Michael, One issue I found, was that even though I followed your instructions, I had my Win10 set to 2 channel 48Khz for recording. Audio cleaned up very well once I set it to 1 channel 48Khz

If you are unable to get at least 90W with no ALC then something in your audio path is incorrect. I'd like to work with you and ensure that either my directions need updating or your settings need updating. Did you follow the procedure in the document I sent? That has worked on every rig/audio combo I've tested which is over 300 operators now. Can you call me an we can hook up and figure this out? Gotta' make sure the info I'm putting out is as inclusive as possible. 321-690-2551 Mike W9MDB On Thursday, June 6, 2019, 1:24:58 AM CDT, Gary - K7EK via wsjt-devel <wsjt-devel@lists.sourceforge.net<mailto:wsjt-devel@lists.sourceforge.net>> wrote: Absolutely. I own six different Icom HF rigs. All of them put out minuscule power unless there is a significant deflection on the ALC meter. The no ALC warning does NOT apply to all rigs. I agree with RTFM. You cannot go wrong.

You better feed that 7300 some ALC if you want it to perform. All radios are NOT the same and some need ALC.

For one thing (operator error, no doubt), I've never checked that the sound card sample rate was 48kHz 16-bit before, and of course it was not. Thanks a lot! 73 de Tom OH6VDA Sendt fra min iPad Air 2 5. jun. 2019 kl. 15:01 skrev Black Michael via wsjt-devel < wsjt-devel@lists.sourceforge.net<mailto:wsjt-devel@lists.sourceforge.net>>: For the IC-7300 you want the ALC meter to show no action at all. So if it ever bumps up at all you've got too much audio going into the rig and need to back off the USB Mod Level. You should be able to transmit 100W with no ALC (or very close to 100W). That is the goal of all rigs....some of the newer rigs will show < 0dB ALC (e.g. K3) though so it pays to learn what your ALC meter is really telling you. The way you do that is set your rig for 100W, WSJT-X power slider at -3dB, computer audio out at 0dB, then adjust rig/external sound to show 50W tranmit power going out. That should be 0dB ALC and shows you what to expect when transmitting close to the 100W. Many rigs cannot do 100W with no ALC so have to back off to 95W maximum or such. So as you gradually increase the power slider in WSJT-X (use the up cursor key) watch your ALC as you approach 100W. If you start seeing ALC you have to back off the audio level at the rig or external sound card so the WSJT-X slider can be at 0dB and no ALC showing. de Mike W9MDB On Tuesday, June 4, 2019, 12:06:34 PM CDT, Black Michael via wsjt-devel < wsjt-devel@lists.sourceforge.net<mailto:wsjt-devel@lists.sourceforge.net>> wrote: If you reduce power from WSJT-X (not from the rig) does your ALC drop?
