Dick, My 1000' beverages are WAY too close to my 160 phased vertical array (about 100' max at the closest point) running the legal limit power but I have zero RF getting back into the K3 when transmitting and I use NO external relays to protect the K3. I have K3 S/N 234 and 752 and I believe I remember adding the strong signal overload mod since these are older models, but I've only seen that COR activated one time when I was playing around on the workbench. I've never seen it kick in during normal operation. Something has to be abnormal with your installation or the rig itself. Like Wayne says, [email protected] can help you figure it out.
I hope to see you this weekend in the CQWW 160 contest because I'll be plowing away to the best of my staying awake powers. ;-) GL, Bob K5WA >>>>>>>>>>>>>>>>>>>>>>>>>>>>> Message: 26 Date: Tue, 25 Jan 2011 01:18:25 EST From: [email protected] Subject: [Elecraft] K-3: Unswitched Rx Ant To: [email protected] Message-ID: <[email protected]> Content-Type: text/plain; charset="US-ASCII" Hi Guys, Please correct me if I'm wrong, but I believe the K-3 Receive Antenna is unswitched during tranmit... which allows high RF to get back into the receiver. That's sure the case when using my beverage for receive and transmitting on 160-meters. (sounds like my K-3 is going to blow up) I'm wondering why this is the case. Couldn't an inexpensive relay be added to the KXV3 to prevent his problem? I'd appreciate knowing what others are doing to prevent your K-3's from blowing up while using beverages on 160-meters! Is everyone building an external relay box just to switch the beverage off during transmit? Thanks & 73, Dick- K9OM ______________________________________________________________ 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
