I don't know what a MacAir is, I've pretty much managed to avoid the iWorld. I can tell you about the Raspberry Pi [and others] however. Raspberry Pi [and Beagle Bone, and several others] are tiny little processor boards with weird names that run some flavor of LINUX, and thus will run LINUX-based applications, a great number of which speak Internet/Web. You can do a great deal with them because of that. I built a 40-station irrigation controller for my wife using the Hamstack components [hamstack.com] based on a Microchip PIC. Aside from using their and Microchip C libraries, I had to write all the functional code in the PIC myself. The Hamstack guys [who I know quite well] have now added Beagle Bone and maybe Raspberry Pi to their line, which allows you to capitalize on already created applications and modules. Hope this helps.

Re: [Elecraft] Update on a Question About the P3 SVGA and Mac Computers
The Mac Air is a laptop. properly known as a MacBook Air. It's the 'netbook' variant of the laptops. As Far as I know, there is no way to use the internal display of a MacBook to display anything other than the OS or an application. That applies to anything with a display in it that Apple makes. 73, Joshua Gould K8WXA EM89pn On Thu, Jul 10, 2014 at 6:27 PM, Fred Jensen k6...@foothill.net wrote: I don't know what a MacAir is, I've pretty much managed to avoid the iWorld.

Re: [Elecraft] Update on a Question About the P3 SVGA and Mac Computers
I thought about this problem for a few minutes a few months ago. Decided it was not worth the hassle. Therefore, if I want a larger screen for the P3 then I would use an SVGA monitor that could be bought for $50 to $150 depending on lots of variables. But, if you want full rig control (logging at least) on a Mac then the there are a handful of products that do that but they do not include panadapter features (as far as I know). As someone has suggested, you could possible use a frame grabber which would take the SVGA output of the P3/SVGA and then display the results with a suitable app on your mac but that seems to be going way overboard and I am betting with less than excellent results. Fast real-time response on the P3 screen may be difficult with a frame grabber approach. I think there could be a great market (although likely free software) for a good Mac interface to a K3 or KX3 that is akin to something like the Flex Radio PC software. This would require something different then a P3, the LP-Pan type solution instead of a P3, but the KX3 could interface directly with its I/Q output. 73, phil, K7PEH On Jul 10, 2014, at 4:14 PM, tom armour wa...@hotmail.com wrote: Why not just look at the P3 display?

Re: [Elecraft] Update on a Question About the P3 SVGA and Mac Computers
Although Raspberry Pi is indeed a Linux system, the cpu is not Intel so any of the software that is available for Linux must be built from sources on the Raspberry Pi system (unless it is provided by rPI's distro). Not every ham radio operator is equipped to build large complicated applications from sources. Even though various Linux distros make this easy, it does not mean that everything is easy. So, to get a package buildable on Raspberry Pi Linux may require a bit more programming and Linux/Unix/GNU knowledge than typically held by the everyday ham. This includes fooling around with the configure script or at worse making source changes to the software. Plus, there are some available Linux packages that may require language compilers that are not available on the Raspberry Pi distro. 73, phil, K7PEH - 15 years of Linux development experience - 30 years of Unix development experience - 45 years as a professional programmer - But, I admit to less than 1 year of rpi development experience On Jul 10, 2014, at 3:27 PM, Fred Jensen k6...@foothill.net wrote: I don't know what a MacAir is, I've pretty much managed to avoid the iWorld.

Re: [Elecraft] Update on a Question About the P3 SVGA and Mac Computers
sigh This is not a difficult problem to solve. First off, the MacBook Air is _not_ a netbook. Netbooks are defined by their low-power processors (typically Intel Atoms). The MacBook Air has a full multi-core Intel I5 processor, which means it can do real work. The best way to approach this is to look for a USB video input device, such as those from El Gato, which can input video to the Mac. From there, just use the El Gato application to display the video, or save it to disk. I don’t know if El Gato has a VGA-capable converter, but I do know they have devices that can input other video formats such as those common to current TVs and DVRs. I believe their URL is www.elgato.com or something similar. You may have to search for a suitable device that does VGA, and I suspect it won’t be inexpensive. Still, worth the effort. I would expect the conversion task to take a notable amount of processor horsepower since much of the conversion occurs inside the Mac. This means that that extra horsepower you get because the MacBook Air is _not_ a netbook will be very useful. You might also want to look at an alternate solution - an external monitor that the P3 and the MacBook Air can feed. While this solution means that you can only see one or the other video sources at a time, it might actually be less expensive.
