Repeater Status Report 20161018

Hi, folks!

First off, thanks to Jan for pointing out that I have fat fingers and that typing 156.650 when aiming for 145.650 doesn’t quite make the grade. πŸ™‚

Secondly, and I only noticed this right now, I forgot to change the date on the top of the first page of the report from the 4th to the 11th! Nobody pointed that out – did anybody notice? πŸ™‚

Lastly, I’ve been through this one with both pairs of spectacles on and it looks like I haven’t messed anything up… so enjoy! πŸ™‚


Maintenance Hawequa 20161009

ZS1YT, ZS1VDV and ZR1SWB went to Hawequa to investigate some errors after big Eskom/power outages/instability the last few weeks.

Wellington view


The morning started at around 07:00 with packing all tools and equipment. Left Stellenbosch around 08:00. On site at around 08:45.

First checked all voltage levels. It was found that the Benton Charger again was off and not charging the battery. The charger was replaced by an 10A Victron Energy charger which was donated by ZS1FX.

The link controller opened, and no damage could be seen. The audio paths was traced and all seemed in order. A complete firmware reload and configuration reprogram was done. At a stage last week the controller was rebooted numerous times(by power outages/spikes) and this caused the configuration to go faulty.

Left for home around 10:15.

Home and unpacked by 11:30.

Maintenance Hanskop 20160918


Reinstall 434.600 Repeater and Duplexer
Research interference from 145.600 Repeater on commercial repeater
Research interference on 433.000
Research 145.600 dropout on input from Jonaskop.

Jan(ZS1VDV) left Stellenbosch 07:30.

Reinstalled 434.600 Repeater and Duplexer. Checked SWR (1.1).
Interference on 433 was determined to not be within the hut.

The interference from 145.600 and the commercial repeater was determined to be proximity. Moving antennas will be investigated. (Before tower fall it was 11m vertical, now only 1m vertical and 3m horizontal)

Could not replicate the dropout. Problem will continue.

Back in Stellenbosch 12:40

Maintenance Hanskop 20160904

Jan (ZS1VDV), David (ZS1DDK) and Andre (ZS1AN) started early at around 06:00.

We arrived on site around 08:15.

View from Hankop

SWR was tested on a few areas on the UHF repeater, duplexer and antenna.

It was found that the repeater has a permanent PA error and will need to be serviced.Β  The duplexer, harness is also suspect and have been returned for servicing.Β  The antenna and coax was all working fine.

The VHF main power supply was moved from UPS power to mains power.Β  This will now enable an short over beep on the VHF repeater when power is out on site.

Returned home around 12:00
