I have read a few reports saying the VX-8GR doesn't pick up the GPS signal while inside of a house - well, neither does my Garmin eTrex Legend HCx, Garmin 60Cx, or my cell phone. It doesn't work as a full featured TNC, does not support QSY in beacons, etc. What it does to is APRS and it does it fairly well. As an example, on my trip from Ohio to Maryland I had both a OT2m tracker running with my Kenwood FT-V71a running 25 watts and the VX-8GR running 5 watts sitting on the dash. The results were about what I expected:
k8esr-7 (vx-8gr): 31 packets received
k8esr-9 (OT2m with TM-v71a): 62 packets received
I had low expectations for the handheld and I didn't think I would even get half of the received packets using the VX-8GR without and outside antenna and more power.
If you are looking for a good HT for APRS check out the Yaesu VX-8GR especially if you do not wish to pay $200+ more for the newer Yaesu FT-1DR.
This was not meant to be a review of the VX-8GR because there are already many reviews that you can google as well as a few un-boxings and reviews on YouTube.
If you are looking for a comparison of APRS HTs take a look one of these links

APRS Handies head to head
Both sites do a fairly good head to head comparison of the Yaesu VX-8GR and the Kenwood TH-72A.
