I use this case.
I am able to squeeze everything I need into it for my (tr)usdx.? And by squeeze, I mean seriously cram.? I have a small battery, wire antenna, K6ARK antenna, K6ARK paddle, earbuds, K6ARK audio adapter, some cables and such.? Everything has to be placed in a very specific spot and I need to wrestle the zipper closed, which is then stretched quite taut.
The QMX is slightly smaller and needs some different bits, but it should fit just fine.
This is my go bag emergency radio, so I don't use it regularly.? But it's small, compact and holds everything I need (minus a mast of course).
Hope this helps.
