It’s been used portable and usually ends up being thrown in a bag with the ATU, battery and other parts. I decided it was time to show it some respect and create a military inspired manpack to keep it safe and secure.

After searching youtube for some ideas, I settled on making a sort of exoskeleton frame to fit the FT-857, LDG Z-11Pro 11 and battery inside. I decided to make the basic frame from 15mm copper water pipe because I had a few sections laying around and just needed a few fittings. I also wanted my manpack to be contained inside a backpack for protection and easy of transport. pugly backpackI like to operate on HF from the local beach so having something that I could just throw on my back an go is also a bonus.nike sfs backpack review Keeping with the military theme, a visit to the local surplus store yielded a suitable backpack with a single large pocket and 2 smaller side pockets. vamoose backpack

It also has some molle loops to I can easily add additional pockets if needed. I measured the internal dimensions of the main pocket and used AutoCAD to design a frame to fit inside. I decided to make the frame from 15mm copper water pipe as I had some spare and just needed a few simple fittings. After checking that the FT-857, LDG Z11Pro11 Tuner and battery would fit inside, I cut the copper pipe and started to assemble.oliveve backpack Once the frame was dry assembled I tested the equipment for fit before soldering the frame together using a blow torch.targus backpack mumbai Soldering the frame was easy but I wish I had used the type of connectors that are not pre soldered. tulu backpackThe ones I used had a ring of solder inside the connector so I had to make sure each connector had the correct tube inserted before I applied heat.

A quick test fit in the pack to make sure it fitted. With the basic frame done, I cleaned it up and started to add the fittings. First, some aluminium strips to support the battery. I tried to solder the strips to the copper but it was very messy so I ended up using some small rivets instead. Next up was the strips and bracket to support the FT-857. Followed by the antenna connection brackets and ATU support. I cleaned the frame again and rubbed it down with wire wool before giving it a coat of paint. I used some “truck bed” paint from the local auto store which was billed as “hard wearing” and leaves a textured (think sandpaper!) finish. I wanted to soften the frame up a little and protect the paintwork on the base and handles so I found some DPM bandage (originally for my dogs injured leg) and used it to wrap parts of the frame. It’s a bit spongy and makes the handles a bit more comfortable. The LDG tuner was attached to the frame with some double sided foam tape.
