Hello all

The program for the month will be on echo link.
We look forward to seeing you there.
We would like to invite you to attend the August meeting of the Blue Ridge Amateur Radio Society.
Location:
American Red Cross
940 Grove Rd, Greenville, SC 29605
Meeting starts at 1900 hours.
Our program will be given by Alex Norwood as a follow up of last meetings program on DMR.
We will also be discussing next years Hamfest along with Field day.
We look forward to seeing you there.
At the July meeting, Danny KN4BEM gave a presentation on DMR.
The presentation is attached to this post. If you have questions, feel free to comment below or email KN4BEM@ARRL.net.
DMR presentationI’ve been in need of a good way to mount my growing collection of Raspberry Pis (rpi) and to power them from a convenient power supply. Wall warts are notorious for not supplying the correct voltage or meeting the right amperage requirements. To that end, this article was begun.
A bit about my needs, I have a rpi that includes additional hardware in the form of what is called a “hat” and also a SATA hard drive. This hat fits on top of the expansion header on the rpi, and provides additional functionality. For this article, I will be using the club repeater antenna monitor system as an example.
The initial setup consisted of a rpi, a Pi-plates DAQCplate (for Analog to Digital Conversion), and a SATA to USB board for the hard drive. The system runs from a 5Vdc/4A AC/DC power supply (wall wart). During testing under load, the power supply regularly dropped to 4.8Vdc. The rpi requires a voltage between 4.8 and 5.2Vdc. Below 4.8Vdc, the whole system becomes unstable, with possible loss of data, poor A/D acquisition, and a whole host of other issues.
After a fair amount of searching, I came upon a hopefully better approach to the power supply issue, in the form of the Bitscope Blade Uno Pi (BB01). This has a few useful features beginning with a wide range (9 to 48Vdc) power supply which outputs 5Vdc at 3A (4A peak). This allows me to use any of my ham radio power supplies and/or battery systems to power everything. Additional features of the BB01 include an extra 5Vdc power header, and dual USB jacks to power other devices.
More to come soon!
