February MARC Meeting by: w4spa 2012-02-18 06:07:26
MARC members & friends,
The next MARC meeting will be held on Monday, February 20, 2012 at 7:00 PM. The meeting will be held in classroom A of the Central Alabama Red Cross, 5015 Woods Crossing Drive.
After a brief business meeting, we will listen to several disaster preparedness themed presentations. Mike Watkins, WX4AL, the ARRL AL district 4 emergency coordinator, will make a presentation about the Amateur Radio Emergency Service and its role in central Alabama. El Erby, the Montgomery county emergency coordinator will tell us about the local ARES situation and Otto Arnoscht, the central Alabama Skywarn, Alabama Emergency Net Golf (AENG) net manager will make a presentation about the Skywarn program and it assists the National Weather Service when severe weather happens.
I hope you will take a couple hours from your busy schedule to join me next Monday evening for what's sure to be an entertaining and informative meeting.
As always, many of us stop by Schlotzsky's around 5:30 - 6:00 for dinner and fellowship before the meeting.
73,
Scott Poole, W4SPA
President, Montgomery Amateur Radio Club

Local Youth To Demo Robot At Montgomery Hamfest by: kg4pnl 2006-11-09 11:53:38
The Montgomery Amateur Radio Club is proud to have
young members that are excited about electronics.
You will have the opportunity to meet some of them
at this years hamfest as they demonstrate a Robot
they have constructed as part of the
BEST program.
BEST (Boosting Engineering, Science, and Technology) is a non-profit, volunteer-based organization
whose mission is to inspire students to pursue
careers in engineering, science, and technology
through participation in a sports-like, science
and engineering-based robotics competition.
Arriving around 10:00am, we have asked the
students to attend the ARRL Youth Forum. Their demo will take place soon thereafter.

  Digital Satellite?: Digital Satellite? (kg4pnl)

Digital Satellite? by: kg4pnl 2007-07-05 09:06:19
Since Icom introduced D-Star to the US market, (or at lease since I heard about it) I have been intrigued. In the beginning I wanted to know more about it, I wanted to know why I would want to pay more for a radio that just converted my voice to 1's and 0's. This conversation has has occurred many times on this site so I won't continue to tell what all I found out and why I purchased my D-Star radios.
During my research I read EVERYWHERE that D-Star, due to it's digitally modulated signal, could not be propagated through a standard analog repeater. Meaning, i couldn't use our 146.920 repeater to extend my digital communications. However a couple of days ago I read an article on the AO-27 website (http://www.ao27.org/AO27/index.shtml) where Robin Cutshaw, AA4RC made a contact over this satellite using two D-Star radios in Digital Voice Mode.
HMM, if standard, modern analog repeaters cannot pass the required information, how does this bird (launched in September of 1993) do it? I was surprised to find out that the radios on-board the satellite where designed to pass 1200-19200 baud GMSK data. Wow, GMSK, yeah that is what D-Star uses. That explains it now LOL.
Michael, N3UC who wrote the article explains a little deeper but reminds others who wish to make D-Star contacts via satellite to check with the control operators of the satellite before doing so. Good idea since only these digital radios can decode the signals and D-Star sounds like a harsh digital signal to the analog users operating that bird.
Digital Voice is being used in the HF Bands, as well as the world above 50MHz. Since this contact on July 1st we now know it can be used for working satellites too.
Chalk up another way to use Digital Voice!

  To Be Commended: To Be Commended (kg4pnl)

To Be Commended by: kg4pnl 2006-04-11 11:05:16
The progression of our hobby is dependant on new blood, as well as continued
interest in the different aspects of amateur radio. I consider myself
lucky to be surrounded by amateurs who not only see the importance of this, but step up to the plate to do something about it.
You see it in the meetings where different modes are demonstrated to introduce
those of us who may not have known about them. It is evident at Field day
when amateurs come out of the wood work to help setup, operate and break
down. Last years rash of devastating hurricanes brought amateurs from
coast to coast to assist those in need while the members of the Montgomery
Amateur Radio Club provided local support and coordination.
Though everyone seems to pitch in and help out, I would like to commend two
individuals for their most recent efforts in not only bringing new amateurs to
the hobby, but for helping others progress in their licensure. WB5NMZ and W4SPA
enthusiastically began instruction of the General Class theory and Morse Code
tutoring on the 2nd of March. The interest in the class was far more than
I expected, nearly filling the classroom with students and even some amateurs
already possessing the privileges wanting to audit the class and refresh their
memory of the rules, theories, and best practices.
I (KG4PNL) took the class mainly to be able to assist during
disaster relief efforts. HF honestly didn't interest me, with so much
unexplored in the Technician band plan, the only lure was the ability handle
much needed traffic during times of a disaster. During the class, I began to see
facets of HF I had not considered. Scott and Mark were not only able to
give us the tools to pass the exam, they brought a perspective of the
General class privileges that excited me.
Beginning Thursday April 13th, these same two Elmers begin instructing a
Technician Class License Course and have managed to nearly fill the classroom
with students that will be new to the hobby. There is a number of young
students which is very promising.
A huge Thank You goes out to Mark and Scott for doing such a great
job!

