NEXT MEETING – ONE WEEK LATE:  MONDAY JULY 10th
Location:  Larry’s Pizza, 12911 Cantrell in Little Rock
Program:  DRM Decision Day + Tim Leet, K5TEL on Cross Band Repeat

We are ready to move forward with the purchase of a new DMR repeater and get it on the air and linked into the world-wide Brandmeister System.  We talked about this at our last meeting on April 3rd and we conducted a paper survey.  The group (both members and non-members) gave overwhelming approval to be part of the DMR movement.  Everyone who filled out a survey, also committed to pledging some money to the cause.  So, bring your checkbook to the meeting!  Our project manager for the new DMR Repeater is Michael Clay, AC5XV and he will be there to answer any questions–including the location where the repeater will be installed.

After the DMR discussion, Tim Leet, K5TEL, will talk about the entire concept of cross band repeating…in other words, he will describe the proper way to use your mobile radio as a cross band repeater to help you boost the range of your handheld when you are near your mobile radio.  There are many who do not understand this simple amateur radio concept and often times, we end up with some very unfortunate interference on our system.  Cross band repeating is fun but you must set up your radio and the frequencies properly to avoid interfering with other repeaters linked into the AR Links System.

You can be sure that we will have a great program, so mark the date, Monday, July 10th, one week late due to Independence Day on Tuesday of the previous week.  We feel that a lot of folks will be taking a four day weekend, July 1st – 4th.

As usual we will raffle some tremendous door prizes including a new Baofeng GT-3WP dual band, hand held radio plus other prizes such as Craftsman tools and other items.

443000_machine

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

AR Links System Welcomes a New Partner, WD5B
146.685- (141.3) in Dardanelle

146685_smallThe 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! 

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.
