Some updates. After browsing carefully on ebay, found a reputable seller for new 1GC1-4210s. A few days later and DHL drops off the parts from Hong Kong. They look brand new, still in the tape and no tinned leads/pads, so I'm inclined to believe these are new parts. Swapped them out on the A6 Frac-N board and the sub 3.2 GHz lowband is working great now!
Unfortunately, this didn't solve the 707 Sweep Phase Detector error I'm still seeing during the complete self test.?
I'm also seeing a new error message "310: Hardware communication error during ramp sweep".?
?If the sweep phase detector circuit is painfully obvious on the Frac-N board pictures, feel free to spitball any ideas...
