[Flexradio] CPU performance spike

I'm using a 1500, 2.0.19 and a Sony Vaio laptop. As I monitor the CPU usage in both the software and in the Task Manager...I notice a spike every 15 seconds. Typically 5-10% then spiking to 60-70%...every 15 seconds. Both transmit and receive are effected by this. When I shut down the software, th

Re: [Flexradio] Values

You don't need to use demo mode to play back an IQ recording. Matter of fact it is better to use the DACs in the radio than the ones in your PC sound card. Can I rinse my shoes off with the garden hose and be done with it? :-) CW is a bit trickier because it is MUCH more PC dependent that Phone

[Flexradio] Values

Tim, Now you have stepped in it. I realize that the setup values you mentioned are very dependent on the "other two-thirds of the radio", these are good starting places for new guys (especially w/o the wicki). How about a rough set of numbers for SSB and CW to use with this set for Digital.
