Good idea! A user could specify, say 3 satellites, with orbital elements. Without internet access, ?there is no way to change these elements as orbits are corrected though, unless one edits them an

Another possible feature would be satellite rise and set times if there is room in the mcu for the tables.

Thanks for publishing this nice project, I'll have to put it on my to-do list! :-) Karl Jan - LA3FY tor. 30. sep. 2021 kl. 08:04 skrev Sverre Holm <svholm54@...>:

My Arduino GPS Clock is now published. It shows GPS info such as UTC time and locator, also local time with daylight saving for a user-configurable timezone, solar and lunar position and rise/set

Hi Halden, I use the AR-60A for the Tektronix DC503-A frequency counter (instead of its 10 MHz oscillator) and use the Datum LPRO-101 for the R&S SME03 RF generator. -- Cheers Attilio

Hi Attilio, That looks consistent with my understanding.? The temperature has to be managed to prevent the unit from damaging itself with its heat.? I wish I had a manual for mine, but that's what I

Hi Halden, If it can help, here is what the Datum LPRO-101 manual reports about the heatsink: "A heat sink or mounting base plate is required to keep the baseplate temperature under 70°C. Internal

Hi Halden, it is also my concern. I probably misunderstood what is written on the manual of the Datum LPRO-101, I have to reread it. -- Cheers Attilio

Hi Attilio, If I understand correctly, rubidium oscillators aren't sensitive to changes in ambient temperature, and that's why they're so useful.? My concern is components failing due to getting too

Hi Halden, thanks for the information, I read in my Datum LPRO-101 manual that a 2 ° C / W heatsink should be placed on its bottom plate. If I understand correctly it should serve to stabilize the

Hi Attilio, I bought a surplus rubidium oscillator of a different brand.? It takes a few minutes for its initial warm-up before it gives its output signal.? But once it does, that signal's frequency

Thanks Erik, I'll try. -- Cheers Attilio

Maybe a good place to ask this question would be the projects group on the eevblog forum: https://www.eevblog.com/forum/projects/ -- HBTE Files section: /g/HBTE/files Erik, PD0EK

Hello to all, I bought used an AR-60A (AccuBeat) and a Datum LPRO (I think it's from Efratom) and they both work. I have no experience with these Rubidium frequency standards and would like

Thanks DuWayne, This build is going to be dead bug style, but I will doubtless be using the 8307 again. Is your pcb for the dip package or the smd version? 73 Ellis G7SAI

Post it in any case, someone else in the future may find it useful.

I have used the 8307 in several projects, and found it to be an extremely sensitive device.? To get a good noise floor you really should shield the? 8307 stage. I have etched my own double sided

Thanks Erik, I'll stick with keeping the AD8307 on its own shielded daughterboard. I have some feedthrough capacitors so I may use some of them to keep as much noise out of the detector. 73 de Ellis
