Repair Trip
N5HYD
  • LOCAL REPEATER:
    • White noise slowly increased for about a week until it overpowered all audio on Local Repeater transmitter. Brought system down to the shop. 
    • Transmitter was doing >50 watts. Used software to lower transmitter power setting from 255 to 123 to set output power to 25 watts. 
    • On the bench, the noise did not appear for the first few hours. Traced noise to the transmitter unit in the Vertex VXR-5000 Local Repeater. VCO voltage was low (I think). Adjusted to about 4.0 Vdc.
    • Added ADM modules to Local Repeater and Link Radio.
  • SYSTEM: Full alignment to 4.2 KHZ audio.
  • BATTERIES:
    • 12,8 Vdc at ~10:00 A.M. System had been toned off-line for a few days. Removed fuse on Charge Controller while I have the system off of the mountain.

W5ATO - KD5RJE - W5DWI
  • LINK RADIO
    • "Blowing raspberries". Receiver falsing and Controller COR LED flickering. There is something in this system putting a very low powered signal out on 448.000. Re-positioning the Link Radio helped but decided to go ahead and replace the Link Radio with Motorola serial #778TRQ1404.

07 December 2004
Upgrade NO TRIP!
W5ATO - N5HYD
  • LOCAL REPEATER

01 October 2003
Repair Trip
N5HYD
  • 440 LINK REPEATER:
    • Receive squelch falsing especially in the evenings. Replaced receiver SAS board.

17 September 2003
Repair Trip
N5HYD
  • 440 LINK REPEATER:
    • Transmit power still intermittent. Found an open solder connection on the input connection of the final amplifier transistor. Resoldered connection.
    • The transmitter in the  420 Link Radio that connects this site to the Sul Ross site causes the 440 Link Repeater receiver to "blip" on occasion. Tried various things including moving the 420 Link Radio antenna lower down on the tower to move it away from the 44 Link Repeater antenna but could not get the problem to go away. It is unknown as to why this has suddenly started occurring. It is not detrimental and that system is still working so stopped troubleshooting for now.  
  • POWER:
    • Replaced loaner Charge Controller with a new replacement Sunwize Technologies SIGMA controller. This controller has low voltage disconnect which was wired in to the repeater system.
    • Added the single old panel at the base of the tower through a small charge controller to the spare battery stack. 

14 September 2003
Repair Trip
W5ATO, N5HYD
  • 144 REPEATER:
    • Lowered repeater transmit power from 10 to 7 watts by using the Vertex software. The software setting for high power was reduced from 255 to 90. We also set the low power (high temperature foldback) from 90 to 30 or so on the lower power side.
  • 440 LINK REPEATER:
    • Lost transmit during the morning while Bill and I were at another site. Started working again just as soon as we removed the metal covering the repeaters. Something intermittent inside the link repeater as the link receiver would false whenever the repeater case was tapped. We finally noticed that the two repeater - duplexer coaxes seemed to be the most probable cause. Swapped the two coaxes (RX became TX and TX became RX)... We'll see.
  • POWER:
    • 12.09 Vdc at 3:00 PM completely cloudy.

07 September 2003
Repair Trip
N5HYD
  • 440 REPEATER:
    • Falsing on receive all last night. Not falsing on arrival on site. Increased squelch and re-arranged coax cables away from signal cables.
  • 420 LINK RADIO:
    • Increased squelch.
  • POWER:
    • 12.44 Vdc at 9:00 AM cloudy. Panels starting to charge.

KD5RLX (Joe), KD5VUC (William),
AD5OJ (Johnathon), Charles, W5ATO, N5HYD
  • POWER:
    • Added two more ARCO M73 solar panels. We now have 6 M73 and one old panel in circuit. Removed one of the 2 old solar panels that are damaged and not hooked up.
    • Replaced suspected failed Charge Controller ASC SCC-1/30-12 #Q3995342 and replaced with temporary spare Charge Controller ASC 12/16 #Q402441774.
    • Replaced the three batteries in circuit with 4 ST154 12V, Deep Cycle batteries purchased from Sams Wholesale - Odessa. Moved the 4 older batteries to storage on the floor of the building.
    • 7.5 amps charge current, 12.87 amps with all repeaters transmitting. 11:00 AM Sunny.

01 September 2003
Repair Trip
W5ATO - WT5O
(Way to go Bert!)
  • POWER:
    • Removed one battery from stack. W5ATO comments:
    • Numbering the batteries from back to front (1 being the far battery and 4 the near battery as you face the box,) the number 3 battery showed a voltage loss of more than twice that of the other batteries. With all batteries disconnected from each other and no load connected, I took a reading just after disconnecting them and a reading after about 25 minutes. Here are the battery numbers, first voltage, second voltage and voltage difference. ( I believe the voltage while everything was still connected was right at 12.00 volts.) 
      1. 11.92   11.85   .07
      2. 11.95   11.90   .05
      3. 11.26   10.97   .29
      4. 11.94   11.86   .08

      Based on this information I made the assumption that battery number 3 was probably drawing current away from the rest of the array and charging system and keeping the system from recharging as quickly as it should. So I removed number 3 from the system. Of course the weather cleared so we can't be certain this helped, but I think it is obvious that something is wrong with number 3 anyway so I don't think we hurt ourselves any.
      Bob (WA5ROE) seems to think, and I have to admit it makes sense, that if we replace batteries at a site, we should replace all of them at the same time (per site of course) and using all the same model battery.


