[aprssig] FREQ Object radio issues (b)

[Lynn W. Deffenbaugh (Mr)]

Spec says "Toff", not "TOFF", for a wide repeater (toff would be 
narrow).  Yes, the devil is in the details.

And the jury is still out as to whether or not Yaeus's APRS radios are 
able to tune to frequency objects without the frequency in the comments, 
so if you set these up, have a Yaesu owner give them a QSY test (note 
that it is also my understanding that the FTM-350 must be in VFO mode 
for the QSY/Tune function to work).

PS. Thanks for posting these because I wasn't flagging the OFF as 
non-compliant in APRSISCE/32.  It will in the next development release.
