Re: [Elecraft] K3 S-meter reading and coax input or antenna voltage ?
At the antenna spigot.

A table I found on the Internet for singals below 30 MHz says that an S-9 meter reading is a signal of 50-microvolts but where in the system is that registering 50 microvolts. At the input the K3 or some other circuit within the K3? Thanks -- just mostly curious about this and the connection between S-meter reading and actual signals input to the receiver. 73, phil, K7PEH __ 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 Message delivered to wes_n...@triconet.org __ 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 Message delivered to arch...@mail-archive.com

Phil, With the original K3, S Meter "ABS" mode the S meter is referenced to the signal level at the antenna jack. S9 = -73 dBm = 50 uV into 50 ohms. In the other S Meter mode, the reading varies with ATT and PRE settings, as well as signal level. 73, Lyle KK7P On 1/23/19 10:00 AM, Phil Hystad via Elecraft wrote: If I had an S-meter reading, S9 for example, on my K3, what could I infer about the voltage level of that signal at the Coax input to my K3? __ 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 Message delivered to arch...@mail-archive.com
