GPS for time and Maidenhead for port ops

 

Hi all,

I'm interested in taking a Bitx40 and/or uBitX for portable operations, particularly for park activations.
One idea that strikes is the potential to use a GPS receiver with the Raduino to display time (as UTC or local) and the lat/long of the port site, or as Maidenhead.
My question to the group - is this feasible/practical to do it all?
My Arduino knowledge is nil but, if this was practical then I have an interesting learning curve.

I'd be interested to learn thoughts from the group.

And discipline the frequency while we're at it!
 

The QRP-Labs Ultimate3S has that capability (GPS integration, Maidenhead, time, freq) and it's got an Arduino in there.? It's at least possible.

Peter:

This has already been more or less accomplished by Hans Summers and a slew
of others. See the QRPLabs website for more information.

The first thing to consider is what GPS unit you are going to use. There are a lot of them
and they vary all over the map with regard to specs. However, they all conform to the
GPS transmission. Which is the second thing to do...see what that is exactly.

Then work out a design that uses software to display what you want. The major difference
among hams is that the GPS is also used to condition and calibrate the transmission frequency
of a DDS controlled rig (as noted by Arvo).

Yes, it is easily possible and there is a lot of information around about doing just what
you want to do. Google it; you will be pleasantly surprised.

John and others,

Thanks for your replies and comments.

These demonstrate that it is feasible and possible. Now, I need to do some research/homework and bring it all together. If you like, I¡¯ll report it here and get feedback from the brains trust :-)

Seasons greetings to all.

Peter,?

GPS frequency discipline, time, and Maidenhead grid square has already been done for the Radino/BITX40. The sketch is located in the groups file section. Do a search on GPS.? </g/BITX20/filessearch?q=gps>
 

Thanks, Gene, and I¡¯ve found the files - it looks great and exactly what I was looking tor.
