Does anyone know of available software that will do this? I'd love to be able to forget setting the grid in WSJT-X when roving in VHF contests. 73, Steve VE3SMA

Hi Michael: The bad setting is that the value of RPORT GAIN (effectively the transmit audio gain for the rear and USB ports) is set by PRESET to a default value of 10. This provides insufficient gain

Hi Alan The ALC meter is active, and the power output is as set on the rig (for any setting between 5 and 100 W) and does not vary with small changes at the WSJT-X Pwr slider, so yes, I believe the AL

To answer Eric (KK4KYE), my new Yaesu is an FTDX10. It is really, really easy to overload the transmit audio if the input is through the USB route - several owners have complained about audio harmonic

There seems to be "received wisdom" that for non-Elecraft radios one must operate WSJT-X modes with no ALC action. Having recently acquired a new Yaesu radio, I found a variety of videos and reflector

Thanks for the clarification, Bill and Reino. Is the Q65 ramp amplitude shape and timing documented somewhere? I couldn't find it in the User Guide or the Quick Start Guide. Does it vary with sub-mode

WSJT Sensitivity V MSHV #why ?
It's interesting to note that, in the example in #25583, the messages decoded in both programs show a much better SNR in MSHV than in WSJT-X. 73, Steve VE3SMA
