Chuck- congrats on some very nice work! However, I'm having problems getting hf_explorer_4.py to recogonize my powermate. I get the error "Unable to find PowerMate or Contour Shuttle" even though I've got it on /dev/input/event5.
I verified that the powermate driver is running by using the "rotomatic" utility in the powermate-1.0 package to verify that the system was responding to powermate events. Any suggestions? thanks eric On Fri, 3 Jun 2005, cswiger wrote: > Gang - Just have to brag, I'm listening to a gnuradio live in > my apartment that rivals my TenTec RX320, and *much* more > flexible to boot ;) > > The project came together in the last few hours using > > 1) Antenna - a small swl magnetic loop.
