Flowchart of the EN55 station setup... power distribution eliminated for clarity:
I currently have 2 QRP-Labs QDXs covering 40-10m, and a QDX-M built for 160m as the rigs at EN55.
I switch between them with a DJ0ABR Transceiver selector board I built up and into a box.
That board is feeding into a Hardrock 50 amplifier with ATU, after going through a MFJ1708B-SDR switch (for my KiwiSDR2)
The Hardrock 50 goes into a Paradan antenna disconnect, which connects to a GDT, then to
75 feet of RG8-X, up to my Palomar Engineers 4:1/1:1 balun connected to a 138 ft, 3-sided horizontal loop at 34 feet high. On 160m, I'm using a full size 18 awg wire dipole with one leg bent, and only 13 feet off the ground..only connected for a day or 2 at a time temporarily right now.
When I'm not operating, the antenna feeds my KiwiSDR 2.
I have a Lenovo Tiny PC running WJST-X, Gridtracker, and Node Red. Node Red controls the amplifier and the 12V power needs.
The 12v power for the QDX, Amplifier, and some accessoriees is controlled via a Devantech ds378 relay board in a box. AC power is controlled currently by wifi switches.
