Director, NW Division, Technical Resources It was one thing to have guessed it, another to have had that guess confirmed beyond possibility of refutation. Arthur C.

I am using it connected to three antennas and it will not tune the antenna in the #3 socket. During troubleshooting, I have hooked it to a dummy load, with new coax and it says high SWR. Tuning on the other antennas seems to be suboptimal. It has intermittant high SWR on the other antenna outputs but now #3 seems to always show high SWR. Has anyone seen this or has any ideas? I am running it with a KPA 500, but never over 250 watts. The antenna is a G5RV. The antenna matches OK using the internal FlexRadio 6400 tuner... > //dave > WB7ELY > ______________________________________________________________ > 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 > Message delivered to [email protected] ______________________________________________________________ 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 Message delivered to [email protected] ______________________________________________________________ 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 Message delivered to [email protected]
