One operating position is fully functional. The shack has 4 operating positions and each position can choose any available transmit antenna through a 100 kW Strip Line Matrix Switch remotely controlled.
The remaining tasks are to install panels at each operating position to plug in bandpass filters, install wiring for remote antenna switches and power combiners, install computers at positions C and D, wire up PTT control to the Strip Line Matrix switch (to prevent the possibility of hot-switching) and build an indicator panel for the switch.
I will now concentrate on the farm work until autumn before continuing with the project.
The open wire feeders are getting rather slack. This causes the wires to twist together during high winds. I had noticed a slightly higher SWR and some scratching noises while receiving on the USA Rhombic.
I had to examine the entire run of the antenna feeder and the antenna itself. Looking up into the bright sky is rather difficult for me due to the condition of my left eye after the accident, but with a good pair of binoculars it only took me about one hour to find and correct the problem.
I guess some maintenance is called for before winter…
