If you go to http://aprs.fi/?call=a%2FKD8KSN-9 and view my path over the 
past three+ hours, you will see I made a trip down to Frazysburg and back 
home.  I went down, came back, shut the beacon off, and it was about 10:40a 
this morning.  I just got on APRSIS (KD8KSN-12), and I had a message that I 
sent from my mobile (KD8KSN-9 - the one I am having issues with) this 
morning *along with the response from the other station* waiting in my 
inbox.  I went out to APRS.fi, and it has me plotted down in Frazysburg at 
1620z, going 34mph.  The beacon is shut off at the radio (it is just 
monitoring a repeater), and it is sitting about 50ft from me right now – 
definitely not in Frazysburg.  I know that aprs.fi plots you at your last 
location, but according I checked it this morning and it had me back home, 
now it has me randomly in Frazysburg.  It is almost like a packet is being 
saved at a specific location and then being transmitted at a random moment.

I have had this issue over the past few days when I go into Columbus – I go 
in, come back, and about 2 hours later is suddenly plots me somewhere along 
the path I took 3 hours before, along with about 2-3 other stops along the 

One last thing regarding the message I received.  Go to 
http://aprs.fi/?c=message&call=KD8KSN-9  The “gm!” that was sent at 1248z 
this morning, along with the auto response from W8KRF-1 were the original 
messages.  The duplicate message that was sent at 1620z was sent while I was 
no where near the radio.  This was sent at the same time that aprs.fi 
plotted me back in Frazysburg.

Does anyone have ANY idea what this thing is doing?  I am running the 
FTM-350AR w/ smartbeaconing.  I have had absolutely NO issues up until this 
point. If you need clarification please email me.  I will be going out in a 
few so the path on aprs.fi with probably be erased.
