Hi. I´m a student that is going for the PPL. I would like to listen the
traffic and controllers but i don´t know how.
I just bought a scanner MAycom AR108 but i does not catch the controller.
My question is:

- Does a handheld transceiber (jhp 500, icom 22 or so..) catch the
controller while in ground. (at home for example)..

One idea that came to me is to buy a used COM from an aircraft (cheap of
course) and mount it at home. DO you know where to get this old used COM or
NAV/COM at cheap price. (Do not tell my ebay).

Thanks in advance

If your scanner can't hear the controller, it's not likely that a transceiver will either.

You should first invest in a higher/better antenna.

It's all in the antenna.
Go to Jim Weir's website and you will find the plans for an excellent
external antenna you can build.

My vote's for higher. Back when the FCC tightened the frequency standards,
I replaced my Escort 110 with a newer radio. The Escort now sits in my
office, with a Rat Shack power supply and a copper-tape dipole antenna.
The ATIS for Sea-Tac International (about eight miles away, at about the
same ground elevation) is just *barely* unreadable. When it was in the
airplane, this radio with a similar dipole antenna used to pick up traffic
at an airport 80 miles away from pattern altitude.

The current setup does just fine for ground transmissions from a nearby
uncontrolled field, but then I'm only two miles away and 400 feet higher.

Keep in mind that VHF is line of sight. You should hear any transmission on
the frequence if your antenna has an unobstructed line of sight to the
transmitter. This is probably why you can hear (in flight) aircraft but not
(ground based) ATC.

VHF requires line of sight between the transmitter and receiver.. at ground
level and too far away.. or a hill in the way.. you will not hear the
controller side, only the airborne aircraft side..

In simple terms radios operate in line of sight. That's why it is difficult
to pick up transmissions from ground stations, whereas its straight forward
hearing to aircraft.

To hear ground stations you either need to be close to them on the ground or
in the air.

A bigger (higher) ariel will help.

This is true for the VHF frequencies used for conventional aircraft com
communications (118-136 MHz). HF frequencies (below around 5 MHz) bounce
off of the ionosphere and can be received well "over the horizon." That is
why HF is used for oceanic com.

Yes, picking up a distant VHF ground station while on the ground is
unlikely. Just how far away one can be and still get a usable signal
depends upon terrain and heights of antennas (at both ends).

MAYBE!!!


I have for some time thought that it would be neat if the FAA (or some other
institution), as a PR and educational initiative, put some selected ATC com
interchange on the web in real time streaming audio. Maybe a busy JFK
RAPCON frequency would be a good choice. ATC coms are public domain (i.e.
they are not protected as private communications) so their re-broadcast on
the Web would be perfectly legal.

This already exists. Landings.com has live ATC feeds from 8 or 10 different
locations (including JFK, MIA, ORD) that you can listen to using RealAudio.

LF = 30 - 300 kHz.
MF = 300 - 3000 kHz. / 3 MHz.
HF = 3 - 30 MHz.
VHF = 30 - 300 MHz.
UHF = 300 - 3000 MHz / 3 GHz.

and so on. Most everything from 30 MHz. on down will bounce off somewhere in
the sky at some point in time, not always perfectly predictable when and where.
