comment How do I make a SHP file from waypoints?
You are right, nevertheless the gpx folder in my unit shows several gpx files, which can be confusing, the advantage of using EasyGPS is that shows all the information living on your gps unit at once. You can even select and delete things that you do not want in your final gpx file.

comment Reprojecting between NAD27 and WGS 84 part III
I want to let you know that the online tool works for points, nevertheless they have a paid product called IRIS that could work to transform layers, not only point by point between nad 27 and other coordinate systems. This product is a spatial information visualizer with some GIS capabilities. I was fortunate to grab a copy of it and I will make some experiments with it.

comment Reprojecting between NAD27 and WGS 84 part III
The INEGI (TRANINV) on line tool works to make translations between NAD27 and ITRF92, I get 500029.111572mE, 2100624.194940 mN. The difrerence is about 3m. The article you mention has a 7 parameter transformation but for ITRF92 epoch 1988.0 and NAD27. In the thread they say there are no known parameters for transformation between ITRF and WGS84.

I get the values from earth-info.nga.mil/GandG/publications/tr8350.2/wgs84fin.pdf appendix B.6-5., es.scribd.com/doc/2618870/ArcGIS-Transformations and resources.arcgis.com/en/help/main/10.1/003r/pdf/… page 53. As you can see the parameters I mention are only valid for Mexico

comment Project from Datum Nad27 to WGS84
I know you are usin Qgis, but I checked the transformation information in ArcMap. According to this es.scribd.com/doc/2618870/ArcGIS-Transformations for ArcMap you have to use NAD27 to WGS84 transformation 2. In this document: resources.arcgis.com/en/help/main/10.1/003r/pdf/… at page 53 the parameters for ArcMap´s NAD27 to WGS84 transformation 2 are the ones I mentioned before
