It's time for Plano Balloon Festival again, and that brings me back around to the subject of digital video and images. For the past several years, we've...
... Sorry Mark, just saw your msg. We perform a safety backup function for the balloon flights during the 3 day event. We have two operations, one at the...
John: I know you said early in your message that you'd rather not use an implementation that requires dedicated PCs (& their associated batteries), but if you...
I've seen that. It looks like a nifty way to use that camera. Not suitable for this application, but great in the way you described. Now, it may be practical...
Picked up a HAVA Platinum HD at Frys over the weekend. Got the platinum because it provides DVR functionality. Finally got it hooked up, and yes, it does work...
Nope. Good point. It has component video I/O though. I seem to recall that the HDMI interface has a built in mechanism to prevent copying, and since the...
I was wondering about the following technical problem involving 802.11b/g and satellite downlinks in the 2.4GHz band: I want to setup an 802.11b/g HSMM...
These are good questions, but before I even try to answer them, how about these question?: If you know the satellite operator within short ground wave range of...
PS - The majority of Part 15 operation is on Channel 6 (80%?). It is the default channel for Linksys and many other APs. About 10% are defaults to Channel...
So John, where can we find these inexpensive passband filters on 2.4 gig? The ones I have seen have been in the several hundred dollar category. (Yes I know I...
Randy, Well, it is only really needed when using a BDA because the sidebands are stronger too, of course. I want to write that I saw them at FAB Corp, but I...
I've been working on a portable tower for ARES and public service work, and am getting close to the point of installing and integrating the on-board radio and...
... How far do you want to go? 2.4GHz is pretty much line of sight and trees and buildings block it. So height is the key. We used 15 db antennas, but also...
... I guess I missed what you were trying to accomplish with the "local" systems. What range are you trying for and how much are you planning to spend per node...

... Sold openly does not insure adherence to FCC rules and regs. :-) Since this is a part 15 device, you have to follow part 15 rules to keep it as such. You...

Excellent time for a Garage Sale of this stuff! The Lone Star DX Association quarterly luncheon is also this Saturday in Arlington. Hummmm? Buy a 5 element 20...
If you are going to use a dish or yagi, that means you are going point-to-point. The higher the gain, the narrower the beam width. And the narrower the...
The beam will be mounted to the side of a triangular tower section.. probably at one of the corners, with a home-brew azimuth rotator for getting it pointed...
We were at Inks Lake SP this last weekend and was hoping to take advantage of their free wifi. My ever so wonderful HP card didn't do so well. I almost had to...
Jerry, My recommendation is to get a USB type device with a cable and then put the antenna in the window. You can move it around that way and also use an...
Jerry, One thing to keep in mind is that you not only need to be able to hear the access point you are trying to connect to but the access point must also be...
