[aprssig] D710 APRS Non-printables

There have been several D710s running around recently with non-printable 
characters following the QSY frequency.  I have contacted several of 
these owners and the common thread in their experience was the use of RT 
Systems Software to program their radios.  I just received this 
confirmation from Dan White W5DNT that RTS is the root of the issue as 
well as a solution to the problem.

PS.  I've recently seen the following stations displaying this problem.  
You can use the raw packets display at aprs.fi if you want to see the 

K8WHB-1, KB1UNY-9, KK4AUJ-9, VE6TDX-9, KD4PCU-7, AC0CO-9

I called RTS and they said the last update fixed this, however it 
required the old text be re-entered and re-saved. This requirement was 
not communicated to users apparently. Problem had to do with how they 
were using <0xff> to take up "blank spaces of text" in radio. I re-did 
the settings, problem gone. Look at W5DNT-9, packets sent at 1640z 
minutes ago. Thanks for pointing this out to me (and RTS!)
