Mike: Thank you for settings cross-check (current settings): Others have proposed reducing RF level (need to adjust AF level to preserve EME system noise figure)
K3S entryValuecomments AF GAINLOreduces output level by about 10dB vs. HI setting AF LIMNOR 030don’t want AGC limiting levels for optimal EME decoding LIN OUT=PHONESNOR 000 gives 0dB while NOR 001 saturates WSJT-X at +78dB With LIN OUT set to =PHONES, I can use the radio K3S AF control to somewhat control the audio out level via the USB port, but it’s super sensitive. A 10-Turn trimmer AF control would be required to set it properly. The audio output abruptly jumps from zero to too hot when using the radio’s AF (volume) control. Also I’ve checked the computer MIDI settings (already at minimum). I have searched for WSJT-X audio settings and K3S on internet (N5XLHamRadio.blogspot.com has one good post but it must have referenced an older WSJT-X version that had Rx input slider). I’ll keep researching settings and welcome an email off-list from anyone who finds alternate solution on this to kj9idave (at) charter ( d ot) net Absent an Rx input level slider-control, I believe I just need to live with/accept the the 57dB level currently showing (no signals) on WSJT-X with Ref Spectrum measured viewing Cold Sky North. thank you Very 73, Dave KJ9I From: Black Michael via wsjt-devel <wsjt-devel@lists.sourceforge.net> Reply-To: Black Michael <mdblac...@yahoo.com>, WSJT software development <wsjt-devel@lists.sourceforge.net> Date: Monday, March 15, 2021 at 12:01 AM To: WSJT software development <wsjt-devel@lists.sourceforge.net> Cc: Black Michael <mdblac...@yahoo.com> Subject: Re: [wsjt-devel] Feature request: Rx level input slider Have you tried this setting? Seesms reducing this should work. LIN OUT NOR 010 Sets the LINE OUT level. LINE OUT connections go to PC soundcard inputs. Settings above 10 may result in overdrive of the soundcard or saturation of the KIO3’s isolation transformers; monitor signals using the PC to avoid this. Note: Normally, LIN OUT sets a fixed-level receive-only output for main/sub (L/R), compatible with digitalmodes. Tapping 1 switches LINOUT to =PHONES, where the line outputs match headphone audio, audio level is controlled by AF/SUB gain controls, and both RX andTX audio are available.

More detail/context: Elecraft K3S radio with WSJT-X users who use the USB-to-K3S radio interface can only reduce the input volume so far (typically maintains 60dB WSJT-X level on the Rx dB level indicator). Further reducing the audio output of the K3S drops the Signal to the point we see ‘jail bars’ (internal noise). To enable setting K3S output to WSJT-X recommended 30dB, the above Rx level slider would help. Tx slider seems unnecessary because every radio (correct me if wrong) allows a Tx or drive level reduction on the radio itself).
