Thanks. Unfortunate. But I would guess it has to be old to get into the parts. Again with todays technology. I might see this as a preamp mixer 1.5 GHZ pll... Most likely some chip has all of it but is so small the eyes fingers and solder iron will be a challenge. Thats why the old odetics gpsstar was nice. Real parts. ;-)
