Fellow Time-Tickers,     My 'old faithful' Spectracom/Orolia/Safran 9383 finally bit the dust last week. A little hunting on Ebay turned up a decent deal on its successor, the 9483.     After verifying good basic operation, of course, I had to open it up for a physical exam. Doing so, I'm reminded of why I like Spectracom hardware (at least the later series): Fairly easy to do hacks and mods, and Safran tech support is very easy-going about answering questions. My plans include:     --Retrofit the unit for 48VDC operation (there's an unpopulated spot for an eighth-brick DC/DC converter on the mainboard).     --Upgrade the GPS receiver from the original Trimble to the Ublox M8T (Found what looks like a drop-in replacement module on Ebay).     --Bring the unit's operating software up to the current level (6.00).     --(Optional): Design a dual DC operation option, switchable for either 12V or 48V input.     With that out of the way... Are there any other 9483 owners on the list, preferably who have a unit already equipped for DC power operation? If so, a photo of the innards featuring the DC/DC block would be most helpful.     And -- If any other owners of these units want me to investigate something specific, during my upgrade efforts, just ask!     Thanks much. -- Bruce Lane, ARS KC7GR, kyrrin@bluefeathertech.com "Quando Omni Flunkus Moritati" (Red Green)
