Portable HF station

This is a portable HF (High Frequency) HAM Radio station I built a couple of years ago.  This has been a great grab-n-go box and has served me well.  I update/re-configure the box from time to time according to my personal needs and preferences.

army_surplus_boxA few years ago, I was browsing through an Army Surplus store here in my home town, and came across an all aluminium case for a pair of night vision goggles.  Unfortunately the goggles weren’t included, however the case seemed promising.    Each half of the case is built from a single piece of aluminum with the handles and latches riveted in place.  On one side of the case, just below the carry handle is a pressure relief valve.   The case is approximately 13 3/4 ”  X 15″ X 11″ deep and is air/water tight.  This seemed like the perfect case for a portable radio project.

The radio I had planned for the case was an Icom IC-706MkIIg.   A great (though slightly outdated) all mode / all band radio.  I wish the CIV control was a bit better on this rig, but all together a great rig.  I wanted something that I could plug in and run with out having to connect a lot of wires and cables so it made sense to incorporate an auto tuner, and external signal meter into the box and I just happened to have both lying around.

Finally, the whole box can be packed / unpacked in under a minute.  With everything incorporated, the only connections are 12v in, HF / UHF-VHF antennas, and ground.
