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

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? 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