30 August 2003
Repair Trip
W5ATO
  • POWER:
    • Insulation on wiring to far east side (old) solar panel rotted off. Hot side of wiring shorted to ground which shorted all panel current to the charge controller. Removed 2 of the three east (old) solar panels from the system. This leaves 2 old and 4 new solar panels wired in as well as the tower side (old) solar panel.
  • CHARGE CONTROLLER:
    • (Information only:) 11.27 VDC shut-off on Low Voltage Disconnect.
  • ETC:
    • 17 minutes climb time.

09 August 2003
Maintenance Trip
W5ATO, Kendall Craig 
  • CONTROLLER:
    • RX-2 (440 Link Repeater) J8 was off. I thought the MastrII picked audio off of VOL/SQ HI which means jumper J8 should be off to disable the De-Emphasis. Apparently this is not true. Added jumper to J8 and aligned pot RX-2 CCW about 2 tick marks to make up for loss in audio levels.

13 July 2003
Repair Trip
W5ATO, KD5MXR 
  • POWER:

  • POWER:
    • Replaced temporary controller with repaired original controller.
    • Removed temporary tape used to deactivate a solar panel to reactivate it (it was disabled because the temporary charge controller couldn't handle the extra current). Tape adhesive stuck to panel.
    • Checked two deep cycle batteries for water, all cells were full. Two BP gel cell batteries are sealed and there is nothing to check.
    • Radio equipment is connected to battery terminal of charge controller so there is no low voltage disconnect active at this time. There is one open, half-full, gallon of distilled water at site. There are 3 - 24 oz. bottles of sealed drinking water. 
  • 144 REPEATER:
    • Checked DTMF tone decode LED on controller panel. LED indicated DTMF tone on all keys
  • 420 LINK RADIO:
    • Checked aim of link radio antenna to Sul Ross. Can see Elephant Mountain from site.

13 November 2002
Repair Trip
KD5MXR
  • POWER:
    • Entire repeater system off the air. Charge Controller Low Voltage Disconnect (LVD) was on, which disconnects the load from the batteries. Charge LED was on. Batteries at 12.2 Vdc, which means the LVD should not have been on. Reset the LVD switch and system came back online.
    • Left the LVD switch in "NO LVD" so this won't happen again.

  • POWER:
    • The two strapping youths carried up 4 loaner UT solar panels while their dads carried up 2 new deep cycle batteries. Installed batteries.
    • Replaced 4 old solar panels with 4 loaner UT panels.
    • Smoked the Vertex repeater somewhere in the process. The Vertex repeater worked though, after replacing the 10 DC fuse in the ground wire lead.
    • Hooked in new solar panel system at 6:38 PM so the repeater spent the day without charge current.
    • 12.26 Vdc 11:21 AM, 718 mA unkeyed, 10.75 Adc all keyed. clouds and raining.
    • 12.64 Vdc 12.52 AM, 2.7A charge current cloudy. I think this is after the two new deep cycle batteries were installed.

    • 12.58 Vdc 6:38 PM, sunny. New panels just hooked up
    • 12.62 Vdc 7:16 PM, and dropping because the sun is down and the panels are shaded.
  • OTHER:
    • Some weird noises on the way down. Sounded like a small girl down by the pick-up screaming "Daaaaddddyyy" at the top of her lungs. No-on seen. Maybe a kid goat or the Twin Sisters ghost or something. I didn't stick around long enough to trace it down. (I was alone by then).

23 Aug 1998
Power Cycling
  • POWER:
    • Removed 1 cell from each bank. Now back to the correct 6 cells per bank. Paralleled the 2 cells from the spare set across the bottom cells of each bank (if you can picture that). Charged left bank until charge controller shut off. Charged entire system with repeater power off until I got tired of looking at it. The charge controller never cycled so powered up repeaters and left them control coded off until the batteries recharged.

Maintenance Trip
To Repair the 05 Aug Failures

  • 144 REPEATER:  Replaced Vertex MODJACK board and left the installed board electrically disconnected (not needed).
  • CONTROLLER:  Installed repaired RLC-4.  Had replaced U11 LMC660 and the UDN2597A at the shop.
  • 420 LINK:  White noise.  Pointing the 3 element beam towards Mount Ord fixed it!?  K5FD guessed that the wall of the metal building behind the beam was affecting it. Pointing toward Mount Ord also puts the wall of the building perpendicular to the antenna.  Whatever works, I guess.

05 Aug 1997
144 Repeater TX Locked On

  • 144 REPEATER:  Vertex MODJACK board, Q8202 shorted.  Removed MODJACK until a replacement optoisolator is ordered. Changed Vertex S2004 to "HI" (RX audio to RLC-4 controller increased).
  • CONTROLLER:  Replaced smoked RLC-4 with RLC-1.
  • ALL:  Full alignment.

14 May 1997
Low 144 Repeater Range

  • 144 REPEATER:  2 meter "Mobile Mark" antenna bent over 90 degrees at base.  Found an empty bottle of Tequila under the antenna.  Re-bent back to vertical.  TX also over deviating.  Adjusted R42 (TX3) down to lower the TX gain from the RLC-4 controller to the 146.720 Vertex Repeater.
