A normal position report looked like this.

A few minutes ago I noticed this position report.

Notice that the first character of my call is dropped and the
path has changed and there is a strange character at the end.

I wonder if W5YD-5, an xastir instance, could have replayed it
back to the APRS-IS somehow? The path does not make any sense. Or
is W1GG-1, an aprx igate, bugging somehow and transmitting it to
RF, it's comment says it's a TX igate? <a class="moz-txt-link-freetext" href="http://aprs.fi/info/W1GG-1">http://aprs.fi/info/W1GG-1</a>
