Brett, I'm using the Aux RF inputn but in looking at the block diagrams it looks like all of the Ant inputs are COR protected.
I didn't notice any problems activating the COR, but I'm not near anyone else and I was running QRP as well. My doublet runs N & S about 15' to the right of my operating position (up 35'). I then have the short beverage running E & W starting at my operating position going away from the doublet. Not sure if this helps you or not... 73, Dave W8FGU -----Original Message----- From: "Brett Howard" <[email protected]> Date: Tue, 14 Jul 2009 09:26:03 To: <[email protected]>; 'Vic K2VCO'<[email protected]> Cc: 'Elecraft Reflector'<[email protected]>; 'Bill Tippett'<[email protected]> Subject: RE: [Elecraft] K3 Diversity Rocks! Are you gentlemen using the second KAT3 port or are you using the AUX RF path? I tried using the KAT3 port and found that with other stations around my COR's were switching on me when the other station got into us a little bit. Their antenna was as loosely coupled to ours as I could have gotten it in the space we had. There were two windoms both on the same string between trees so they were end to end of one another tip to tip. Then our other antenna was 90 degrees off and when we TXed I found that it would get into the other port and operate the CORs that way as well. Does this possibility go away when you come in through Aux RF? ~Brett -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Dave Van Wallaghen Sent: Tuesday, July 14, 2009 6:39 AM To: Vic K2VCO Cc: Elecraft Reflector; Bill Tippett Subject: Re: [Elecraft] K3 Diversity Rocks!

One problem I have copying weak CW signals is that sometimes a bit of noise comes along and causes me to miss a letter in a call, for example, and I have to wait for the guy to send it again. During a QSO it's less of a problem because the brain fills in letters and words from the context, but sometimes I am missing almost every other letter and this mechanism breaks down. Possibly the noise is picked up differently by the antennas...I'm not sure, but when diversity is on, the signal seems to stand out, less damaged by the noise. Far fewer letters get crunched -- it makes it much easier to copy. ----------------------- Yes, that is exactly what I heard as well. The sound was much richer and full and the sigs just seemed to pop up out of the noise better. Doing A/B comparisons between diversity and single receive I heard much more ringing in narrow DSP filtering on single receive that combined with the noise would tend to bury some signals. But with diversity reception, the signal would seem to pop out more and sound better with much less ringing or harshness. 73, Dave W8FGU ______________________________________________________________ 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 ______________________________________________________________ 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
