Dave,

I have used the original RadioSky AtoDMax circuit on my Lehman for about 3
years.  I use the PSN preamp filter circuit with power hardwired from the PC
supply.  I have modified EMON to collect data in PSN format files from the
Maxim converter.  It all works quite well other than there is no stable time
reference.  I've experimented with several programs such as Right Time and
they will give a fairly stable clock but I have not been able to get a
combination of stable time running with EMON.  The date will not roll over
at best or the machine will lock at midnight.  The same result has occurred
on 2 different PCs.  If doing over I would power the system some other way
simply for convenience of changing computer and also for mobility as I have
loaned the system to the high school and a local college on several
occasions.

> Hi Everyone,
>
> I have new releases of WinQuake and WinPlotGPS available on my web site
here
> http://www.seismicnet.com/wqdocs/wqbeta.html and
> http://www.seismicnet.com/winplotgps/.
>
> WinQuake;
> The only new feature in this release is the ability to read MINISEED
> volumes. I added this feature so I could look at event files from the IRIS
> Bud system. See this link
> http://www.iris.washington.edu/bud_stuff/dmc/bud_monitor.html for a
starting
> point to download MINISEED files from their system. The problem with
> MINISEED files is they only contain the raw data. Information like sensor
> location, sensor type etc are not part of the data file. When processing
> MINISEED files, it is assumed you have the stationary information like
> station latitude and longitude in a dataless SEED file (or some other
> format) that can be used to fill in the missing data. When you open a
> MINISEED file, WinQuake will try and find a dataless SEED file on the
system
> so it can use it to fill in the missing data. See the documentation at the
> bottom of the beta release web page for more information.
>
> WinPlotGPS;
> The program can now act as a TCP/IP GPS data server or client. I added
this
> feature because I thought it would be "cool" to do it. I'm not sure how
> practical this new feature is, but with it you can send the data from the
> GPS receiver over the Internet (or local LAN) to another copy of
WinPlotGPS.
> See the WinPlotGPS documentation for more information. I hope to do the
same
> type of thing to my WinSDR datalogger. This way WinSDR users can remotely
> monitor their system using a TCP/IP connection.
>
> I also fixed a problem with the Reset GPS receiver command. Now when you
use
> this command with a ONCORE receiver (it has no effect on other GPS
> receivers) the receiver will be reset back to the factory default
settings.

> Enjoy....
