Simple, accurate (1%) and inexpensive dummy loads you can homebrew is here:
http://www.n0ss.net/dl_30w_hf-uhf.pdf They are based on the Caddock resistors Don mentioned; either 30 or 100 watts. The resistors are available for a few dollars. All that's needed with the resistor is a suitable heat sink and connector. Ron AC7AC -----Original Message----- Tom, I agree. Actually, right now I do not trust my dummy load for being close to pure resistive 50 ohms. Indeed, I did not test it at the beginning and this is what motivated me to post the question. I think I have enough to test the DL but won't have time to do it for a week or so. peh On Dec 22, 2011, at 12:59 PM, Tommy Alderman wrote: > BUT just because you bought it direct from Palstar does not mean it is a > good dummy load!
