Barry, Sorry but what do you mean by 'high isolation headphones'. Would the Heil Pro-Set Plus do? 73 Doug EI2CN

High isolation headphones are critical because you want to set gain such that weak signals are lightly heard but clearly copiable. You're maximizing the receive dynamic range delivered to your ears and the high isolation means you can clearly hear fainter signals without turning up the gain and squashing the dynamic range (and too frequently engaging AF Limiter with AGC Off). 73, Barry N1EU -- View this message in context: http://n2.nabble.com/K3-in-a-cw-pileup-needs-work-tp4523884p4527626.html Sent from the Elecraft 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:Elecraft@mailman.qth.net 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:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
