Since 300 Hz is as low as the K3 PITCH goes, don't you also have a 250 Hz offset when listening at 50 Hz? Wow...I thought I liked a low PITCH but this is the first I've heard of anyone using 50 Hz! 240 Hz is as low as I ever used with my old TS-930S for weak signals...coincidentally when working 4S7 via long path on 160m from Colorado (truly a weak signal). I have a recording of that on cassette tape and later verified the PITCH setting was ~240 Hz: http://users.vnet.net/btippett/jj1vkl_4s7.htm More recently I used a 270 Hz PITCH to win N2XE's 80m beacon reception test at 27 uW output: http://www.n2xe.com/Beacon.html (270 Hz PITCH mentioned near bottom of page) 73, Bill -- View this message in context: http://n2.nabble.com/K3-NR-tp3515712p3518890.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:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
