I think you will be impressed with the diversity performance of the K3, to me it was well worth the investment. Just using my available antennas being very close to each other I have noticed a big different receiving DX signals with QSB on 160 meter. Here is a recording of 4X4DK calling using diversity. Every time the signals tilts over to one side, the signal has dropped out of the other which proves that two antennas are better than one. Another thing worth notning is that the static discharges you hear in the beginning of the call is stronger in antenna than the other, so not only wanted signals are improved but diversity can also help fighting QRN depending on its nature. Recording: http://sm0mdg.com/audio/4X4DK-div.mp3 If I remember correct, the left channel is an East pointing pennant and the right channel is a 20 ft coax loop. I wish I hade more recordings at hand, but I am sure others have and can chime in. 73 de Björn, SM0MDG SE0X ______________________________________________________________ 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
