NW Digital Radio DRAWS in its Correct Case

The K9ZW #1 NW Digital Radio DRAWS is in its correct case.

Started putting my ARRL email on gear in case we get separated.

I’ve started into labeling ports on my equipment in an effort to improve “self-documentation” of gear. Why have to scramble later to online or paper documentation to confirm what voltage and polarity is required? Or whether the Right/Left port naming is by looking “out” from the ports or “looking inwards” at them?

Upper L-R – GPS, Left Radio, Right Radio then the Lower L-R – 5vdc, HDMI 1 & 2, Audio

NW Digital DRAWS – Build Part 1

Building a Portable Digital HF station for use in various activations I have planned for summer/fall 2021. Hope to have the DRAWS/RADIO set up and running before this summer.  I am NOT going to drag a FlexRadio Flex-6000 to some of the places I hope to operate from.

On the digital side I am using a Raspberry Pi (4B) with a specialized add-on bit of hardware, the North West Digital Radio DRAWS that will add a GPS/on-board clock and the necessary interfaces.

Initial intention is to us a SGC-2020 transceiver, but I may drag a TenTec Jupiter to my activations instead.  I will use a keyboard and mouse to control the actual digital software for the activations, WSJT or perhaps fldigi.

The DRAWS is a neat bit of kit that should streamline my station and reduce the component count. That said it is as best semi-documented and a bit of a work in process intended for those willing to roll their sleeves up to get it configured, wired and going. Not very plug-n-play at all.

Raspberry Pi HAT = Raspberry Pi extension board, both because it sits like a “hat” on top of the Raspberry Pi microcomputer and as the original meaning apparently was “Hardware Attached on Top”  https://github.com/raspberrypi/hats/blob/master/README.md

A bit about the DRAWS lifted from the NWDR website:
