I've been working on this project for over a year now. It's still in the "breadboard" stage and details are constantly changing, but despite the rough appearances it works well and is very robust. It stuffs into a backpack and allows operation on HF, 6m 2m and 70cms with minimal set up time in the field. Antenna connections on the top enable fitting an antenna direct to the frame if I want to leave the set in the backpack (I have a set of counterpoise wires of varying lengths for when I do that), or to run a coax to a remote antenna. In the field I tend to use an MP1 antenna (with which I have had some superb DX contacts) for HF, and I have small portable homebrew antenna in the bag for VHF bands too. Power comes from a small 7 amp battery which generally gives me 2 or 3 hours' life if I transmit at 50w, or all day if I run at about 20w or less. Using this set up via the MP1 on a holiday in Scotland I have had QSOs as far away as Brazil on 50w.

Good looking setup. I am working along the same lines for my PM station. I have an Alinco DX70TH which should work well. I will post a picture when I get a little further along.

That looks like it's coming along well.

Here is a link to mine which I started in 2013 and am still improving! - FT-857 Portable Manpack | M0LMK (http://www.m0lmk.co.uk/2013/11/13/ft-857-portable-manpack/)

I do like the FT857, great radio, however, since getting this call sign in 2011 I chose to operate QRP and I adore the FT817ND so much that I have two of them!

SOME of my portable kit.... (http://www.arpoc.org/show-off-your-station/90-portable-kit.html)

That looks like a nice kit Chris.

Can you make a new post in this forum (http://www.arpoc.org/forum11/) so that others can comment without derailing this thread? I'll link your post above to it when your'e done. :)
