Yes it does but it leaves me with one last question (hopefully :-D). Something
must be wrong then if I see a qAR on the raw data feed on findu.com (APRS-IS
data) correct? Since my packets do show up with qAR on findu.com.
(For those of you that hate GPGGA type strings I am getting a HamHUD to fix that
