General Radio Information and Use Tips |
Thanks to Jeff Morgan for pulling this stuff together and allowing me to not only steal it, but bend the tar out of it ....
So you are gonna take a radio flying with you:
Radio with proper antenna(s). Some pilots carry an extra long one for out landings.
Your Radio Manual with your flight gear.
Charged Spare Radio Battery - or spare battery pack that takes AA's. (Optional, but a good idea.)
PTT (Push to Talk Finger Switch and Helmet headphone/speaker system)
Car Charger (Keep in vehicle - charge on the way if necessary, or just top off. It is better to have some charge than none at all...)
Cell Phone
Minimum
Tasks you should be able to perform on your radio:
Manual entry of a new frequency.
How to set tone squelch.
How to change between high and low power
transmission.
CTCSS, PL, Tone Squelch
Long
ago and not so far away, Motorola came up with a way to get more than one Land
Mobile customer on the same frequency at almost the same time. They figured that
different customers could coexist on the same frequency if they did not have to
listen to each other routinely. They invented Continuous Tone Coded Squelch
System or CTCSS for short and patented it as "PL" short for
"Private line". Other manufacturers, finding that the system was
absolutely necessary to stay competitive came up with "Channel Guard,"
"Quiet Channel," "Call Guard," and many other names for the
same thing to avoid lawsuits for marketing a patented system.
The
manufacturers of amateur equipment seem to have settled on "tone" for
encode only and "tone squelch" for encode/decode. Most of the
amateur VHF and UHF equipment manufactured in the last ten years has at least
encode capability (standard or optional) and many have decode capability
(standard or optional).
CTCSS
does not alleviate RF interference. If two FM signals are on the same frequency
at the same time, there will still be a heterodyne or beat note (unless one is 6
dB stronger than the other). But if CTCSS is being utilized and both systems use
different CTCSS tones, they will not have to listen to the other system's
traffic.
This
is an example of a Tone Chart found in a HT radio setting manual:

Everyone will be on the same frequency for
the most part. This offers us the best chance of receiving last minute reports
as pilots land and best chance of using pilots who are in the air to relay
messages to drivers etc.
Say your name, glider and color, altitude, distance from the tow road (via GPS)
heading and intentions. For example; "Chris on a white Gangster at 10'500, 10
miles out heading North East".
Don't come on and say, "Does anyone copy?" Just say what's on your mind.
Sometimes you have to say things twice, so you might as well start by saying it
once and pick up the pieces from there.
If you are giving conditions reports then be scientific. For example; "I am
topping out at 10.500; thermals up to 1500 feet per minute, gliding down to
1000 agl in between thermals."
If you are sinking out, your final transmission should happen at about 500 feet
minimum. Say, name, position, landmarks, intentions and then say your name again
along with the color of your glider. For example: "This is Chris on the white
Gangster landing at twenty miles out on a significant paved road right near a
farm house with a windmill next to it, this is Chris on the White Gangster."
Check in after you land and coil up your glider. A glider that is laid out means
that you need help.
After you land, if you have cell phone coverage, check in with 'the base' at
a number to be decided. If you don't check in, we will look for you
until we find you. No cell phone, stop at a farm house, borrow a phone, have
some cash.
Land near significant landmarks so that it will be easy for drivers to find you.
Keep your radios on low power until you land and then increase to full power
after you land if you have trouble communicating.
Land with other people
Follow roads; all these things lend to an easy and quick retrieve that can yield
you additional flights and more camaraderie.
Drivers please have a cell phone, GPS, compass and a radio with a charger. Did
you know that in order for a 2 meter radio to best communicate with another, the
respective antennas need to be at similar angles? Announce your name, vehicle
type, position and intentions on a regular basis. To identify yourself, you can
go down a dirt road and stop, sideways in the road. Pilots may be able to see
where you are via this technique. Don't be afraid to do some donuts in the
dirt to show wind direction or to help convey your position. Announce landmarks
as you see them. For example; "This is Donnne Doo Dah in the Red Gremlin,
going east bound on highway 69. A semi truck just passed me going the other way.
It's the only vehicle I've seen out here. There's a silo on my right and I
am going to pull over and light a tire on fire so that you know where I
am."
If people sound faint on the radio, then they might be far away. If they are
loud, they may be on the ground. If you think that you are close to someone,
honk your horn and see if they can hear it. Pay attention to the people who are
getting low in funny places away from the road. If they are landing near
pavement or they are still high, then you ought to pay attention to others who
are in more desperate situations. Call the 'base' phone number that we
designate on a regular basis, say what town you are in, which pilots are with
you etc. Have a note pad and write down some position reports as you hear them
on the radio. The general plan is; if it is early in the AM or late in the PM
and you are picking up people who are close to the tow road, then bring them
back to the tow road fairly quickly. If it is the middle of the day, at least
one drivers plan will be to follow the pilot who goes the farthest and pick up
the rest on the way back. Pilots, keep this in mind. There will be other
vehicles that will do shorter retrieves.