  2006 JOTA / JOTI: 2006 JOTA / JOTI (kg4pnl)

2006 JOTA / JOTI by: kg4pnl 2006-08-07 09:49:31
School is back for 2006 and this means that JOTA / JOTI is not too far around the corner. "When?" might you ask, well I am glad you asked!
Mark your calendar for October 22, 2006. We are working with the scouts on the location and we will let you know as soon as one has been established.
If you particpated last year, Several troops/packs came out and made their first amateur radio contacts. They talked to scouts both in the USA and some in other countries. M.A.R.C. members were on hand to help out and we were able to stretch the wings of our Emergency Communications trailer.
What is the Jamboree-On-The-Air?
The JOTA is an annual event in which about 500,000 Scouts and Guides all over the world make contacts with
each other by means of amateur radio. Short-wave radio signals carry their voices to virtually any corner of the
world. It's the shear excitement of having a live conversation with a fellow Scout or Guide at some other place
in the world that attracts so many youngsters to this event. JOTA is a real Jamboree during which Scouting experiences
are exchanged and ideas are shared. It’s a unique opportunity for each individual Scout to get the
real feeling of belonging to a world-wide movement.
What is the Jamboree-On-The-Internet?
Similarly to the JOTA, the Jamboree On The Internet connects Scouts using Internet techniques. The JOTI is a
separate event, but held on the same weekend as the Jamboree-On-the-Air. Units can choose to take part in either
one event or both.
World-wide
The JOTA and JOTI are world-wide events. During the weekend, units may participate for 48 hours or any part
thereof, from Saturday 00.00 h until Sunday 24.00 h local time.
Both JOTA and JOTI are WOSM events to which members of the World Association of Girl Guides and Girl
Scouts (WAGGGS) are kindly invited to take part and enjoy the international atmosphere together with the
Scouts.

Amateur Radio, a Dieing Hobby? Think Again... by: kg4pnl 2007-08-16 16:10:24
We have heard many times that Amateur Radio could be a dieing hobby. Falling second to Cell Phones and other technology is always a concern, we MUST keep on top of new technologies if we are to keep/gain interest with the younger crowd. However the numbers show a favorable rise in licensees.
If you look at a snap shot of January 1st through July 31st of this year and compare the same from last year, we are seeing GREAT things!
| | 2006 Jan 1 –Jul 31 | 2007 Jan 1 –Jul 31 |
| New Technicians | 12,268 | 15,549 |
| New/Upgrade Generals | 2,384 | 15,730 |
| New/Upgrade Extras | 1,909 | 4,284 |
Undoubtedly the abolition of the Code Requirement has effected the numbers, but I also attribute the rise in licenses/upgrades with new technologies such as D-Star and the important role amateur radio has played during recent natural disasters.
We have gotten a ton of great press over what we did during Hurricane Katrina, I see more schools getting involved around the country exposing the students to the science and fun the hobby brings.
Help keep the great momentum going, talk to your friends, schools, and co-workers. Let's let everyone know what a great hobby we have.

National Hurricane Awareness Week - Take Action by: kg4pnl 2006-05-25 13:21:47
If you are HURRICANE
AWARE you will be able to answer these three questions:
1. What are the Hurricane
Hazards?
Storm Surge,
Marine Hazards,
Tornadoes,
High Winds, and
Inland Flooding
2. What does it mean to
you?
Do you live in a Surge Zone? On a Barrier Island? In an area prone to flooding?
In a strong sturdy home?
3. What actions should
you take to be prepared?
Family
Disaster Plan,
Disaster Supply Kit,
Secure your home,
Have a place to go, and Stay Aware
Be sure to ask other
family memebers, friends and neighbors if they are HURRICANE AWARE too.
| TAKING
ACTION is as easy as 1-2-3:
|
|
Before Hurricane Season
Starts YOU SHOULD:
|
|
|
Assemble
your Disaster
Supply Kit.
These
items are often scattered around your home and simply need to be brought
together into one location. |
|
|
Write
out your Family
Disaster Plan.
Discuss
the possible hazards with your family. Determine if you are in an evacuation
area. Identify an out-of-town family contact. |
|
|
When a Hurricane Watch
is issued YOU SHOULD:
|
|
|
Check
your Disaster
Supply Kit.
Make sure
nothing is missing. Determine if there is anything you need to supplement your
kit. Replenish your water. |
|
|
Activate
your Family Disaster Plan.
Protective
measures should be initiated, especially those actions that require extra time
(for example, securing a boat or leaving a barrier island). |
|
|
When a
Hurricane Warning is issued YOU SHOULD:
|
|
|
Ready
your Disaster Supply Kit for use.
If you need to
evacuate, you should bring your Supply Kit with you. |
|
|
Use
your Family Disaster Plan.
Your
family should be in the process of completing protective actions and deciding
the safest location to be during the storm. |

