Title: KLAX Final App (North/South), in and out every few minutes
Post by: Stephen_A on February 21, 2017, 11:44:36 PM
Hi all,  I am new here.   :-)  My favorite feed is KLAX Final App (North/South) and have noticed for the last week it's been hit or miss.  Every few minutes it goes in and out with a squelch sound and then comes back for a few minutes.  Rinse and repeat.  What could be causing this?

Today it's worse, it sounds like the site lost the antenna.

And normally that could be due to poor visibility between the receiver and the antenna. But with METAR readings like:

KLAX 061553Z 35008KT 10SM FEW160 11/M02 A3020 RMK AO2 SLP225 T01111022 $

That shouldn't be happening (and it still is today, on 3/6). So I'm not sure as to what it could be.

I'm actually saying the opposite! :P

Let's take the highest point in that area: Mt. Wilson at roughly 6000ft, or even Mt. San Antonio, at 10000ft. If the METAR around that time is showing few clouds at 12000ft, you'd still have line of sight with the highest point (again, not taking the smog into account). The transmitter is definitely much closer to the feed site than that, so even with few clouds at 200ft, you'd still have some visibility. I've only seen a feed really take a hit with a BKN or OVC ceiling really low, or even VV001. FEW002 shouldn't cause that, let alone FEW120.

Dave will definitely sort it out.

The Final Approach feed is cutting in and out and I hear a lot of static, sometimes only picking up one arrival frequency.
