Re: [time-nuts] [timenuts] GPS L1 chokering antenna

Hi there, something about the power supply. If it's an older Leica choke ring antenna, it uses an AeroAntenna antenna element. Perhaps there is still a label on the lower side of the choke ring. L1L2 antennas had the part number AT2775-..., L1 had been AT575-... The power supply is coded there.

[time-nuts] Solartron 7150plus DMM Failure

Hi All Apologies to any who may receive multiple copies of this but I thought it worth sending to those lists where I've previously seen mention of this meter. I have now had two identical failures of Schaffner filtered mains sockets on ex-mil 7150plus DMMs, although I'm not suggesting

Hi, A fellow amateur and I have just put together the GPS-based frequency reference published in the Every day Practical Electronics issue of April/May 2009 and are both experiencing the same problem. The type-3 phase comparator of the 74HC4046 has both 1-pps and 50kHz DC-coupled inputs designed
