as well!
Oh, let me know if you need anything other
than standard 120V AC to make it happen.
I will bring an agile 2m handheld too!

In case you would be interested, I have a new project in the worksthat enables a low-cost, accurate computer controlled antennapositioner. This is NOT another computer interfacethat uses potentiometers inside the rotor --- all control is digital. I'm getting about 1° accuracy in both az & el, and it is quite suitable for small (~1m) dishes and/or small yagis. Not sure of the final costs yet, but a 2-axis rotor system with controller should cost <$250.
Also, I think we will be in the position to demonstrate a functioning bench-board prototype of the Suitsat-2 SDX transponder on the air. People should be prepared to TX on 70 cm (435.9) & RX on 2M (either 144.35 or 435.90 TBD).
