NEXT MEETING:  Monday Night, October 2nd, 2017
Location:  Western Sizzlin’ , 1916 Congo Road in Benton, Arkansas
Guest Speaker:  James D. Ferguson, N5LKE, Arkansas Section Manager,
Delta Division of the ARRL 

In keeping with our tradition, we try to have at least one meeting each year in Benton or Saline County.  At the October 2nd meeting, we will be fortunate to have our newly elected ARRL Arkansas Section Manager, J Ferguson, N5LKE, accept our invitation;  he is an enthusiastic and dynamic speaker.  He will speak to us about the importance of being involved in the ARRL and he will explain how one can actually become involved.  The ARRL needs the full support of every member of every amateur radio club they sanction.

We will also spend the usual 10 minutes on our annual election of officers.  If you would like to nominate someone to serve as a club officer, please contact past president, Randy Wright, AE5RW, to place your name in nomination.

At this meeting, we will receive an update on our DMR project from Michael Clay, AC5XV, our project manager for this new repeater installation.  We have purchased our new Motorola SL-5700 DMR repeater and have taken delivery.  We also have acquired a DB-408 UHF antenna.  That just leaves a few more items to be rounded up and then perhaps by the October 2nd meeting, our DMR repeater will be operational.  Also, it is never too late to contribute to the DMR repeater fund.  We began on April 3rd with a goal of $2500.00 and many of you pledged to contribute.  If you have not fulfilled your pledge, please bring cash or check on October 2nd, OR use the PayPal button at the top of this page.

Of course, don’t forget that the CAUHF Group has the best raffle prizes in all of amateur radio.  We will have a new Baofeng GT-3WP dual band, hand held radio plus four other nice prizes including some Craftsman tools and other items.

We will elect new officers for 2018 at the next meeting on Monday night, October 2nd.
Here is a list of our current officers.

President:  Steven Hicks, W5NLR
Vice President:  Sam Baldwin, N5SRB
Secretary-Treasurer:  Margie Wofford, KG5EPM (re-elected for a 2nd term)

Did You Miss It?  Our 3rd Quarter Meeting was held Monday Night, July 10th
Location:  Larry’s Pizza, 12911 Cantrell in Little Rock
Program for July 10th:  DMR Decision Day + Tim Leet, K5TEL on Cross Band Repeat

At last, we are ready to begin moving forward with the purchase of a new DMR repeater and get it on the air and linked into the world-wide Brandmeister System.  Our project manager for the new DMR Repeater is Michael Clay, AC5XV and he provided an overview of our “DMR Project”–including the brand and model we intend to purchase, along with the proposed location and frequency.  The frequency will likely be 444.600+ with no tone.

Because there is a DMR repeater on Shinall Mountain in Little Rock and another in Sherwood, it only makes sense for us to locate our repeater to the SOUTH to create more DMR coverage in central Arkansas.  We have a great site available just west of Benton on a high peak and Internet is available there.  This location will cover much of Saline and Garland Counties and well into south and central Little Rock.  Also, this will provide hand held coverage in Benton and most of the surrounding area.  Many of us have already purchased handheld DMR radios.  At the meeting, the members voted unanimously to purchase a new Motorola SLR 5700 repeater immediately.  We already have a UHF duplexer in stock along with some feed line and a used Andrews DB-408 antenna in pristine condition.  The CAUHF Group will be a contributor to the statewide, nationwide and worldwide Brandmeister DMR Network.  Donations have already begun coming in;  we are almost one-third of the way toward our $2500.00 goal.  Your donation goes toward the purchase of OUR repeater but in reality, you are also helping to build the entire Brandmeister network of DMR repeaters.

After the DMR discussion, Tim Leet, K5TEL, gave a brief presentation about the entire concept of cross band repeat.  It can be difficult to grasp the techniques in the beginning and mistakes might cause interference to nearby repeaters.  Therefore, it’s very important that all of us know what we’re doing before setting up cross band repeat using our handheld radios and mobile radios installed in our vehicles.  Tim thoroughly covered the proper way to setup a cross band repeater.  If you missed his presentation or have questions about this topic, you can contact Tim on the AR Links system, just about anytime–just call K5TEL and he will be happy to talk with you about cross band repeating.

