The Thunderbolt arrived today. Thanks again to all involved. However, it looks like my PSU is faulty.
I carefully cut the outer on the cable, splayed out the coloured inner connectors, so as to avoid short circuits, and noticed that colours of the insulation on the cable cores did not match the colour code given at http://www.leapsecond.com/pages/tbolt/power.htm No problem, I have a multi-meter and was trained as an electrical engineer so I should be able to sort out what was going on. On plugging in a lead there was a slight 'buzz' and, on checking the outputs, no DC volts. Checking the lead showed no AC volts. So, I opened the plug and checked the fuse, a 3 Amp type - too big for the unit output really, but shouldn't have blown... Changing the fuse for a 1 amp type, and plugging back in showed no output voltage again. Checked the business end of the lead and there's AC volts still there. I'm guessing, from experience of these PSUs in the past, that there's a fuse inside the unit which has also blown. If so, I guess I have a faulty PSU? Ah well, a trip to the local PC Store for a +12v/-12v, +5 Volt PSU I guess. Also, I see that the antenna socket on the Thunderbolt is an F-type. Someone has thoughtfully provided an F-Type to BNC adapter. However, the plug on the Motorola GPS antenna is an SMA type. Ah well, I can make a lead which should work instead. :-) Dave _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
