Flowchart of the EN55 station setup... power distribution eliminated for clarity:
I currently have 2 QRP-Labs QDXs covering 80-10m, 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 a DX-World PCB antenna switch.
During the day, this goes to my 40m loop, 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.
At night, the antenna is automatically switched to an Inverted Vee that's 56 feet high at the center and about 20 feet high at the ends, 133 feet long with 2 loading coils per side. This transmits on 160m, 80m and 40m, and is available from Hy-Power Antennas. I have about 60 feet of RG-8X going up to the dipole, and another 235 feet of RG-6 75ohm from there.
When I'm not operating, the antennas feed 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.