SOB V Launch a Big Success! by: w4spa 2008-09-09 11:01:35
The launch and recovery of SOB V was a hugh success! Many thanks to everyone that helped out in any way. We couldn't have done it without all the assistance. Launch occured at 7:05 AM local time from KV4AC's QTH. The balloon rose slowly and silently into the morning sky. About 2 minutes after launch Tom, WB8COX, called on the radio to confirm he had the balloon icon on his laptop screen. This meant he was receiving and decoding the APRS signal from the balloon while in his truck in Tallassee. At that point, I felt like there was a real chance we were going to be successful... but only if the electronics on-board kept working. Around 7:30 AM Lamar, KC4LZO, called to report the predicted landing site. He had taken data from the NWS and run it through a software program that models balloon flights to arrive at a likely landing site. The prediction was for a landing near Tallassee... GREAT, I thought, we've already got chase teams in that area. For the next hour or so, we continued to watch the balloon icon on the computer screen move slowly East-north-eastward across 231, across I-85 all the time getting higher and higher... through 30,000 ft... 50,000 ft finally reaching 68,684 ft at burst. At this point it began falling and falling rapidly. At over 3,000 ft per minute my precious little box was plumetting back toward the Earth. Throughout the entire flight Bobby, N4AU, and Rik, KU4PY called out current location and ground track data to the chase teams. The 84 repeater was buzzing with activity as the chase teams coordinated their locations and directions of travel with one another. At this point, I could do nothing but wait and watch the telemetry numbers as they streamed across my computer screen. Where was it going to land was the big question.. and how hard was it going to hit the ground! Had the parachute gotten tangled and not opened? As the balloon got lower and into denser air, the parachute started to slow it's descent, what a releif! The chase teams began to close in on the likely landing site somewhere near Friendship. I could hear El, K4DJL, Mike, KB0OLA, Tom, WB8COX and Daniel, KE5GDK, Rodney, KJ4FPZ, and Dave, K5STL all talking about which turn to take to head toward the landing site. As the balloon made it's final descent to moved slightly more toward Rt 229 in Tallassee and finally came to rest in a small pine tree about 100 yards North of Ben Atkinson Motors... thank goodness it didn't hit a brand new car! All the flight hardware was completely intact and everything was still working. What a great flight! If you'd like to see the pictures taken from the payload, follow this link:

Thanks again to all that helped or listened. Stay tuned for details about SOB VI!

  SOB IX - ARHAB third place altitude record holder! (w4spa)
  Next SoB launch - Feb 7, 2009 9:00AM (ke5gdk)

SOB IX - ARHAB third place altitude record holder! by: w4spa 2009-08-01 22:16:09
The SOB IX flight was sponsored by the Montgomery Amateur Radio Club. The MARC purchased the expensive 3000 gram sounding balloon for the flight. In spite of having lost contact with the payload at an altitude of 122,457 ft, we did get APRS telemetry data back from it long enough to put us in third place on the altitude list!
The launch of SOB IX was right on schedule at 6:30 AM CDT on Saturday, August 1, 2009. We filled the balloon with hydrogen gas until it was pulling upward about 4 1/2 pounds. Then we attached the 35 oz payload to it and released it. It disappeared into some low clouds just a couple of minutes after launch. We continued to track the payload via APRS signals by using truck mounted decoding equipment and computers. The balloon drifted Eastward at around 15 mph until it reached an altitude of about 55,000 ft. Then, just South of Shorter, it made a "U" turn and traveled back to the West. It passed directly over the city of Montgomery still moving West. When it passed over the I65/I85 intersection, it was over 103,000 ft high and was beginning to pick up speed. While still continuing to ascend and increase in speed, it moved to the West of Montgomery, roughly paralleling Hwy 80. The speed continued to steadily increase, reaching a maximum of over 70 mph. After the balloon reached about 120,000 ft, the ascent rate really started to decrease. It was still going up, but getting slower and slower. We continued to wacth the telemetry data come into our our computers and cheered with each higher altitude report. Then without warning, at approximately 8:52 AM and an altitude of 122, 457 ft, it suddenly stopped transmitting. We continued to monitor the frequency, calling N4AU, KU4PY and W4FDD, who were recording the data at their respective home stations but they didn't hear it either. We called N4UZZ, KI4CSQ, K4DJL and KE5GDK who were downrange; but nothing from there either. Minutes went by without any additional transmissions. What had happened? Who knows. The payload is bright white and it's labeled with a weatherproof placard so hopefully someone will find it and send it home.
The SOB project will go on. We're already discussing the new payload. Stay tuned.. there's more to come.
On behalf of the entire SOB team, thanks for your continued interest in and support of our adventures!!
73,
--Scott

I have trouble remembering the format, so I thought I would post this here for all our amateurs with a newly aquired Element 1 CSCE.

