Useless? Well apparently you only played with it for a little bit. I find it quite useful for all types of situations. We have bike races here in Cochise county and it is perfect for keeping track of the different groups of riders. Also nice for getting wx warnings and chatting with other hams that use it. There are plenty of things to do on APRS and the DOQRZ option is just another tool added that makes it even more versatile. Now what do you mean a waste of bandwidth? APRS uses only 1 freq in the 2m band. At least it is pretty much used by hams only unlike the waste of bandwidth called winlink. APRS is the most efficient use of the spectrum by far of any mode. Multiple uses can share the same freq all at the same time unlike voice, sstv, winlink, etc... Try getting 7 or 8 folks talking on a voice freq at the same time. I bet I can shove more information out faster than any of the modes I mentioned above so again I ask how it is a waste of bandwidth?
