I'm thinking of putting together a Pelican-style case sized & fitted to hold a Flex-6300, power supply, Maestro, FlexControl, Desk Microphone, a small router, a Rigrunner-type power distribution panel and cables.
Box "B" case would hold coax, grounding straps/clamps/mini-rods, an antenna switch (manual) and a selection of my usual wire antennas. Also spare bits and tools in this box.
Softpacks would carry my SteppIR CrankIR and its stand, or the ex-NATO HF conical I also sometimes use. Eventually I could see putting the Softpacks into a larger gun-case shaped Pelican-Style Case for shipping, but those cases are heavier than I would care to lug about if the Softpacks can do the needed duty.
