My only suggestion, FWIW, would be to rotate that antenna to horizontal or end-mount it from the handle if you want to stay with vertical polarization. Having the driven element right next to the mast is killing the gain and pattern, not to mention making any setting of that gamma match moot once mounted to the mast. Ideally you would pull that rubber handle off, add a foot or two of tubing and mount vertically with the reflector element at least a foot away from the mast. The coax from the driven element would then be strapped to the antenna boom, fed straight back to the mast and then down. Here's an example of the ideal mounting for vertical arrays:

The formation flight, it's pretty, but can the A350 not do barrel rolls?   grin


Neat vid Ron R!

martyj19, your comment reminds me of the public demo of the -80 prototype in Seattle, 1955...

Great setup! What kind of USB audio converter(blue box) used on KACY feed? Mind sharing with some technical info?

Thanks

Jeff-

We generally use one of the two audio interfaces on feeds that LiveATC helps with:

http://www.amazon.com/gp/product/B009NVS6KS/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

We also use the Griffin iMic - available from various sources.

One reason is that these cards have a proper Line In interface which presents the proper impedance to a scanner's audio output.  The other reason is that these cards have tested out pretty well in audio quality tests.

The cheap $1USD audio interfaces that exist can be made to work - you just have to either very tightly control the scanner volume so as not to overdrive them or provide your own impedance matching network so as not to overdrive the mic level input of those cards.

We don't know but are working on it.

Ok, just ordered the adapter. RadioShack had free 2 day shipping, so it should be here soon. I'm done with this semester of college, so now I have no excuses for the next month or so. I WILL get this done.

The KTVC feed is broadcasting only an automated observation weather station. Cannot hear anything else.

I just installed the new tower frequencies for KHDC (Hammond, LA).
They are 120.575 Tower
and 119.850 Ground.
I will email Dave the new information soon so he can change the
descriptions on the website.

You guys are the best.  Though I'm a tight budget I did make a tiny donation. Thank you
