Not really. The message destination field is a fixed with in the spec format. If you don't send to a 9 character destination, it pads with spaces to 9. The reason we're sticking to 6 is that Yaesu's have an AX.25 compatibility restriction. The object name can be as long (up to 9) or short as you can make unique, but again, that will be going into an object packet that is also a fixed width of 9, so shorter object names in the message to OBJECT (or POI) won't really make the comment longer in the final packet necessarily. I'm also all for shorter, especially when targeting spin-n-click radio interfaces. Lynn (D) - KJ4ERJ - Author of APRSISCE for Windows Mobile and Win32 On 2/21/2012 4:59 PM, Stephen H.
