Hello All, Today, I came in possession of a Mastr II low band receiver on 33mhz for a 10 meter project that I'm working on. What caught my eye right away on this particular receiver was the IFAS board. This board looked dramatically different from all those I have seen before. There were numerous 14 pin IC's, only one audio device mounted on the side, and no transformer. The part number on this board is 19D902492G2 Rev F.
I'm wondering if anyone has any experience in the use of this board as pertains to squelch action. Were there any improvements or anything that might have made things worse? I know pretty much what to expect with the "other" (maybe older?) style IFAS boards but this one is new to me. Any information would be greatly appreciated. Thanks! Adam N2ACF
