Battery Box in Vehicle:

This battery box with deep cycle battery is behind the driver's seat. It can also be moved to a park bench if need be.

The black and red wire comes from a socket in the back which supplies power to charge the battery while the engine runs.
This battery allows the IC-7000 (installed vehicle radio) to work off of clean DC power while the engine is running. I no longer hear the alternator whine.
Installed are Power Pole connectors with cigarette lighter socket. This battery box is currently in the travel trailer. Rig is plugged into DC power socket.



40 Watt Dummy Load:

I needed a QRP - 50 Ohm 40 Watt dummy load.
I found this article from CQ February 2003 "A Dummy Load for Just Pennies" by Irwin Math *WA2NDM.
I actually had from my junk box 20 - 1K Ohm resistors, some perf board and a coax connector with a bit of coax in it!
I covered it with heat shrink. Works just fine.

Microwave Cart Station Console






Travel trailer Station Console: K3, KPA500 amp. and KAT-500 tuner. Icom-V8000 2M

I made these bookends with the help of John KI4UIP's shop and expertise.
They are made with a pair of 829B double tetrode twin beam power tubes with sockets.
These tubes are normally used as push-pull RF amplifier and oscillator class C telephony
and/or push-pull RF power amplifier class C FM telephony in ham radio.

9:1 UNUN QRP - 50 watts Maybe. It is used with 33 feet or so lenght of wire.

The 9:1 is used with any wire length from 23 feet to 60 feet. The 4:1 Balun is for 200 or 450 Ohm feed line.
