Quick Homebrewing of a QRP Dummy Load for Testing N5ESE RF Probe

Quickly homebrewed a 5W fifty ohm dummy load using twenty 1K resistors, each of 0.25W, in parallel. The combination was soldered on to a PL259 connector attached to a small piece of 50 ohms coax. This was used to test the voltage generated by my FT-710 radio set to 5W output, using my homebrew N5ESE RF probe.
