There is an error in the time base calibration. I set the radio to
receive a signal generator with a 1kHz AM. Setting the Time (us) to 10
it shows almost 7 full cycles in the scope, so it is closer to ms that
us. I had to stop the radio to steady and count it, since I already
noted there are not trigger facilities. I think it doesn't worth to
report this calibration issue to the bug tracker since it is not needed
until more elaborate scope controls are available.

Bill,
Here it works more or less as it should. The speed function surely
works, but I didn't checked if is really calibrated and I see some
discontinuities, for example when looking a sine wave. It lacks
trigger functions and a pop-up control panel (maybe in a future
version), but I found it quite useful.

adjusted the Speed parameter and note little change. The sweep

if I
got a better video card? Right now, I am using the integrated Intel

chipset that came with my Dell Inspiron 530 (dual core, 2.2 GHz, 2MB
cache
on each core) with 2 GB 667 MHz DDR Memory. I do have a vacant
PCI-Express
slot where I could install a dedicated video subsystem.
Any thoughts? Thank you
