*Welcome to Handiham World.*Being thankful
[image: Cornucopia spilling out fruit - and a handheld radio!]
At Handihams, we have many people to thank for their support.
We have our volunteers, our donors, our members who progress through their
licensing classes, and long-time members who enjoy getting on the air. We
have our radio campers and enthusiastic net participants. Then there are
the early adopters who ferret out new technologies and share news about
them with the rest of us.
Volunteers have always been key to keeping the program running. In fact,
the Handiham System was first and foremost a volunteer effort from the very
beginning. Today we run it with just a small paid staff (me and Nancy) and
the facilities and infrastructure of our parent organization, Courage
Center. This is particularly important right now because of our big move
from the Courage Center Camping Department to the Courage Center
Community-Based Services. And by "move" I don't mean that we just changed
the organizational chart. We actually did move the Handiham System clear
back from Camp Courage at Maple Lake, Minnesota to Courage Center in Golden
Valley, Minnesota, 50 miles to the east. If you have ever moved an office,
you have an inkling of what is involved. You have to sort, file, pack, and
pitch. Boxes pile up. Decisions must be made. Logistical planning goes on
for weeks. Eventually moving day comes and so does the moving crew.
The whole process takes a lot of time and effort, but do you know what?
Our services pretty much kept up with the usual delivery schedule, even
through the move!
That would never have been possible without your help.
-
Our volunteer readers, especially Bob Zeida, N1BLF, and Ken Padgitt,
W9MJY, stuck to their recording schedule so that we could get our magazine
digests out to members in a timely manner. Bob stepped up to the plate and
helped me with QST, assuring that our blind members would get their Digital
NLS Daisy cartridges in spite of the move.
-
Our Net Advisory group and net control operators took charge of the
daily net and kept it on the air.
-
The Remote Base Software group kept working on the testing process
behind the scenes, and Jose, KK4JZX, continued the refinement process of
the next software release.
-
ARRL and CQ Communications continued to refer prospective members to us
and to help us get our message out.
-
The Stillwater (MN) Amateur Radio Association (SARA) assists with the
equipment program, which is undergoing a complete revision.
It was great to have all this help while we took care of the big move. Of
course there will be plenty more to do as we move forward into the new
year, but we will continue to deliver our audio lectures, weekly podcasts
and e-letters, and other services as we have done in the past year. The
remote base stations should be working better than ever when the new
software is available, and the equipment program should be up and running
once again.
We are thankful indeed!

Camp Courage & Courage North are part of a new camp organization
[image: Dining hall at Courage North, South entrance]
Courage Center Camps and Friendship Ventures are partnering to create a new
camp organization to serve people with disabilities, effective Nov. 19,
2012. The new organization will be called “Camps of Courage and Friendship”
until a formal name study is completed in 2013. Campers, volunteers and
staff will see traditional programs continue in 2013. Behind the scenes,
new methods and approaches will be developed to incorporate the strengths
of both organizations.
Learn more at:
www.campscouragefriendship.org
Handiham Radio Camp is tentatively scheduled for the Woodland campus, Camp
Courage in late July and early August. No pricing has been set, but
tentative dates are July 28 - August 2, 2013. That would make travel days
Sunday and Friday.
------------------------------
Handiham System is part of Community-Based Services
*[image: Cartoon showing people of different sizes, colors, and abilities

*The Courage Center Handiham System is now one of Courage Center's
Community-Based Services. It had been a part of Courage Camps until
October, 2012.*
In addition to inpatient and outpatient medical rehabilitation services,
Courage Center offers a number of services that support life in the
community for people with disabilities or complex health conditions. Some
of these services are actually provided in a community setting, others are
based at one or more of our locations. The Handiham System is one of these
programs that is available anywhere, thanks to web-based online delivery of
many services. It has members worldwide.
We look forward to continuing our Handiham services as part of this new
Courage Center organizational structure.

