Re: [time-nuts] LORAN C simulator operational
Back from a trip and have had a chance to clean up the software for the LORAN C simulator. So do people generally just attach that to this thread. Say a schematic and basic program. Then thats it??? The simulators very stable and at this point the Austron 2100F goes from acquire to track in about 2 minutes. With the first readout at 1.1 e-11 between the two references that I am using. I am using a gri of 6 though others can be used. Signal level 48 which is quite strong. By the way schematic wise I suspect final output a gif. Any particular free schematic software people use. I am comfortable with visio so may just use that. Reagrds On Tue, Dec 8, 2009 at 2:48 PM, paul swed paulsw...@gmail.com wrote: A few weeks back I started a discussion on the demise of LORAN C.

Hi Paul: Glad to hear it's working! Free schematic software at: http://www.expresspcb.com/ They also have PCB layout that's tied to the schematic and very reasonable prices for making boards.

Re: [time-nuts] LORAN C simulator operational
I just received this good news from Poul-Henning Kamp: = If you want the GRIs in microseconds, add a zero: 67310, 74990, 70010 and 90070 My 2100F had no issues with them. = That's great news for me, if the signal is strong enough. -John = Thanks Peter, I will hope that it evolves to eloran but for .0002% of the budget we will shut it down. That said if you want to use your Austrons in North America I have an answer for you. There is the suggestion of at least on the eastcoast using Europe. But thats skywave and my research indicates thats about 1 X e-10. Also the fact that the Europe chains use a finer GRI rate. Hard to say if the Austrons will work.

Re: [time-nuts] LORAN C simulator operational
Hmmm I tried that on my 2100f to see if I could get skywave Europe LORAN. May have to try it again. Thanks for the tip. On Tue, Dec 8, 2009 at 6:52 PM, J.

Re: [time-nuts] LORAN C simulator operational
Anyone know about the LORAN-C Monitor, part of the Austron System 5000? Anyone want it? Two digital displays and a rectangular scope.

Sounds neat if no one else is interested I would be. But I may find out its 200 lbs. :-) On Tue, Dec 8, 2009 at 8:38 PM, Bill Hawkins b...@iaxs.net wrote: Anyone know about the LORAN-C Monitor, part of the Austron System 5000? Anyone want it?
