17 January 2020

Lady's Slipper

ZS2AFB, ZS2DLF

Andrew visited the site to check on the status of the wall repairs.  He also removed the Icom IC718 for safekeeping (no longer usable via Ham Radio Deluxe) and the VHF 145.700 repeater for repairs.

Damien ZS2DLF had a quick look at the repeater and confirmed the TX is noisy.  Also found a blown 15A AC fuse - to be investigated

22 January

Lovemore Heights

ZS2AAW

Re-install the DSTAR VHF repeater on site.



From bottom up:  DSTAR Repeater, controller, DC-DC converter, Ethernet POE supply and switch

9 January

Mount Rd

ZS2AAW

Investigate the over-deviation from UHF link -> VHF Repeater.  Levels tested on the UHF link receiver, and through the conference network all OK.  Found TX line level high on Philips PRF10 VHF repeater.  As soon as the pot was touched, levels jumped back, so the pot was dirty.  Worked its case and reset to -10dBm = 1.75kHz dev.  TX power = 25W, all OK.

UHF Link appears to still only have 2ch EPROM - change this to 4ch version next time.

Backup batteries looking in good nick.  All green.

6 February 

Lady's Slipper

ZS2AAW

Remove conference network to investigate the door alarm spurious reporting.  Fitted a spare Philips PRF10 for 145.700.  It has some issues with the squelch tail not always being there...

Replaced the ventilation fan louvre and controller, due to burnt fan power connector

10 April

Mount Rd

ZS2AAW

Permanent key fault.  Found IRLP Computer to be the cause.  Removed for repair

10 April

Longmore

ZS2AAW, ZR2BK

UHF Link towards PE/Slipper TX faulty.  Found exciter module power rail missing - no Power LED.  Removed for repair.

One 12V 100Ah battery has a red indicator - low electrolyte level.  Bring water next time...


 Site in need of some maintenance (next time)

10 April

Ladys' Slipper

ZS2AAW, ZR2BK

Investigate the failed VHF repeater.  Found spare to be dead, removed for repair.  

Also checked the wifi link to Mount Rd - the POE power supply/injector seems faulty.  LED Comes up but no power injected.  Fitted the repaired Ethernet POE modified switch, and the port comes alive.  Still no link to Mount Rd, but will check from the other end, from home.

1 May

Longmore

ZS2AAW, ZS2MIC

Return the repaired UHF Link TX exciter module to site, re-installed and all working again.
Topped up the low battery with distilled water.  Indicator went silver = "recharge".

Do some weeding in the yard, looking much better :)