Gord, VA3WXA, writes about weather radio:
Hi folks. This is Gord VA3WXA. I have been a ham for three years and I have
been blind all my life.
I have had an interest in weather and Weather Radio since I was in my
mid-teens. It has been one of my main points of conversation during QSOs on
various repeaters and nets that I have checked into.
Last fall, I started up a Weather Radio Listeners Newsletter which is
issued quarterly in: February, May, August and November. It is available by
email distribution and on various websites that I have become affiliated
with over the past few months.
Late this past Spring I have also started up a net devoted to Weather Radio
and it has been going quite well, with an average number of check ins
around 20 per week. We meet at 6:00 PM CT on IRLP reflector 9034 and it is
mainly a check in net. We have also had guest speakers on with us,
primarily from Environment Canada. These have been selected by myself and
others on the mailing list to educate others about Weather Radio and to
allow questions to be put forth and answered.
In case you don't know what Weather Radio is, it's a VHF broadcast service
provided by both Environment Canada and the U.S. National Weather Service
to the general populace to inform of current weather conditions and
impending weather emergencies. Environment Canada broadcasts these signals
across the nation twenty four hours a day, seven days a week in both
English and French in Canada, and primarily in English in the US, however
it can be heard in both English and Spanish on some stations. It can be
heard on the following frequencies (in MHz): 162.400, 162.425, 162.450,
162.475, 162.500, 162.525, 162.550. With about ninety percent of the
population living within range of a Weather Radio transmitter, most of us
can hear the broadcasts. In some selected areas, the reports and warnings
are also broadcast on the regular AM and FM bands. Of course you need a
radio that can hear the signal and there are specific receivers made
strictly to listen to weather radio transmissions. But with most of today's
amateur rigs having wide frequency receive capabilities, most of us can
hear these broadcasts on our handheld, mobile, and base two meter radios.
One of the nice things about this service is that you can hear more than
just weather information on these broadcasts. Weather Radio is an
all-hazards alert system that will provide information and warnings on a
variety of situations that include blizzards, hurricanes, thunderstorms,
tornados, tsunamis, biohazards, child abductions, civil emergencies,
chemical hazards, contagious diseases, earthquakes, nuclear events, and
many others. As you can tell, it would be very beneficial for every ham to
monitor one of these frequencies. However, the sweetest thing about Weather
Radio is not just the warnings and information. It's also about the way
these warnings can be heard. Using a receiver designed to mute the audio
until it detects a specific tone or stream of digital information sent
along with the broadcast signal, you don't even have to listen to the
actual transmission audio at all. There are two ways to do this. All
warnings are preceded by a 1050 Hz tone. When a weather radio or other type
of receiver that has this tone feature detects the tone, the squelch will
open so the warning broadcast can be heard. This is very similar to our
CTCSS or DCS tones and codes that are used to access repeaters or turn the
audio on for a receiving rig. The more modern method now in use is called
SAME, or Specific Area Message Encoding. Using digital signals in the
broadcasts and a SAME enabled receiver, you not only can set the specific
areas of any warnings or alerts to be notified of, but also what type of
alert to be notified of. This means your receiver will monitor the signal
in silence, but then blast a loud warning tone when a specific alert for
your specifically chosen area or areas are transmitted. You will then hear
the audio of the signal. As an example, if you have a SAME-enabled receiver
and live in Toronto Ontario, you might program your radio to listen only to
warnings that affect the city of Toronto only. Any warnings for any other
areas are ignored, unless you are like me and leave your SAME radios on the
ALL COUNTY feature. As well, you could set up the receiver so you only hear
alerts regarding child abductions, earthquakes, and contagious diseases. If
a hurricane is heading your way though, you would not be notified of it.
Regardless, the SAME feature is quite versatile in letting you tailor the
warnings for your own interests or requirements. Many ham rigs have the
1050 Hz tone enabled as an option if you chose to scan the weather radio
frequencies. The squelch will open when the tone is detected so you can
hear the alert broadcast. You can also buy separate older weather
radio-specific receivers with the 1050 Hz tone, or newer receivers that are
SAME enabled. For instance, my Yaesu FT60R handheld not only comes with the
weather frequencies already programmed in, but if you select the WX alert
option, during any type of scan activity the radio will scan the weather
frequencies and will stop and open the squelch if the alert tone is heard.
My Uniden BC346T trunking scanner will open the squelch when both a tone
alert or a programmed SAME message is broadcast for the area that I select.
Tests of the warning system are conducted on a regular basis so listeners
can test their receivers. SAME tests in Canada are done around noon every
Wednesday and the basic tone alert is done around noon on the first
Wednesday of each month. In the US, tests of both SAME and the tone alert
are done between 9:00 AM and noon on Wednesdays. There are some stations
that do tests on Tuesday evenings though. I found that out while going on
YouTube . Grab a listen and see what Weather Radio has for you. For more
information visit the following websites http://www.ec.gc.ca/weatheradio,
or go to www.nws.noaa.gov/nwr.
If you would like to join my mailing list you can send me an email at
blindgordie@xxxxxxxxx and I will send you your own copy of all the
newsletters that have been issued so far. I also send out monthly reports
with other information that may or may not appear in the next issue.
As a fellow white caner I feel Weather Radio is a very important tool for
us to use to keep informed about up coming weather, whether it is just the
forecast or severe weather. I hope to hear from you if there is an interest
in this service.
73, Gord

