I have a thunderbolt up and running since last week Friday. I'm doing this for a calibration source at work, eventually we will have two antennas, feedlines, and thunderbolts, so that we can have one fail and keep operating, but for the moment I just have the one receiver. Both antennas are mounted underneath a large skylight, as high as we can get them. I realize it's a compromise, but getting signals out to the roof will be a problem so I'm trying to work it without taking the feedlines through the roof if possible.
I've done the 48 hour survey, but my signal plot shows a big circular shaped mouse bite on the north side. I'm showing no signal up through 70 degrees at north, 30 degrees from NE around to NW. How badly will this impact me? Temperature: My thunderbolt always reports -55C which can't possibly be right. :) Is this some configuration in Lady Heather, or is something broken? Otherwise, things are looking pretty good, I'm showing an average error of about 70ppt. I'm working my way through learning Lady Heather, there's a lot displayed there that I'm a bit fuzzy on, but in the end my main concern is that my 10 MHz output is as accurate as possible in the short term. Our calibration cycle will take about 4 seconds to run, and I need <=1PPM error on the calibrated device. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
