Thanks for the replies. I have been playing with Sat Track all day, using a Lenovo T61 laptop running Windows XP Pro connected to an IC-7000, in Single Radio mode. It appears that there are issues with Sat Track even with this OS. Unlike with Vista, everything opens quickly and it never uses even close to 100% of memory.
However, the program immediately freezes and becomes non-responsive if I click on Google Earth. More importantly, it sometimes becomes non-responsive when I click on TX, and the radio stays on transmit until I close the program. Also, sometimes the frequencies get mixed up. It will transmit on the downlink frequency or receive on the uplink frequency.
Is the Sat Track beta "technology preview" still buggy or am I doing something wrong?