*A dip in the pool*
It's time to test our knowledge by taking a dip in the pool - the question
pool, that is!
Let's go to the Extra Class pool, and this time we are going to pretend
that we are shopping for a new receiver. Its specs mention "noise figure".
E4C08 asks, *How might lowering the noise figure affect receiver
performance?*
Possible answers are:
A. It would reduce the signal to noise ratio
B. It would improve weak signal sensitivity
C. It would reduce bandwidth
D. It would increase bandwidth
Okay, so do you want a receiver with a lower noise figure or one with a
higher noise figure? Let's go to the bookshelf and pull down our letter
"N" encyclopedia so that we can look up "noise figure".
Ha, ha, of course we don't have a set of old encyclopedias. Instead we will
go to Wikipedia, which tells us:
*The noise figure is the difference in decibels (dB) between the noise
output of the actual receiver to the noise output of an “ideal” receiver
with the same overall gain and bandwidth when the receivers are connected
to matched sources at the standard noise temperature T0 (usually 290 K).*
Obviously We would all rush out to buy an "ideal receiver" if such a thing
were available. Hey, it would sure work great connected to an "isotropic
antenna"! But of course we all live in the real world, in which the active
components in our radio equipment are not perfect and hence add some
unwanted noise to the received signal. Careful engineering and high-quality
components can significantly reduce this unwanted noise. The "lower noise
figure" in receiver specs means that the receiver design reduces the
internally generated noise while not reducing the level of the signal being
received - and that's a good thing because we are then improving weak
signal sensitivity, answer B.

*Work continues on the remote base software. Both stations are accessible
via Echolink for receive. *Look for W0ZSW-L and W0EQO-L using the search
function in your Echolink application. Please note that it is not allowed
to connect through RF to the two remote base Echolink nodes, you can only
use the Echolink application of a computer or smartphone.

- *Echolink tip: Control the HF receiver frequency by typing it into
the text box. *Example: Get focus in the text box, then type 10 and
press the enter key. The receiver goes to WWV, 10 MHz. Type 14.3 and press
enter to go to the maritime mobile net on 20m. If the band seems dead, it
may be that someone else has used the radio on another band and the antenna
has not been tuned to the band you want to listen to. The antenna is only
tuned when a user logs in with the W4MQ software and transmits. The LDG
autotuner senses the RF and tunes.
If problems show up, please email handiham@xxxxxxxxxxxxxxxxxx

Golden Valley, MN 55422*
*Equipment change: *We no longer accept antennas, except small accessory
antennas for handheld radios.
*Please remember that the cassette tape digest ceases following the mailing
at the end of November! After that all audio is in DAISY digital format or
on line through the members only section of handiham.org. The Library of
Congress 4-track tape system will no longer be supported in any form after
2012. *
*Digital mailers are important: *If you do mail a digital cartridge to us,
please be sure that it is an approved free matter mailer. Otherwise it will
quickly cost us several dollars to package and mail out, which is more than
the cost of the mailer in the first place. We don't have a stock of
cartridges or mailers and not including a mailer will result in a long
delay getting your request back out to you.
*DAISY audio digests are available for our blind members who do not have
computers*, playable in your Library of Congress digital player. Handiham
members who use these players and who would prefer to receive a copy of the
monthly audio digests on the special Library of Congress digital cartridge
should send a blank cartridge to us in a cartridge mailer (no envelopes,
please), so that we can place the files on it and return it to you via free
matter postal mail. Your callsign should be on both the cartridge and the
mailer so that we can make sure we know who it's from. Blank cartridges and
mailers are available from APH, the American Printing House for the Blind,
Inc. <http://www.aph.org/>
