Not exactly... v1.2 added an active filter. In v1.1 there was a space there for memory expansion that was never used. The two aren't related and there's no way to add the active filter to the v1.1 or v1.0 board. If you're getting bad RX performance on an older board, the first thing to try is to heat up all of the solder joints one by one around the 2211 chip, especially including the capacitors along the left side. After that, clean it thoroughly with a toothbrush and isopropyl alcohol and dry it. About 75% of the time that'll significantly improve the RX performance. Of course, you're always welcome to send it back in for repair or replacement as needed, no charge. Just include your order number if you've got it and a note about the problem and send it to: Argent Data Systems 543 W. Betteravia Rd. Ste H Santa Maria, CA 93455 Scott
