Three weeks ago, the 146.92 repeater abruptly failed. Guy, KC5GOI and Don, KG6LE made a site visit and determined that a 12 volt power connector had overheated and failed. They made temporary repairs and got it back on the air. At this time it was determined that the backup repeater located at the City of Denton’s site would not respond to commands to turn it on. A later site visit to power cycle the repeater fixed that problem.
A week later, after switching over to the City backup repeater, the primary 92 repeater was brought down to WB5NZV’s shop for permanent repairs and upgrades. The 12 volt power distribution was redesigned to split up the loads more evenly. In addition, bypass coaxial relays were installed to allow bypass of the final power amplifier.
Under normal power, the final RF amplifier is on line and producing 100 watts output. If commercial power fails, the systems reverts to battery power, the amplifier drops out and is bypassed by the relays. This now allows the repeater’s 20 watt transmitter to be connected directly to the antenna. This will greatly reduce the load on the backup batteries. Calculations show that the repeater can run for over four days on the batteries if the repeater use is kept to a minimum.
Other changes were updates to the programming. A new sensor was installed to monitor temperature inside the repeater cabinet. Cooling fans were cleaned and some replaced. Voter receiver radios were tested and repaired. And additional equipment grounding was installed.
Changes were made to the commands for placing the repeater in Skywarn, Event, and other modes of operation. Most notable is the switch from normal to Skywarn mode and back to normal mode. The command macros run a little longer, with “please standby”, “please wait”, messages while the changes are being made. It is requested that all repeater traffic stand by until the message that says the mode is up or has returned to normal.
The repeater was reinstalled at TWU Guinn Hall and placed back on the air Wednesday, January 22 by Don-KG6LE, John-KC0L, Doug-KE5WTL, and Gerald-WB5NZV.

July 17, 2013
The Justin remote voter receiver on 146.920 was placed back in service July 17th. It was moved from the Justin fire station radio tower to a water tower on the northwest side of the city. This location is 75 ft. higher than the previous location and should help mobile and portable operations from the Justin area. In the next few days, an APRS weather station will be installed at this site that will show wind direction, speed, and temperature.
At this time, remote voter receivers at Celina, Slidell, and Grapevine are in service. The Frisco and Little Elm sites are off line at this time but should be back on line soon.
February 7, 2013
The W5NGU-4 weather station on the 1500 ft. Rosston tower is online. Access the data at: http://www.findu.com/cgi-bin/wxpage.cgi?call=W5ngu-4&last=12
December 19, 2012
The KE5YAP D*Star repeaters have no Internet access at this time. Local RF only is available.
The W5NGU-4 APRS Digipeater is in for testing at a temporary site. This will probably continue for a couple of weeks.

Gerald and Mike have forcibly evicted the gremlins from the 444.050 repeater and all is well once again.
November 23, 2012
The primary 146.92 repeater is back on the air. The three voter sites in Celina, Slidell aand Grapevine are in service.
The 444.050 repeater has an interference problem that is being investigated. It may be turned off at times. This will affect Echolink users.
November 13, 2012

Gerald (WB5NZV) and Don (KG6LE) have repaired the 145.490 WD5U repeater on the Rosston tower today. The power supply had failed on it last week.
September 27, 2012
The primary 146.920 repeater was taken off the air Wednesday evening in preparation for installation of the new voter system and other upgrades. The backup repeater is turned on. It does not have a courtesy tone and does not have remote voter receivers therefore it will sound different and the coverage will be reduced for some, but it does have reasonably good coverage of the county.
It is uncertain how long this upgrade will take. Meanwhile, don't forget the other DCARA repeaters on 145.170 (110.9), 444.050 (110.9), and 443.525 (118.8) as alternative channels.
September 19, 2012
The W5NGU Echolink server has suffered a hard drive failure and is currently off line. A replacement computer is being built by Guy, KC5GOI, and should be back on line in a week or so. In the meantime, some of the nearby Echolink nodes are KD5OEW-R in Coppell, WA5CKF-R in Irving, KM5HT-R in Hurst, and K5AAM-R in Ft Worth to name a few. The host repeater here in Denton, 444.050-W5NGU, is still fully operational. The W5NGU Echolink node computer is co-located at my home station and is linked to the repeater via a UHF link.

The D*STAR repeater KE5YAP is on the air. It is located at the Rosston site. Both the C (VHF) and B (UHF) ports are operational. It is not connected to the internet yet. So you will not be able to use the reflectors or see your status online. The internet connection is a separate project that will be performed at a later date.
KE5YAP frequency info:
KE5YAP AD 1259.200 simplex data (Not online until internet connection)
KE5YAP AV 1293.200 - 20khz down voice
KE5YAP B 440.7125 + 5mhz up

July 9, 2011
The main DCARA repeater on 146.92 is fully operational at its usual location on Guinn Hall. It will be operating at reduced power for the time being.
All DCARA repeaters will be upgraded with new equipment in the near future. 146.92 will be the first to be upgraded. Specific equipment and time frame have not been finalized at this time.
D*Star: The Rosston equipment has been installed. The plan is to put it on the air next week. It will be UHF & SHF at that time. VHF will not be placed on air due to frequency coordination issues. It will not have internet connection until that specific equipment can be installed.
Denton/W5NGU D*Star VHF is being turned off for now due to coordination issues as well.
May 30, 2011
Sunday, May 29th, a trip was made to the 146.92 repeater site on TWU Guinn Hall by Mike/AE5IV, Guy/KC5GOI, Jerry/K5JLG, and Gerald/WB5NZV. It was discovered that the final transmit amplifier had failed. It was removed and taken to Mike's shop for repair or replacement. All other systems, power supply, batteries, control equipment, antennas were in good working order. We will continue to operate on the backup 146.92 repeater until the amplifier can be repaired or replaced.
May 26, 2011
The Rosston 147.020 went off the air Tuesday May 24th during the storms. Don Roberson/KG6LE, Dwayne Rohmer/KE5EFY and Gerald Marchant/WB5NZV went up to the site Thursday the 26th and found what was left of the antenna on the ground about 200 yards out from the tower after its 1500 ft free fall. High winds broke it off just above the mounting bracket.
The repeater was placed back on the air with a temporary antenna.
May 17, 2011
The main 146.920 repeater is experiencing power issues and is now offline and the backup is operational. The backup does not utilize the voter system, but you should still experience good coverage.
This is a good time to try out some of our other repeaters in the Denton area.
March 14, 2011
The 145.490 WD5U repeater located at 1500 ft on the Rosston Tower is now on the air in test mode with new equipment on 147.020 +.600 110.9 pl
The new DCARA D*Star repeater is now on the air at a temporary location in north Denton for beta testing. It is connected to a 30 ft antenna, therefore coverage is limited. The repeater call is KE5YAP and is running a full ICOM D*Star stack of VHF, UHF, 1.2 voice, and 1.2 data modules with internet connection. This new system will be installed on the Rosston tower at 1500 ft in the near future.
The W5NGU D*Star repeater located at the Denton County EOC continues to perform well. EchoLink is on line on the 444.050 repeater. The 146.920 is working well and now has a NWS alert receiver that will automatically broadcast weather alerts over the repeater. The 443.525 repeater is on line and has excellent Denton County coverage. Some noise issues have been reported on the 145.170 repeater and this is under investigation.
February 18, 2011, The 145.490 WD5U repeater located on the Rosston Tower has now been repaired and is back on the air on its new coordinated frequency of 147.020 +.600 110.9pl.
