Elecracft K1 Xcvr in blue bag
Blue bag by JeanneE, KA1PMS
33ft radiating element - black reel
Four 36-ft radials - 2 spools & 2 PVC
WB2MIC homebrew junction box
Homebrew Hoze Key (paddle)
7AH AGM sealed battery
5 Female black banana jacks
1 Female red banana jack
1 female BNC connector
Female BNC = rig coax
Red female banana = radiator
Black female banana top = ground
Black female banana sides = radials
BNC center female is connected to the center of the red female banana jacks and isolated from ground.
5 black female banana jacks grounded through their lugs to the truffles tin
There are two copper braids connecting the top lid to the bottom of the truffles tin to insure both are at common ground.
The basic schematic (unlabeled) is on the left. For larger printable schemtics with text labeling click below.

Antenna
Hardware From left to right: 30-in. copper ground rod 36-in. metal fence stake 33-in/ 1-1/4in PVC pipe 4-ft collapsed Jackite fiber- glass 31-ft telescoping mast

The metal fence stake goes in the ground first.
The PVC pipe goes over the fence stake to protect the Jackite mast.
The Jackite pole slips over PVC pipe.
The 33ft radiating wire (red banana plug) wire is then wound around the mast and hoisted up.
Fours radials are plugged in along with the ground rod (black banana plugs).
The coax is hooked up to BNC.
Everything fits in this convenient carry bag except the brief case solar panels, jackite mast, PVC protective tubing, and ground rod.
Topray Solar 12 watt panels. Open voltage measured while running in living room is 21 volts. I use this with a charge controller to safely maintain a 7AH AGM battery. It weighs about 2-3 pounds.
Inside pix of the opened solar panels. Everything DC in the QRP station & the home QTH is Power Pole compatible. And yes, that is my reflection in the solar panel glass. And indeed, that is a kyak up on the rafters. One of two.
Pics of station in operation below
I take the QRP station into the field and often set up on the tailgate of the pickup truck. This operation and the pix below are operating from the Lake Saint Catherine State Park Marina in my home town of Wells VT.

I learned my lesson the hard way.
On this field operation I remembered a chair.
This is the voltage across the 7 AH AGM battery during operation.
Max volts (RX) = 14.9 VDC
Min volts (TX) = 14.8 VDC
TX power output = 5.2 Watts
SWR = 1.1 to 1.0 on 40, 30, 20 and 15 meters using the K1 internal tuner and the 33ft vertical with four 36-ft radials
This is a bit hard to see in the very small image at left so click on large and very large below.
Copper pipe = 3ft ground rod
Black pipe = 31 ft Jackite mast
Box in middle = junction (see above)
Coax choke balun
6 White wires: ground, radiator and 4 radials.
