Gear: Yaesu FT-891, Windows 10, digirig-891. It appears that I have to manually change menu settings when bouncing between VarAC and Winlink. Can VarAC save current transceiver menu parameter values when it starts, make changes to menu parameters necessary for it to run, then change them back when exiting? I use Vara (licensed) with Winlink. The Vara waterfall and the red bandwidth lines look like they do in the manual - the red lines are far apart, just inside each edge of the waterfall. This morning I installed and ran VarAC. One obvious difference in the waterfall was it was perhaps 1/6th the width of the waterfall when running Winlink and it wasn't centered but off to the right. However, what was concerning was that the two red lines that indicate the bandwidth were much closer together (about 1/6th the width as in Winlink) but more concerning was that the red lines were centered on the Vara window, which meant that none of the VarAC waterfall was within the red lines. A bit of research on this forum suggested that I should change Menu 08-03 (OTHER DISP) to 1500 Hz and also change 08-04 (OTHER SHIFT) to 1500 Hz. After doing that, the waterfall was centered between the two red bandwidth lines. So far so good. But when I exit VarAC and run Winlink, the 1500 Hz values make the red bandwidth lines narrower than what is recommended for Vara. Best, Jim / K8DDV
