[Elecraft] Dumb(?) dummy load question

[Jeff Anderson]

Hi Eric,

I tried this once.  The 10W 50 ohm resistors that I purchased at RS are
wirewound, and make a terrible load at RF frequencies.  The higher the freq,
the worse they get.

For reference, I just grabbed one of my resistors, and made a few
measurements with the MFJ antenna analyzer:
3.75 MHz measures as 1.9 SWR
7.12 MHz measures as 3.2 SWR
14.1 MHz measures as 7.6 SWR

Your G5RV through a tuner probably IS closer to 50 ohms, but some
combination of carbon resistors (for a total of 50 ohms) would probably be
even better.

73,

In an attempt to save pennies, I got a 10W 50 ohm resistor ($1.79 for two)
at the Shack and soldered it to a male BNC--I figured this would make a
serviceable QRP dummy load.  The resistor checked out at 50.0 ohm on my DMM.
