I am highly challenged to pare down my pack up for QRP portable. However, I think this pack will help. It was a good deal from EBay from seller 2010joeyc ALICE-LARGE-RUCKSACK-FRAME-LC-1-US-MILITARY-SURPLUS $29.99 free shipping. I have of course more than I need as pictured but it has most of my small QRP radios, tuners, antennas and so forth in it for my Christmas trip. I also found that it will work great for pedestrian mobile. More on that later. I got the idea of the pack from the Amateur Radio Pedestrian Mobile Handbook.
