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, Jeff Anderson KD7PAW ----- Original Message ----- From: "Eric Ward" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Tuesday, June 22, 2004 7:32 AM Subject: [Elecraft] Dumb(?) dummy load question 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. _______________________________________________ Elecraft mailing list Post to: [email protected] http://mailman.qth.net/mailman/listinfo/elecraft You must subscribe to post.
