GTK+ GUI running on Mac

I finally managed to get ghpsdr compiled and running on the Mac. There are some USB performance problems that need to be resolved, but it is running. Required changes to the semaphores (I had forgotten that the mac did not like unnamed semaphores) and the libusb_open_vid_pid does not claim the interface as it does on the Linux version.

I will try to update the repository in the next couple of days.

192K and display updates 30 times per second

I tried running at 192K with the display rate for the Panadapter/Waterfall running at 30 updates per second. Uses about 60% of the cpu (3.4GHz Intel dual core), but still no pops on the audio using the pre-2.7 Mercury/Ozy code that Phil will release when they have resolved a couple of problems. Now I can read the CW ;-)

VLF Radio Time Signals

I was looking at me radio controlled clock and wondered what the signals looked like that they use. First time I have tried Mercury on VLF frequencies.

You can see the 3 time signal stations MSF on 60kHz in Rugby, England, HBG on 75 kHz in Prangins, Switzerland and DCF77 on 77.5KHz in Mainflingen, Germany.
