I did this very thing Friday morning using a GPS enabled Android tablet
with a free GPS compass application. The GPS app shows true north, so
no corrections for magnetic north needed, and no problem with the tower
interacting magnetically with a compass.
Can't remember the name of the Android app. N4GU showed it to us
Thursday night at club meeting, and W0UCE loaded it up for Friday
morning's antenna alignment.
Seems like the iPhone must be GPS enabled - probably has a similar app.
Or drop a note to N4GU or W0UCE for the name of the Android app.
