That looks like an EXCELLENT manpack. I've operated only older, legacy manpacks and other mil HF gear, once-upon-a-time, when I was in that "business". The new generations of manpack radios are simply amazing with auto-linking, data, built-in CRYPTO, spread spectrum on some models, usually fast-hoppers and etc.
Manpacks are fun for some hams and the international appeal of the HFpack group shows that there is a niche' market for them. To compare mil manpacks with Elecraft however, seems an 'cocoanut -v- oranges' argument: both hang from trees - yes, but very different. KX3 was never designed to be competition for a military manpack, because it's not servicing that market. Now, if a person DOES need or want
a portable, channelized radio transceiver capable of operation in jungle, at sea in extreme temperature/humidity and is designed to take a great deal of physical abuse yet to keep working, then yes - full mil-spec manpacks are designed for that. CODAN, BARRET, HARRIS et al have a mil/para-mil/NGO market focus which hams like you enjoy - cool!
I don't speak for Elecraft, but it's clear that the KX1 & KX3 are not even remotely designed for that market - and never intended to be. The cost, weight, size and current consumption etc. for manpacks are generally considered excessive for most hams doing civilian/recreational backpacking, for example. Paul - W0RW/pm out wandering the Rockie Mountains with one of several military manpacks is a delightful exception, who I have talked with a few times, usually in CW while he is slowly being covered in snow during in howling winds...
Looking at the CODAN spec-sheet, the weight listed with one 8 A/H battery was just over 10.3 pounds, to which must be added the essential mil-spec accessories for actual operation like handset - or phones, key & antenna(s) . We're probably beginning the day with 13-15 pounds of radio gear, not counting the ability to recharge in the field. That's very light compared
to what I carried decades ago as a soldier, but in an entirely different Size, Weight and Power class from what casual ham hikers and SOTA guys are likely to carry in addition to their backpacking gear for fun.
I'd love to hear more about your CODAN manpack, how you use it and perhaps some of the design features and how they integrate into ham use. CW filtering informaiton was lacking in the spec sheet I saw, so if you could discuss your experiences with that, it would be helpful. Your preferred antenna types for pedestrian as well as for camp are also something I am curious about. In decades of carrying HF radios, I still prefer the basic dipole, high and in the clear for all but easy NVIS shots, though a half-square run from the ATU post against a counterpoise wire has helped me much on long-haul/low take-off angle shots in times past. I never
did talking while walking until I did this for fun as a civilian. As a civilian, it was enjoyable mild-exercise while hamming or when car camping. I did exactly ONE civilian backpack trip with an old PRC-74 and spares in my rucksack -ONE. I was a tough-guy back then. These days, to be perfectly honest, I would not even attempt that, so I have my light weight, small, 'Up-Armored' KX1 instead.

Ps. I always
prefer the best, most selective receiver I can have with me.
