Welcome to the SVRC

September 25th, 2009


hank you for visiting the Sangamon Valley Radio Club! We are an organization of both licensed amateur radio operators and non-licensed individuals, based in Central Illinois, who are dedicated to preserving the spirit of this great hobby we call Ham Radio. We accomplish this through community service, technological proficiency, social activities and fun! If you are interested in amateur radio communications, if you are already a licensed amateur and want to meet other amateurs in the area or if you just like to have fun, the SVRC is the place for you! Please come join us at our next club meeting. Guests are always welcome. We also have an email list server hosted by Yahoo Groups. If you don’t already receive email announcements then you can sign up below to be added to the list. The SVRC is an ARRL affiliated club and maintains a working relationship with the Illinois Capital Area Chapter of the American Red Cross.

WWII Radio Author to Visit VFW Post 10302 on March 2, 2013

January 20th, 2013

Sangamon Valley Radio Club and VFW Post 10302 welcome Lisa Spahr, author of World War II Radio Heroes, to present a story from 

WWII that most never knew.

Bring the whole family – as this story will inspire, delight and warm hearts of every age. WWII Radio Heroes: Letters of Compassion is a story about strangers helping each other during a time of war. The book features more than 30 letters and postcards sent to the author’s family in 1943, alerting them of her grandfather’s capture and status as a prisoner of war. Upon discovering these letters, Ms. Spahr began researching the people who did this, and why, and reached out to find them or their next of kin, more than 60 years after the fact. Her journey is detailed in WWII Radio Heroes.

Field Day 2012

Field Day 2012 Report

Well, Field Day 2012 is behind us. To summarize, propagation was bad to non-existent. The weather was nice, with the exception of a very minor shower late Sunday morning. The Saturday night dinner was excellent, and the social hour was fun (as always).

Due to poor propagation, SVRC members worked diligently, trying to contact other FD stations. The solar website http:/dx.qsl.net/propagation indicated that FD weekend would be a period of ‘low solar activity’, and that prediction was certainly correct. Our raw QSO count for all five stations was approximately 700. Of course, our final score will be higher, due to points added by ARRL for various activities. For example, we will receive 100 points for copying the ARRL Field Day message.

Please remember that Field Day is not the product of any one person. A successful Field Day is a team effort. Needless to say, SVRC members provided teamwork plus a willingness to go the “extra mile”. No sooner than a task was identified than someone would volunteer to take care of the task.

Also, I would like to thank our sponsors, the Riverton Middle School for allowing us to use their facility, and Staab Battery for loaning the deep cycle batteries to power our stations. Staab has provided batteries for Field Day for the last 25 years (at least). Riverton Middle School has hosted us for the last six years (at least).

See you next year at Field Day 2013!

DX’ing resoures from WA9AQN presentation on 2/2/2012

February 4th, 2012

DX’ing Resources:

News – – this site has a summary of upcoming, ongoing and past dx operations ranging from the huge expeditions to casual vacation operations and links to more detailed websites of expeditions and operations:



“The Rules of the Antenna Game,” Ted Hart, W5QJR (1984)

This site promotes a book that contains a lot of very useful antenna guidance geared toward construction of very DX-effective antennas at very reasonable cost. There are a lot of expensive gimmicks in the antenna market that will not enhance your signal quality at the other end over some simple wire antennas. While the book isn’t free, the amount of money it will save you if you are thinking that the latest whiz-bang gimmick from the XYZ antenna company for $300 will give you a better signal far exceeds the cost:


Pileup behavior: these YouTube videos of screen shots of a software defined radio bandscope show the DX transmit frequency and the pileup running up the band, one of good pileup management,

and one of poor management

We will be having an optional gift exchange with a $25 limit. If you choose to participate we draw numbers for who gets to choose 1st. 2nd…..and the present can be stolen 3 times, we also have the rule that you can only steal 3 presents from the same person. It is always a lot of fun!

Accessing the W9DUA D-STAR Repeater

August 31st, 2011

The following information may be useful if you have a D-STAR capable radio and wish to access the new W9DUA D-STAR repeater.

The repeater transmits (and you listen) on 443.78125 MHz.

The transmit offset is +5.0 MHz.

Call sign programming information…

Note the “*” in the examples below indicate you should type a blank space, not the asterisk character. If you do not have the ‘B’ or ‘G’ in the eighth position of the field it will not work.

The exact methods for programming this information into your radio vary from model to model.

“MY CALL” should be set your FCC assigned call sign

“YOUR CALL” should be set to “CQCQCQ”

“RPT1″ should be set to “W9DUA**B”

“RPT2″ should be set to “W9DUA**G”

What does all of this do?

The “CQCQCQ” tells the system you want to communicate with anyone listening not just a specific station.

The “W9DUA  B” tells the repeater you want to use Port B, which is the UHF repeater module. Some D-STAR repeaters have VHF, UHF, and 1.2 GHz ports.

The “W9DUA  G” tells the repeater you want to also use the gateway to the rest of the D-STAR system. This allows DV-Dongle users to hear your transmissions as well as other users around the world who may be linked to our repeater.
