Re: [Elecraft] KX3 Question on S-Meter Calibration
I thought I understood this but appears that I had it wrong. According to the SMTR calibration procedure, it is set with the PRE on and ATTN off. Calibration sets a 50uV signal to S9 and a 1uV to S2-S3. See this in the Calibration Procedures section of the manual (p51 in my 2009 version). I’ve been using the SMTR ABS mode ever since I discovered it.

Re: [Elecraft] KX3 Question on S-Meter Calibration
I’m pretty sure the K3 has an S-meter absolute mode that adjusts the S-meter reading when preamps and/or attenuators are turned on. The KX3 is supposed to have that mode, but it is not implemented. From the manual errata: "Not implemented: S-meter absolute mode (MENU:SMTR MD); addressing of multiple transverters (XVn ADR)." https://ftp.elecraft.com/KX3/Manuals%20Downloads/E740163E%20KX3%20Owner%27s%20Manual%20Errata%20C5-3.pdf wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Oct 10, 2022, at 2:04 PM, D Remy wrote: > > Does that also apply to the K3? > > David R Hourdequin, PE > 828-421-6216 > >> On Oct 10, 2022, at 14:20, Don Wilhelm wrote: >> >> Greg, >> >> The KX3 is designed around having the preamp on most of the time. >> >> 73, >> Don W3FPR >> >>> On 10/10/2022 1:58 PM, WA1JXR ALGIERI wrote: >>> I have noticed with my KX3 that the S-Meter is not calibrated that is 50 >>> microvolts (-73 dBm) at the antenna connector equals a S9 signal only when >>> the preamp is turned on.

Does that also apply to the K3?

Greg, The KX3 is designed around having the preamp on most of the time. 73, Don W3FPR On 10/10/2022 1:58 PM, WA1JXR ALGIERI wrote: I have noticed with my KX3 that the S-Meter is not calibrated that is 50 microvolts (-73 dBm) at the antenna connector equals a S9 signal only when the preamp is turned on.

[Elecraft] KX3 Question on S-Meter Calibration
I have noticed with my KX3 that the S-Meter is not calibrated that is 50 microvolts (-73 dBm) at the antenna connector equals a S9 signal only when the preamp is turned on. Is this normal and the way the KX3 is designed? I thought it might be with the preamp off.
