[time-nuts] Re: GPS failed

Skipp I am aware at least in the US that there is the possibility of 5G interference along with newer possible bands that 5G can use. I have read several articles in a publication called GNSS. Thats why I am using wwvb at 60 KHz. Humor intended. Regards Paul WB8TSL On Mon, Jul 11, 2022 at 8:49

[time-nuts] Re: What's the best HP OCXO for frequency counter reference?

David Great comment on power. I used to run everything 24 X 7 also including various radio sets. That was all fine when Mr. Ready Killowatt (Believe he worked at a Nuclear Power plant) was 2-3 cents a KW and the only other charge was a meter rental. But then the darn rates started going up. Now I

[time-nuts] Re: HP5065A optical package rebuild

Corby Helpful pix. Did they all fail indepently or was there some sort of failure that caused the failure. I would certainly like to know how you may have rewound the heaters. How about the exclusion area? Regards Paul WB8TSL On Mon, Jun 13, 2022 at 12:22 PM Corby Dawson via time-nuts <

[time-nuts] Re: Need help to DATUM Power Supply MPS (Type MFS Modular Frequency Systems)

Helmut. Welcome to time-nuts. Your pictures are very helpful. May I suggest the easiest possible answer? Simply supply 24 volts to the back connector. Guessing 4 amps. If the system works you just have the AC supply to figure out. Figuring out the AC supply seems reasonable as it appears from the

[time-nuts] Re: Home Brew GSPDO

Congratulations on the fun project. Well the easiest thing is to use two level comparators on the filtered DC. One for high and the other for the low trip point. Then feed a LED or a set reset flip flop so you have a memory. Unlocks are a challenge in that everything may work just fine but then a

Welcome to time-nuts Pastorino. Very nice reuse of some box. A question how big is the heat sink on the Eftratom? Or is it what came with the unit? Regards Paul WB8TSL On Tue, May 31, 2022 at 1:42 AM Pastorino G. via time-nuts < time-nuts@lists.febo.com> wrote: > Hello, this is my first post,

[time-nuts] Re: LORAN C receiver

Glenn good afternoon. Unfamiliar with that receiver. If its a location receiver for a plane or boat then it has no value as they depended on 3 sites to generate a location. Today the eLORAN tests have been pretty much single site that fakes a secondary transmitter. Things like Austrons and SRS can

Re: [time-nuts] A simple sampling DMTD

It turns out Bobs dumpster was my dumpster by a long path. I still have the sampling HP54100 1 Ghz scope and it works. Many other lucky bits to get. Best regards Paul WB8TSL On Mon, Feb 24, 2020 at 1:43 PM Bob kb8tq via time-nuts < time-nuts@lists.febo.com> wrote: > Hi > > Yup, welcome to the
