Dear Bill, Thanks a lot for the clear explanation and fully right to follow the manufacturers direction but I was ? about it considering my "jurassic" habits. I will use the indicated config as you mentioned as I'm still in the K3 pre-school ! New rigs, new technologies....Ham radio is great to stay younger ! Thanks to Elecraft ! Bst 73's Philippe A65BI / F5LTB (and ex 9Q1TB & many others...)

A more complex one is that the K3, being a DSP rig, compensates internally in firmware for the fact that PREamp is ON during the calibration procedure. I also recommend using CONFIG: SMTR MD - ABS. This will place the K3's S-meter in ABSolute mode, so that the S-meter always reads the signal being applied to the input terminals correctly, independently of whether PRE or ATT are selected internally. This is also different than most rigs but, if you think about it, it is better since the S-meter always read the true signal level at the input terminal, before any gain or attenuation is applied inside. 73, Bill W4ZV -- View this message in context: http://n2.nabble.com/Re-K3-S-Meter-tp4019422p4024549.html Sent from the [K3] 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 ______________________________________________________________ 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
