Monday Night, April 3rd, 2017 – 5:30 p.m.
Guest Speaker: Bob Hambuchen, N5OMW, from Conway
“Implementing DMR in the Faulkner County Amateur Radio Club” (FCARC)
Special Location: Jim’s Razorback Pizza at the Morgan Exit
Our next meeting will be on Monday night, April 3rd and we’re going to experiment with a different meeting place, Jim’s Razorback Pizza, just off the Morgan-Maumelle Exit on I-40 west.
Our guest speaker will be Bob Hambuchen, N5OMW, from the Faulkner County Amateur Radio Club (FCARC). He has an exceptional presentation on DMR (digital mobile radio). He will show us how the FCARC installed and implemented their DMR repeater on 443.750 MHz. Bob’s DMR presentation has been seen by many of our members and friends and we’ve heard some very good things! There is no question that digital modes are the future of amateur radio but at this point in time, it can be confusing to all but the most dedicated hams who have invested years in studying and developing the various species of digital modes. Don’t miss this meeting because we all need to learn as much as we can about digital.
We begin with pizza at 5:30 p.m. to 6:30 p.m. Then, affter a few announcements, we move on to the program at about 6:45 p.m. We will be in the banquet room at Razorback Pizza, known as the “BEAR DEN” to your LEFT as you enter the front door. Razorback Pizza does not offer a pizza buffet, so everyone should simply order any pizza of their choosing: their pizza’s are affordable and incredibly delicious! They also have salads, hot sandwiches and pasta dishes.
After the presentation, we will hold a raffle for some tremendous door prizes including a new Baofeng GT-3WP dual band, hand held radio plus some other nice prices such as Craftsman tools.

Please Pay Your 2017 Dues Promptly
Like most other amateur radio clubs, all memberships expire on the last day of the calendar year, regardless of when you last paid your dues.
One of the most important ways you can support the CAUHF Group is by paying your dues promptly at the beginning of each year. We have two classes of membership: an individual membership is $20.00 per year and a family membership is $30.00 per year which covers you along with your spouse or kids if they happen to also be a ham. You can pay your dues online (via PayPal) by clicking the tab above labeled JOIN OR RENEW, or you can mail your check to:
The Central Arkansas UHF Group
11524 N. Rodney Parham Road
Little Rock, AR 72212
Your club needs your dues to help maintain our impressive statewide repeater system and meet the other minimal expenses of the club. Repairing an antenna, feedline, repeater controller–or hiring a professional tower climber can cost hundreds of dollars. In addition to your $20.00 annual membership dues, we also accept additional donations of any size, at any time during the year. Every little bit helps!
For 2017, we are extending free memberships to any new ham who passed their exam in 2016. If your license was issued in 2016, please complete a membership application and send it in with no money–just mark it “New Ham, Licensed in 2016”. You will be full member for the entire 2017 calendar year.
“Ask not what your club can do for you–but instead, ask what you can do for your club”.

President of The Central Arkansas UHF Group

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.
This 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
AR Links System Welcomes a New Partner, WD5B
146.685- (141.3) in Dardanelle
The Central Arkansas UHF Group and the AR Links System would like to welcome Richard Duncan, WD5B as a new linking partner. Richard’s 146.685 (141.3) VHF repeater overlooks Lake Dardanelle and is linked 24/7 to the AR Links System through our main repeater 443.200 in Little Rock. This repeater gives us great coverage in the Russellville and Dardanelle area AND it’s on a backup generator! We have long wished for a repeater in this area. We are very fortunate to have Richard come forward and offer to link to us! Make sure this frequency is in your radio and give a shout anytime you travel I-40 through Russellville and Dardanelle With a good mobile, you should hear this repeater from Pottsville to Ozark and beyond.
Let’s All Get Together!
For 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”. These standard frequencies are taken from a similar plan developed by the New York City Amateur Radio Emergency Communications Service (ARECS). They use far more than 10 frequencies and they also use PL tones, but these 10 should be enough for us, at least for now. 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. From the ARECS plan, we used the VHF National Calling Frequency as the baseline at 146.520, then for each succeeding “channel”, we went up 15kHz. We also used 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.