As usual we raffled off some tremendous door prizes including a new Baofeng GT-3WP dual band, hand held radio plus four other prizes including some nice Craftsman tools and other items.  DON’T miss the fourth quarter meeting on Monday night, October 2nd, 2017.  The location and program will be posted here as soon as it’s available.  We WILL have a CAUHF Group Christmas Dinner again this year as last year’s event was well attended!

443.000 (100.0) Repeater Back on the Air in a New Home:
The
Plaza West Building near Markham & University

The 443.000+ (100.0) machine has been repaired and realigned by a Motorola Certified Technician and moved to the 12-story Plaza West Building, the second highest point in Little Rock.  The repair technician said the repeater is in remarkable shape.  This move was approved by the CAUHF Board on August 8, 2014.

Currently it is transmitting 32 watts on a temporary antenna until we can procure a high gain commercial antenna. Coverage could reach as far as Benton and Conway or about a 20 mile radius.

plaza_west_htThis repeater is the legendary Motorola MSF-5000 and it is NOT linked to the AR Links System. Use this repeater anytime you need LR/NLR Handie-Talkie coverage or you simply have no need to contact anyone on the AR Links System. The repair and re-location team for this project included Steven Hicks, W5NLR, Margie Wofford, KG5EPM and we were also assisted by a licensed electrician who holds a General Radio Operators License (GROL).

As stated above, the Motorola MSF-5000 is indeed a legendary repeater.  It’s reign spanned the era before and after the introduction of digital radios, from the early 1980’s until the mid-2000’s or about 25 years.  It was discontinued about 10 years ago and now, only used or surplus parts can be found.  Unfortunately, thousands of these (still working) repeaters have gone to scrap yards and landfills to make way for digital radios and repeaters.

Yet, hundreds of these solid state, analog repeaters–in many variations–still remain on 24 hour duty in small town police and fire departments across America and around the world.  Many remain in commercial service as well, dispatching plumbers, electricians and pest control operators to customer service calls.  It was undeniably, one of Motorola’s most successful, dependable and profitable products.  Only God knows how many thousands of lives and how many billions of dollars in property have been saved as the result of emergency communications routed through a Motorola MSF-5000.  We are fortunate to have this one collectors’ item, shined up, finely tuned and still serving those of us in amateur radio.     — W5NLR

Let’s All Get Together! 

baofeng_UV82For quite some time, we have considered establishing standard simplex frequencies for use within the CAUHF Group (and for anyone else who wishes to play along with us).  All of these frequencies fall within the ARRL Band Plan for VHF and UHF.  Here’s what we’ve come up with thus far.  We will not use PL tones on any simplex frequency (unless it becomes necessary in the future).  During special events, disaster drills, etc., we can refer to these as “tactical channels”.  Please program all of these simplex frequencies into your mobile radios and HT’s.  You never know when you might need them.

VTAC Channel VHF UTAC Channel UHF
VTAC-1 National Simplex 146.520 MHz UTAC-1 National Simplex 446.000 MHz
VTAC-2 146.535 MHz UTAC-2 446.025 MHz
VTAC-3 146.550 MHz UTAC-3 446.050 MHz
VTAC-4 146.565 MHz UTAC-4 446.075 MHz
VTAC-5 146.580 MHz UTAC-5 446.100 MHz

Some folks just pick any old frequency for simplex but that really is not wise.  If you are not careful, you can accidentally pick a repeater frequency.  Also, you must remember that VHF simplex frequencies need to be at least 15kHz apart and UHF simplex frequencies need to be at least 25kHz apart (as shown above) to avoid interfering with each other.  We began with the VHF National Calling Frequency as the baseline at 146.520, then for each succeeding “channel”, we went up 15kHz.  We also began with the UHF National Calling Frequency as the baseline at 446.000, then for each succeeding “channel”, we went up 25kHz.  At this point, this is merely a proposed plan–just a suggestion.  Let’s hear your thoughts.
