Hi, I gave a test to my PSK31 setup today - barefoot K2 #5932 with M-Audio sound card in my desktop pc. My laptop pc was connected to a FT-840 and listening. Both used old good DigiPan.
I let my laptop measure IMD and also asked for this value during QSOs. In all cases it's about -16dB which is very poor I beleive. The power level is set to 5W. PC sound output level was decreased so that only the first ALC bar blinks. I also tried power levels setpoint from 0.1W to 15W. IMD value changed continuosly from -19dB to -12dB. Anything I could try/check to figure out the reason of destortion? vy 73 de DL2IPU Oleg -- View this message in context: http://n2.nabble.com/poor-IMD-on-barefoot-K2-even-at-low-power-tp3598729p3598729.html Sent from the [K2] 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
