Feed Setup Pictures / Dongle location benefit
« Last post by ScannrbaseHRL on April 29, 2017, 11:48:15 AM »


 Im working on an Antenna setup for the scanner I want to use for the Valley approach and Harlingen Tower feed in South Texas
I have a 25 ft mast with a VHF 1/4 Wave antenna on top, I don't know much about how much of what the antenna is receiving gets lost
per feet of coax length or how much noise and interference is gained in a long coax but I imagine that the shorter the coax the better
so I thought what happens if I put the dongle inside an enclosure box directly under the antenna and run an active powered USB extension
all the way down to the PC or a Raspberry PI, the dongle enclosure box would be sealed with silicon to avoid any water or moisture to enter has anybody tried this before? are there ant drawbacks to this any input will be appreciated.

Feed Setup Pictures / Feed HOWTO
« Last post by mt6561 on April 29, 2017, 11:06:37 AM »
Hi!

I live near an airport and can set up a device to make a feed. Please point me to howto or just explain what should I buy and how to set up it?
I understand it can be SDR device with a sort of Raspberry PI, but is there any step-by-step manual or ready-to-use device which I just can buy and install on the roof?

Many thanks that comprehensive reply.

Geoff,
You are correct. For a fuel emergency, together with wind conditions which present a challenge for conventional gear (tailwheel) pilot, in an emergency the pilot-in-command is authorized to deviate from regulations as necessary for safety.
Quote
Title 14 of the Code of Federal Regulations (14 CFR) part 91, section 91.3 allows deviations from regulations during emergencies that allow the PIC to make the best decision to ensure safety of all personnel during these contingencies. Also, by declaring an emergency during flight, that aircraft becomes a priority to land safely. Pilots who become apprehensive for their safety for any reason should request assistance immediately.

REF: Part 91, A, Section 91.3

If the runways and corresponding taxiways C, D, Z and W were clear(ed), it appears that taxiway C is oriented more closely with surface wind from the southeast.
Taxiway C (between E and A) is not completely straight, but that aircraft type would not typically require other than a short landing roll-out (at a relatively low, ground speed).
Large/tundra tires help for landing on a paved/un-paved surfaces.

Thankfully what matters most: it appears that no one was injured and there was a safe outcome for the pilot.

Listener Forum / UHF Aviation Receiver & Analog Raster Scan Screensaver
« Last post by Tower Night Shift on April 27, 2017, 10:11:39 PM »
Hi all, newbie here, I never know planes had radios until I saw the Indianapolis Center scene in Close Encounters....Duh. Anywho I am getting back into aviation monitoring with a Uniden BC92XLT & a generic RTL stick since the mega bucks super scanners are reaching close to $500 with Florida pretty much 90% P2 blending with the more exotic digital modes jacking the prices up even more with the "Big E" close behind so time to move on :cry:. I searched the net & cannot find a decent commercial grade UHF aviation receiver that scans, any help would be greatly appreciated. Secondly is anybody aware of a decent quality raster scan ATC radar screensaver? Love the site. Thanks all & have a blessed weekend. :wink:

Story and news video http://www.kmov.com/story/35230825/emergency-crews-respond-to-plane-crash-at-spirit-of-st-louis-airport

'As there was no distress call made, authorities believe the plane suffered a hard landing.'

Whilst it seems the pilot did not declare an emergency, after making two unsuccessful attempts to land on runway 8L he told the controller he was worried about fuel and asked  if there was a a grass area where he could land in a more favorable direction. Permission was refused. Subsequently the aircraft made the very heavy landing on the runway and sustained significant damage. The pilot was lucky not to be injured. If he had declared an emergency would he have been able to insist on landing on the grass?  Should the controller have given him the opportunity? In short, could the situation have been dealt with differently?
