The next Logger32 update will include support for the Griffin PowerMate USB knob. I you have a Griffin (or maybe a pryde of Griffins :) set them up as follows:
To control the primary radio, program your Griffin: CTL+> for up xHz, CTL+< for down xHx, ALT+CTL+> for up 1000Hz and ALT+CRL+< for down 1000Hz.
To control the SO2R or SO2V, program your Griffin: CTL+upArrow for up xHz, CTL+dnArrow for down xHz, ALT+CTL+upArrow for up 1000Hz and ALT+CRL+dnArrow for down 1000Hz.
To enable the global hotkeys for the Griffins, click SETUP | HOTKEYS | POWERMATE GRIFFIN USB VFO KNOB.
The above description of Griffin programming refers to xHz. xHz is a small frequency increment.
Logger32 has a feature that allows the user to roll their mousewheel over the frequency display on the Logbook Entry Window. This moves your VFO up/down by small increments. Right click on the frequency on the Logbook Entry Window to show a menu of frequency increment options. Set this to suit your operating style. If you are familiar with rolling the mousewheel over the frequency display to move the VFO up/down, then you know that holding down the SHIFT key while doing this multiplies the increment by a factor of 10. The same applies to spinning the Griffin wheel.
For the more creative user, you could of course program a single Griffin to control both radios: CTL+> for primary radio up xHz, CTL+< for primary radio down xHz, CTL+upArrow for SO2R/SO2V up xHz, CTL+dnArrow for SO2R/SO2V down xHz,
