Volunteering Support: 2016 BMW Dallas Marathon

I got to volunteer as a shadow to the Relay Coordinator supporting the 2016 BMW Dallas Marathon.  I needed a higher power radio setup that I could temporally install in a late model Tahoe complete with APRS support.  I setup a Yaesu 400DR, and ran APRS on VFO-B.  Mounting the raido on a 11X17 cutting board allowed me to temporally hang the entire setup off the back of the driver or passenger seat with a 5/8 wave mag-mounted antenna for “portable mobile” use.   This setup was very easy to setup in under 2min time and if needed would have been able to move to another vehicle or operate from fixed location for an extended period of time using the 12 volt 10Ahr battery.   The control head had a RAM-Mount ball and could be either mounted to the cutting board or on a window RAM-Ball mount for easy viewing.   I extended the mic connection with a 15” length of flat-satin cable with 6 pin RJ-12 connectors straight thru.  The setup worked really well and I ran it for over 7hours.  Looking forward to next year.

2.4GHz Custom Antenna Bracket For AREDN Mesh Base

Some where along the way I lost the mounting bracket for my TPLink TL-ANT2412D antenna I had purchased for a Ubiquiti Bullet M2 to be converted to AREDN Mesh to be used as my base node at the QTH.  So I decided to fabricate one that I can use in the field for testing and later on for mounting to my house.