Extremely strong signals |
Perfect tone, no trace of ripple or modulation of any kind |
Notes
Select the signal's most prominent characteristic from each of the R, S, and T
columns in the chart. Select the number from the R-S-T Numeral (left) column
which corresponds to each characteristic chosen. This R-S-T sequence of numbers
becomes the RST signal report.
If the signal has the characteristic stability of crystal control, the letter X
may be added to the end of the RST report. Use the the letter C to indicate a
chirp on the signal and the letter K for key clicks.
"RST is 599" - means that the morse code cw signal being assessed is Readability
5 (perfectly readable), Strength 9 (extremely strong signal), Tone
9 (perfect tone). This is the ultimate cw signal.
This reporting system may also be used for phone operation by leaving out the
Tone (T) portion of the report. For example, a signal of "5 9" means that the
phone signal is Readability 5, and Strength 9; a perfectly
readable and extremely strong signal. The term "S-9" is also used to report a Strength
9 for an extremely strong signal. If an S-Meter is being used as a basis of the
signal report, an S-9 is the numeric level of 9 (S-Units) on the meter.

Central Alabama Skywarn Extended Session Tracks Severe Weather by: w4spa 2011-04-16 18:21:52
By Otto Arnoscht, N4UZZ
Central AL Skywarn Net Manager
On April 15, 2011 a series of tornados and severe thunderstorms crossed our area, and Skywarn was in overdrive, tracking storms, gathering reports from the field, and forwarding severe reports to the National Weather Service. We had over 35 check-ins from the four counties (Autauga, Elmore, Lowndes, and Montgomery) and none of the counties were spared severe weather. We also assisted some traveling hams with weather condition reports as they were making their way through our area. The Skywarn controllers did yeoman’s work as the nets started near 3pm and ran all the way to midnight. N4BTB, W4EGR, N4UZZ, AK4FP, KR4JY, WA4BO, K4GDW, K4GR, KI4CSQ, K4LIA, K5VGU, KA4RRV and many others contributed to the Skywarn effort. >SKYWARN ACTIVITY / LOWNDES & BUTLER CO.
By Bob Overstreet, WA4BO Central AL Skywarn Net Controller Beginning on the afternoon of the recent storm, several stations in our area began reporting observations to the Central Alabama Skywarn Net, then up & running on the 146.84 repeater. Over a period of 3-4 hours, 3 stations sighted & reported the appearance of distinct “wall clouds” in the Fort Deposit area, as the storm rolled through. These sightings occurred during late afternoon. Specific times not recorded, locally. Total time observing & reporting was about 3 & ½ to 4 hours.
Stations & geographic locations:
1- WA4LR LARRY NORTH BUTLER CO. (approx 3 miles south & slightly west of Ft. D).
sighted wall cloud from his QTH, looking west, moving generally along hwy 185, from Greenville to Ft. D. Brief periods (5-10 min) of very heavy rain. Moderate to heavy rainfall throughout the rest of this time period. Station was operating from inside his home on an H.T., attempting to relay to the ’84 via the ’67.
2- WA4BO BOB SOUTHEAST LOWNDES CO. (approx 2 miles west of I-65
/ hwy 185 intersection). QTH is east central edge of town.
-sighted 2 distinct wall clouds during the period of observation (3-4 hrs). The first appeared at a cloud base due south of home QTH. Wall cloud was clearly visible thru a gap in tree line. The drop down from the cloud base was easily visible due to the contrast with the much lighter colored background. Also, the lower edge of this feature was a bit ragged, appearing as an occasional vertical column rotating very slowly around the center of the structure. Think maypoles. The second distinct wall cloud is believed to be the one described below in item #3, though viewed from the WEST side, at the QTH noted above.
3- KZ4J SPENCE SOUTHEAST LOWNDES CO. (approx 2 miles e/ne of the WQ4V CAROL intersection of U.S. 31 & Hwy 185, Logan, AL).
-sighted distinct wall cloud about 20 min after the first one reported in item 2. This wall cloud was noticeably larger, wider at the cloud base than (item 2). Extending one’s arm fully, palm upraised, it appeared 2 & ½ palm widths wide. General line of movement placed it just east of I-65, moving parallel to the interstate. Again the drop down feature was clearly distinct from the cloud base, due to contrast with the much lighter background shading. Neither station viewing this one ( viewed from both the east and the west) was able see any rotation.
