Wow, Tom,

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!

Thank you,

Pat N8PK

Hi guys, We have about three weeks until our local AMSAT meeting and space seminar. Here is my status report

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).
