I bought a BIFO USB810 USB/Serial cable that was recommended by the folks at Uni_Trac for use with there sat interface. It has worked flawlessly for all comport connections. I use it with a DB9 nul modem to interface my FT-847 and my Acer laptop XP via USB and have had no issues. The Blue Computer converter cable I was trying to use before would not work. It came with driver disk for XP and I downloaded the Vista driver from there website. It works fine on my vista machine too. You might try this cable. It might solve your problems. Good luck with it.

Interesting. My problems are ALSO restricted to my USN to Serial interface. The one serial port on each computer works flawlessly.

Tim,
The USB-serial interface seems to be the weak link in almost all computer-to-radio programs I've seen. Could you tell me exactly which interface you are using with the Acer, where you bought it, and, if not plug and play, where did you get the driver?
We bought one of those little Acer notebooks but are not using it for ham radio. I thought it was a great deal for $350 and now I'm seeing them for as low as $250.

I have version 4.1, I believe it's build 1895 (it's on another computer), and it's very plainly labeled as a Beta. I presumed in deciding to download it that there could be some issue.
Here, however, there have been none - at all. It opens, runs (including Google Earth), does everything smoothly and without even the slightest problem.
As mentioned, I'm running it on an Acer Aspire One Netbook, which has an Atom processor and XP home edition.
73 to all,
Tim - N3TL -------------- Original message from Bill Dzurilla billdz.geo@yahoo.com: --------------
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?
