I have an old Flex 3000 and I was having many strange issues. Carriers spaced all over the bands, ANF was choppy and useless, NB was useless. I noticed the guy I got it from had given me a SIIG card with a VIA chip set. I decided to find a TI chipset card and found a used card on Ebay with a TI XIO220A chip.
The change it made in the operation of the radio is amazing. All the carriers are gone. NR and ANF now work as well as NB. Waterfall is now clean without bogus carries showing up.
Although the VIA showed up as no compat issues in the info screen on the Flexradio firewire program but it indeed did have issues.
I know many people like me are still using the 3000 and 5000A so wanted to let you know what issues I was seeing and that in fact they were all caused by the firewire card.
