Sounds like the GPS receiver is hosed. I think there are two different receivers used in the 58503a, unfortunately I'm away from my lab, otherwise I could check mine. It is a standard part, and may be available on the surplus market. Before replacing, I'd check the usual suspects, power

[time-nuts] Frequency doubler 5/10 and distribution amplifier for Lucent KS-24361

2015-01-02 Thread Gerhard Hoffmann
Hi, all, over the Christmas season, I have designed and built a frequency doubler from 5 to 10 MHz and a distribution amplifier for the Lucent KS-24361. A preliminary writeup is under http://www.hoffmann-hochfrequenz.de/downloads/DoubDist.pdf It features 4 or 5 10 MHz 10 dBm outputs
