This is a new radio and has not even had the cover off - yet.

I just read a very good page by N8UR on this exact thing - I was not aware 
of this for FM.  While I have played around with a TNC some in the past, it 
was on HF using SSB for the WinLink system (yes, I know a dirty word, but it 
was nice getting email while away from port).  Heck, I even passed some H&W 
msgs via email while anchored during Ivan for some of the other boats - and 
kept my family aware of my status during the hurricane.  They knew as long 
as I was able to send emails via ham radio, I was still ok and floating.

 Yep, while testing I will beacon manually in that manner, but usually it's 
while riding down the road, so there are changes in position.

We ALL do *funny" stuff like that - thanks for sharing {grinning}

I am VERY happy to say this whole bunch is MUCH more gentle and 
understanding than some of the folks over on the QRZ and eham forums.

As I've said before, you folks keep up the good work so the rest of us 
simple folk can enjoy this interesting aspect of ham radio.  We appreciate 
your work.
