Have you done the IF OUT Gain Mod mentioned at the top of page 5 in the manual? http://www.elecraft.com/K3/mods/IF_Output_Buffer_Gain_Mod_Rev_A.pdf Earliest P3 firmware versions had a gain error of ~10 dB but the latest version (beta 00.30) is better. My P3 now reads -74 dBm for all combinations of PRE/ATT on and off (using the XG1's -73 dBm setting). Once Alan implements Amplitude Calibration we should be able to correct the remaining errors. 73, Bill -- View this message in context: http://elecraft.365791.n2.nabble.com/P3-Power-measurement-with-the-P3-tp5419099p5419585.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
