Maybe this belongs in software, but it refers specifically to the Uniden Bearcat BCD396XT and BCD996XT under Butel ARC XT Pro. Since I already have both of those scanners, I already have the software, and I have a new Windows 7 desktop computer, I was looking at getting a serial port card since my USB to serial port adapter works for my Yaesu ham radio, but not the Butel software. Anyway, as I look online for serial port cards, I see that dual serial port cards are very reasonably priced. If I were to buy that and install it in my Gateway computer, can I run twin sessions of Butel side by side? I would probably use the BCD396XT to scan my local trunked system and then use the BCD996XT to search or something along those lines. Maybe this is over the top or maybe there are some other cconsiderations that I am unaware of.
