Ran across another ham tonight that wants to experiment with HSMM. We want to set up about a 40 mile link with a "repeater" in the middle on Iron mountain. My...
HI, I am Mark N5RFX and I live in Arlington and was wondering if there were any network diagrams that are available for Ham high speed networks? Is the...

I am using a WRT54GL with DD-WRT installed. When I went to Ebay to determine the current pricing of the WRT54GL, I came accross a unit with DD-WRT installed...

Sure contact John Beatles. <jbeadles @ pobox.com> (Remove spaces.) He just started a ntx_pse_pbf yahoo group for organizing the event. So far no messages but...
... Right, because 2.4GHz will be completely free and clear of all traffic except for all the ad-hoc networks deployed by the EOC, EMS, FD, PD, etc... -- Kris...
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...

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...

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...
