As Tim will tell you; Being able to operate a Flex on a laptop (or any computer) has about ZERO to do with the processor speed of any processor they have made in the last 10 years or so. I used to run my flex on a Pentium 4 with 1 Gb of RAM with no problems.
I've tried about 8 different laptops on a Flex. I've had ones with more processor power work poorly while older ones worked well. There is no predicting as to which one will work well. It comes down to the solidness of the bus and the components, not the processor. With the shrinking of components for a laptop, comes trade-offs in the hardware. And in the production of laptops, it often comes down to low bid from their suppliers, unfortunately. This is where the DPC latency comes in. So don't think that a laptop won't handle CW, it just takes a good laptop. For what it is worth, I've noted that T series Lenovo's I've tried worked pretty well. The Dells and HP's I've tried seemed to have poor DSP numbers, but perhaps that was just the luck of the draw on the models I checked. But laptops all seem to suffer if the built-in wireless network adapter is left running. I wonder of using a USB dongle wifi adapter would make a difference? 73, Scott AC8DE -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of George Allen Sent: Sunday, July 01, 2012 3:31 PM To: Ted Leonard; [email protected] Subject: Re: [FlexEdge] older slower laptop I have a Dell Laptop that I used with my F3K. Worked well with the F3K; but, does not work well with the F1.5K. Too much latency for CW. Was going to take the laptop and F1.5K with me on field day; but, latency was really bad. The Laptop is a dual core Dell (not sure of the speed). The F1.5K works well with the W7 multicore desk system, so took the big computer and F1.5K on field day.

While I realize a 1.6 gHz laptop in XP is pretty minimal for my Flex I would like to try it on a quick portable op as the laptop runs happily on 12VDC thus eliminating the need for an inverter. It has a firewire port (unknown chipset) but has the small rectangular connector on the computer for the firewire cable, I am guessing there is a standard cable on one end that would go to the Flex and the small rectangular connector on the other end that would go to the laptop or it it just a little adapter I would need. (any part reference would be helpful) Other option would be I think to use a proper Firewire card in the card slot it has it will take up to two type l or ll cards or one type lll card what would be the proper Firewire card to get for this? Then I could use the Firewire cable I already have. Or am I way off base---I do realize it would be a minimal setup. It is a Panasonic CF51 Toughbook.
