To the right is my QRP "Station in a Box", that I keep in the car for portable QRP ops.
The case is an aluminum one that I got from Harbor Freight. It is 12" X 16" X 5". I don't remember what I paid for it; but I got it on special when it was dirt cheap.
It's a lot fuller than it used to be (as in the picture). It is currently populated by the following:
K1 with autotuner
12V 5Ah sealed lead acid battery
Emtech ZM2 tuner as a backup
Autek RF-1 antenna analyzer
LDG 4:1 balun
NorCal Doublet which I keep wound up on an empty monofilament fishing line spool
A Glad storage container with a Bulldog paddle, Morse Express Christmas straight key, cable for the battery to rig, an extra small jumper coax (about 12" long), allen keys for the Hamsticks.
Cheap-o set of Walkman type headphones. I also keep a roll of twine in there for doublet support ropes, a Swiss army knife, and a pad and pencils for taking notes during QSOs.
Also in the back of the car is the Black Widow crappie pole with homebrewed support mechanism, the PAC-12 and Hamsticks; as well as a canvas folding chair and a canvas collapsible camping table.
The only thing that I need to remember to bring along from time to time is my solar battery charger, which I keep in a safe place at home so it doesn't get damaged.
It pretty much has everything I need to set up a temporary QRP station in the great outdoors. If need be, I can transfer everything to a backpack if hiking becomes necessary. This is more in the line for setting up in a park or a picnic grounds.
