I've been using a TinyTrack attached to a Yaesu FT-857 on 300 baud 30M HF APRS 
in my mobile setup for this .  The primary mode of the TT3 beacons the usual 
red car icon.  I have the secondary mode set to beacon the Field Day/Tent icon 
and the status field  "NPOTA - National Parks On The Air!".  This quite 
consistently finds it way to the APRS-IS from pretty much anywhere in North 

My undertaking has been to do NPOTA on live SSTV.  What better location for 
SSTV "LiveCAM" shots that the National Parks?   I will be beta-testing my next 
configuration from Sleeping Bear Lakeshore on the 7th of May after the 
Cadillac, MI hamfest.

My mobile setup now consists of three radios. The Kenwood D700 on 2M and 450, 
and two Yaesu FT-857s.  One '857 lives permanently on 30 meters connected to a 
30M Hamstick for HF APRS.  The other is on all bands 80-thru-6, other than 30M, 
with an auto-tuning W6HIQ screwdriver ant for mobile live SSTV.  Both HF mobile 
antennas are so narrow band that I have not had any interference or desense 
issues running both at the same time.   Even though the two HF whips are only 
about 3 feet apart.
