How to build a QRP dummy load.
What do you need:
A box, in my case and aluminium box so it also the heatsink
a SO 239 Socket (or BNC / N Socket, just what you prefer)
A Non inductive resistor 50 Ohm, I used an MP930 50 Ohm 1%.
Small piece of coax
Some nuts and bolt

The MP930 resistor can handle more then 5 watts. 6 times as much, but then it will get realy hot. So Now I have a stable QRP dummy load.

So here is a quick foto how to on putting it together:

The parts

Make the hole for the socket and for het bolt that holds the resistor

Get the Resistor an socket in.

I did it like this

Mount the little piece of coax RG-58 will do fine as it’s QRP only

Test for faulty connections

And youre done. Mark it.
