Griffin PowerMate USB Knob as SDR VFO
« on: September 13, 2014, 1321 UTC »
I just want to mention to those who desire a VFO knob for their SDR, I have successfully been using a Griffin PowerMate USB Knob as a generic VFO & Master Mute button for a while now...

At under $40, it is easy to program for things your mouse won't do easily & gives you back the "feel" of the Big Knob, missing from our beloved black boxes...

I simply programmed:
Spin Right = UP
Spin Left = DOWN
Click = MUTE

with 2 spare functions TBD

Take a stroll up/down the band with a VFO feel  ;D

I used one for a while with SpectraVue and an SDR-14 or SDR-I/Q.  I had it set up so Left / Right were tune up and down, Press and Turn moved the digits position.  This allowed me to use the knob to tune in whatever steps I wanted, but I never really liked it, possibly because even using this there was still a lot of keyboard / mouse action going on.  I never really got to like it, but it did work well, if I had given it more of a chance it probably would have grown on me more.

For my G31DDC and G33DDC I use the XKeys Jog Shuttle Pro.  This allows for almost every function to be done without ever touching the keyboard or mouse.

SdrDx lets you use MIDI devices. So a MIDI controller with lots of sliders, knobs, and buttons gives you quite a few control possibilities, and they can be picked up on Amazon fairly inexpensively. Not sure if other SDR apps support MIDI or not.

Of course, this may set back the whale oil as a renewable energy project for awhile.
