Yaesu VX-8GR APRS Backpack Portable Performance

At the 2013 Hamvention I picked up a Yaesu VX-8GR which unfortunately Yaesu discontinued when they released the FT-1DR for their System Fusion concept. In 2015 I still own the VX-8GR and I decided to use it for my Saturday trip. My primary HT is a Kenwood TH-F6A and to keeps things simple I decided to make my APRS backpack portable. This was a simple build consisting of a backpack, a 3 foot extension cable SMA male to BNC male, BNC female to SMA female adaptor, and tie wraps.

I attached the stock antenna to the backpack and ran the extension cable to the side pocket. A nice quick "build" so to speak. With all of the APRS traffic at Hamvention I was not entirely sure how well this was going to work. I set the HT to transmit at 3 minute intervals and let it go for the day. From 9 AM until about 2 PM 39 packets were picked up and available to map in APRS-IS.

Yet again, I am impressed with how well this little radio performs in a crowded environment. The GPS has sufficient sensitivity to provide some position packets from within Hara Arena. As you can see, we did a decent job making our way through the flea market on Saturday.

So, if you are looking for a good HT with great APRS battery performance (blows the Kenwood TH-D72A away on battery life) I still highly recommend the VX-8GR. These radios are no longer in production so you'd have to pick it up on Ebay or in a flea market. If you do buy one I don't think you will be disappointed.
