Time-nutters-- Aaaarrrghhh! My T-bolt died.
I have the version with the built-in power supply that requires only a +24 input. The power supply is putting out +12, -12 and +5. At least I see these voltages on the upper board on the pins of the 6-pin connector that supplies power to the main board. What puzzles me is that the main board acts as if it is not getting *any* power; the OCXO stays cold and none of the multi-pin chips on the main board seem to be getting any power as they do not show any sign of getting even the slightest bit warm. The main board is a multi- layer PC board which makes it nearly impossible to trace how the power supply voltages get to anywhere on the board. Fortunately, I have a back-up T-bolt I picked up on flea-bay and it works... at least it puts out 10 MHz and clock pulses. What is the correct Lady Heather procedure for setting up a T-bolt for best performance? I powered it up and told it to do a survey. Two displays came up; one that plots fixes on a horiz and vert axis in different colors and one that shows the tracks of all the birds passing overhead. However-- all of the color dots showing fix points are waaayyyy off at the top of the little display box. After doing fixes for a few hours it appears that most of the fixes are off screen outside the upper side of the display. It appears that I have not gone through the correct procedure to do the proper set-up to put the T-bolt into service at a new location. Any suggestions on the proper sequence of Lady Heather commands? Thanks!!
