Visit to MK check on power, good. noticed rouge signal coming in on DMR repeater slot 1 at exactly 20 second intervals with no visable user showing up on dashbaord, traced to another DMR repeater in the area. Changed Color Code to 4 from 1 signal gone. Sent email to club members of change as well as club president. Dashboard updated to show CC 4
Maunakapu UHF Analog repeater replaced with Motorola SLR5700 DMR repeater on the brandmeister network using same frequency pair coordinated with Rick Ching. Tuned tested, rpt output 35 watts. Battery power holding good at 12.9 V with 13.6 V @ 4.4 amps in from the solar panels. Conditions at the time about 11:00 am were cloudy.


Added 40 foot Tower to Mauna Kapu Site and affixed VHF antenna to it with new coax. UHF antenna relocated to top of 20 original tower at site with new coax. Tested good at 1.2 swr each. Both antennas are dual band however tuned to their respective frequencies.
MK-146.80/444.100 Replaced Battery bank at MK this afternoon with 10 Eaton AGM 500 watt batteries. Power 13.1 V at estimated 416 amps. Load was 12.6 V @ 1.2 amp idle 8.6 tx/Float was 13.4 V/Panels were showing 14.1 V @ 7.7 amp Charge rate. Reduced Power to 25 watts on each repeater.


MK-146.80/444.100 Internet connection resolved, Adjusted input/output audio/ per 50 watts, swr 1.3. Batteries 13.3 volts.
Laie, 146.640 repeater off the air after someone (Sprint contractors) Stole our antenna, cut and stole our Heliax, broke into the room where the repeater is by removing the pins for the door, thus cutting the coax and turning off the repeater. We are treating this as a theft and have an approximate date of the occurrence as May 9, 2016.
146.880 DH repeater worked on today. Receiver at 2.0 mv input, no de sense noted, tx power lowered to 58 watts. Output PL removed due to audio issue when transmitting the PL tone. PL 88.5 required to access repeater. System is up and Stable at this time.
146.660 Olomana Repeater added to the linking system via Allstar and IP. PL changed from 103.5 to 88.5 TX/RX, however will accept input PL of 103.5 to allow time for folks to change their radios, will only transmit output PL of 88.5, output power 17.5 watts out the duplexer, .02 watts reflected. 449.150 Olomana UHF repeater taken out of service, output power 0.15 watts, will need to be sent in for repair. Once repair UHF will be returned to service and frequency reversed to match current band plan to 444.150 TX 449.150 RX with PL of 88.5.
146.880 Diamond Head Repeater added into the DEM allstar network. PL added 88.5 input no tx pl at this time. Due to City Intranet unable to link out the 88 machine into the EARC links, will need to discuss possibility at a later date. We will also have to redo the node numbers, as communication was not clear on which private node numbers are in use. Will be done later this week.
Maunkapu repeaters (146.80/444.100): Added input/output PL 88.5. Rechecked Audio and Deviation. Upgraded computer image with new RPI software eliminating audio delay. Tested good 50 watts.
146.880 Repeater moved to new PSB building on Diamond. Tested good at 100 watts. Repeater tx antenna awaiting permanent installation, currently tx antenna is located at a lower spot on the front of the building which will affect coverage until permanent new pole can be put in
The Kenwood TKR repeaters were replaced with new Icom FR-5000/6000 repeaters. Internet was added with the Cradlepoint IBR600 router and Verizon service. Installed RPi2 Computer with new DMK URI's. Added Icom IC-6011 LMR for RF Link to Diamond Head and installed Yagi Antenna for the link. Repeaters tuned to 3.5 khz deviation and set for maximum output with a 1.5:1 swr. Added D4 260 amp battery to the system (donated).
Maunakapu site upgrade and repair. A crew of members went to the site, repair was done on the existing tower and better securement put in. tower was raised 15 feet, V and U antennas were given better separation. A ground rod was put in place and connected. Two more solar panels were added for an additional 500 watts of power and a new 60 amp solar controller was added to prevent further power glitching.
Current Kenwood TKR-750/850 to be replaced with newer Icom FR-5000/6000 interfaced with Allstar and IP linking. The Kenwood UHF was removed from service and the VHF was left online in stand alone mode, the controller was disconnected. Currently the VHF is not ID'ing and needs to be manually ID'd.


No significant changes

Maunakapu repeaters placed back online and working ok.

146.66 MHz repeater is back up. The board is green. Todd conferred with Jim and reset the alarms.
146.66 repeater is down due to a continuous CW ID.
All repeaters are still up. No major problems reported since June.
All repeaters are up. Jim, KH6JKG writes, "Today I managed to get to Mauna Kapu in the PM. I installed one of the VHF Eng. that was tuned up for 146.20/146.80. The Motorola mobile didn't operate porperly. So, I will need to do more troubleshooting on this unit, time permitting."
146.88 MHz repeater is back up. Jim, KH6JKG and Randy, AH6Q picked up the VHF repeater from the HFD radio shop and reinstalled it at Diamond Head.
From Todd, KH7UK, "The 146.880 repeater is down due to very weak output signal. It sounds as if the power amplifier may have failed. Reports from Mike WH7T and Ray NH6RZ state that the repeater dropped out about 2100 Monday night. It was stated that this occurred about the time of the Makiki area power failure last night. Coincidence? Hard to say. Mike also brought up the possibility that rain got into the feedline, causing an increased SWR, causing the PA to shutdown. Whatever the case, I disabled the VHF side transmitter in case the PA is still trying to run full power into high SWR. When I tested it, transmit power was very low, similar to the Y2K failure when the PA of that machine failed and the exciter transmitted barely to the Makiki area. The UHF repeater 444.500+ is up and operating normally to the best of my knowledge. I may enable VHF receive only, so in case someone calls on VHF, at least people listening to UHF can hear them."
AH6QO DE KH6JKG: Please change D449.150- to: U449.15- (in green.) Todd, did a great job on balancing the audio. ID's, UHF, VHF. Plus adding more labels. So, If there is ever a need to change or upgrade the controller, the process is less time consuming.
