Unfortunately, for the next 7-8 weeks or so, I am going to have to bounce back and forth between living in Los Angeles , and living/working on a construction project outside of San Jose del Cabo, Baja Mexico.
  I can not commit enough time to keeping the feed up consistently, while being away from my home most of the week. Between internet issues, computer problems, stuck ATIS and many more issues, it just won't stay up by itself(unattended).

If anyone is able/interested in feeding KLAX in the interim, or for good, please step up. It is a great airport to monitor, and the people of this site deserve it.

Aw man, that's  a shame.

Thanks for hosting it for the time... hope to listen to it soon.

Thanks Rob for providing LAX. It was a pleasure listening to all the air traffic Los Angeles tower handles. I understand the maintenance of such feeds is sometimes difficult and your efforts were much appreciated! Good luck in your ventures!

I would love to host an LAX feed, but have not been able to get it working to my satisfaction.  I have what I think is a great location just north of 24R on Sepulveda Blvd., but the laptop I was using to test the feed just puts out too much noise.  Even without the laptop plugged in, the sound on my scanner is not nearly as nice as what Rob's feed sounded like.  An outdoor antenna and/or a different laptop would probably solve the problems, but I don't see any way to set up an outside antenna, and that laptop is all I have available.  We have very limited space in our store, so I need to keep the footprint as small as possible, while at the same time, the scanner needs to stay where it is, because we leave it on for our customers to hear.  I have tried a couple of homemade antennas with no significant improvement.

It could also be that my old Radio Shack scanner isn't doing so well any more.  Maybe someone could lend me a decent scanner that I could test with to see if that would help.

If anyone could step in with some technical advice and/or equipment, I'd be happy to give it another go.

I have a spare Uniden Bearcat BC350C that might as well be brand new that I'm willing to lend though I'm a bit uncomfortable giving something that cost me about $100 to a stranger on the internet  undecided

Well, I would feel the same, though the scanner that's now running the KBUR feed is one that was given to me by a friend I met on a DXing list and have never met in person  grin

At this point I am really just looking to test out another scanner to see if it would produce better results than the one I have, and maybe some help with antenna experimentation.  If the new scanner worked better, then maybe we could work something out.  I am not in a position myself to buy anything right now, but maybe Dave or other people interested in the LAX feed could help out.

Brian, get your hands on an old Radio Shack PRO-136, best airband receiver out there, and less than $100 bucks! out-performs the more expensive scanners in selectivity and sensitivity on aircraft, Uniden built it for Radio Shack and it's hotter than heck for aircraft.   Just build a simple 1/2 wave dipole will work best, 22 inches on each element.  No balun needed if you use 75 ohm coax (such as RG6 Quad Satellite Coax.)  You have a great location, you can do it!

I would love to host an LAX feed, but have not been able to get it working to my satisfaction.  I have what I think is a great location just north of 24R on Sepulveda Blvd., but the laptop I was using to test the feed just puts out too much noise.  Even without the laptop plugged in, the sound on my scanner is not nearly as nice as what Rob's feed sounded like.  An outdoor antenna and/or a different laptop would probably solve the problems, but I don't see any way to set up an outside antenna, and that laptop is all I have available.  We have very limited space in our store, so I need to keep the footprint as small as possible, while at the same time, the scanner needs to stay where it is, because we leave it on for our customers to hear.  I have tried a couple of homemade antennas with no significant improvement.

I have actually had 2 offers of scanners, as well as some cash and advice.  I also managed to dig up another PC that I can use, the same kind I'm using at KBUR.  This will work much better than the laptop that was putting out too much noise.  This is not a project that will be completed imminently, but the resources are coming together, so we will give it our best shot.

Our store is rather small, and despite the great location near the airport, it will be a challenge to figure out where to put everything so that it is out of the way, but still works well.

I will try to keep everyone informed of my progress.

Here is the latest update on KLAX:

Yesterday I received a scanner from Rob, so last night I went out to the store to try a few things.  I hooked everything up and the results were not appreciably different from my Radio Shack scanner.  The sound is ok, but there is definitely a fair amount of static in the background of most transmissions.  Listening to this right out of the scanner is not so bad, but in my experience, when you have that level of noise, the compression artifacts will make the feed sound pretty lousy.  I wandered around the store, plugging the scanner in to various outlets (while hooked up to the whip), and the results were pretty uniform.

On the plus side, I brought in the PC that I had set up, and powered it up next to the scanners.  It did not add to the noise, unlike the laptop I was using before, which made things unlistenable.

I tried a few things antenna-wise.  First I tried my twinlead J-Pole.  This antenna simply doesn't work well.  I switched to the small telescoping whip we currently use on our Radio Shack scanner, and it worked better than the J-Pole (though still not great).  Obviously I did something wrong when I made that thing.

I brought my homemade ground-plane antenna with me, but unfortunately the main element broke off when I put it in the car, so I was not able to try it out (well, actually I did try it, but the result was the equivalent of no antenna, which was not unexpected).  Incidentally, as I was heading out the door with the ground-plane antenna, my wife made it quite clear that she did not want that thing in the store.  Aside from the fact that she runs the store, so she does get to make such decisions, she really is right in that we do not have any place to put it - even if it does work well.  Last time I tried it with the Radio Shack, it wasn't much better than the whip.

So here is the bottom line.  I can try feeding what I am able to receive, but I don't think it will sound nearly as good as what Rob was getting.  Of course, something is better than nothing, so we can go forward and see how everyone likes what they hear.  I am starting to believe that our store may as well be a faraday cage.  The windows are all covered with metallic film, and the walls are red brick (likely with rebar embedded inside).  If anyone can recommend an antenna that can be easily hidden, but can pull in the signals better than what we have now, then I'd love to hear about it.  I guess I am really surprised at how little difference my two homemade antennas made compared to the whip.  Now that I know where Rob lives, I am really surprised that he had such a great sounding feed when I am probably 2 miles closer to the airport, and can't get it to sound nearly as good.

Any antenna advice is welcome.

Hey Brian,

Please refresh my memory. You can't put an antenna outside or on the roof? Would the store next door be willing to help with that?

We are on the ground floor of a 2 story building.  There is no easy way to put up an external antenna.

For the best signal to noise ratio, an external antenna will be your best bet. There are aviation antennas out there like the indoor antenna by DPD Productions; http://www.dpdproductions.com/page_vhf_air.html#vhfairblade
but I'm guessing if a signal is weak to begin with, such as inside a room, it's not going to improve things very much? You can try walking around the room with your radio in one hand and your antenna in the other and try to find the "sweet spot", but often times it may not be in the most desirable location?

One technique I use for antenna placement and alignment is to monitor ATIS, since it's constantly broadcasting and watch the signal level meter or listen for the best audible signal thru earphones. Just experiment. smiley

Good luck on your quest for good reception!

Brian,
  At this point I'm convinced it's just merely your inside location/antenna.

Do you have a wifi connection at your shop?  How about taking your laptop outside and using a hand held scanner, just stand out on the sidewalk. I bet your reception will be MUCH better. I think line of site and a good outside antenna are critical.

Now as to the outside antenna..Huh  Tough situation. Too bad you aren't closer to the Melody. They have ton's of satellite dish's and antenna on their roof.
