Hi, folks!
Last report for the month, and a fair amount of activity of late. Check it out! 🙂

Hawequa maintenance 20170128
Paul ZS1V went to the Hawequa 145.650 repeater site on Saturday morning 28 January, to diagnose a fault that was causing the link to operate in one direction only.
The effects of the recent fire were evident.  The veld had burned on both sides of the access road and to within 1m of our building that houses the repeater.  Fortunately, both our building, tower and the area in between where the coaxial cables are in the cable tray, were spared.
The destruction was quite wide-spread. Â The poles supporting the electrical feed to the site have been burned and will likely need to be replaced. Â For now, the power is still on.
Some diagnostics on the link controller were done and some settings adjusted.  The link is functioning correctly again, albeit still with slightly misaligned audio.  This will remain the case until firmware fix is provided by the link controller suppliers, enabling the return to the required configuration.

Hi everyone!
Yup, that time of the week again and, for your reading pleasure, a fresh status report! 🙂
Donations and maintenance/improvements top of the list. Enjoy!
Link Installation Hermanus 20170115
ZS1TAF left home at 07:00. ZS1DDK, ZS1VDV, ZS1V and ZS1OR were collected and all the equipment was loaded in 2 vehicles.
The team arrived on site at about 09:45.

Unpacking
The weather was windy, misty and there was some rain to complicate matters. The team all got stuck in and many of the tasks were executed in parallel.
Raining, ZS1TAF sealing new UHF antenna, ZS1V keeping rain off ZS1VDV tuning the duplexer
The first step was to confirm the correct SWR on the current VHF installation. Â This was found to be an acceptable 1.2:1.
The previous repeater was removed and the hut cleaned out. Â A Webb HD400 UHF dipole, fed by half inch Heliax and an LMR400 patch lead, was installed with lightning protection, for the link to Hanskop some 40km away.
ZS1TAF sealing the UHF antenna with ZS1OR
The duplexer was retuned which improved the insertion loss from 3 dB to 1.5 dB, and the rejection from 65 dB to 82 dB).
145.725 duplexer results after tuning by ZS1VDV
The UHF power output was measured at 2W and SWR on the antenna system after installation at 1.1:1.
As with many of the WCRWG repeater installations, the new link controller installation includes inside and outside temperature sensors as well as a DC voltmeter that can be queried by sending DTMF codes.
The repeater power output was measured at 10w after the duplexer. Â Due to local noise levels, the squelch of the repeater had to be tightened somewhat.
The team left the site at about 13:00 and everybody was back home with the vehicles unloaded by around 16:00.
Repeater Status Report 20170110
Greetings, interested readers!
It’s been a bit of a scorcher today, seems to me. I was thankful for a short-and-sweet cool shower this afternoon. Hopefully a bit of a breeze will spring up to cool the place down.
Got yer weekly report right here. Enjoy! 🙂
Repeater Status Report 20170103
Greetings to all and Happy New Year!!
I sincerely hope that everyone has a wonderful year ahead and that, accordingly, it is a vast improvement over last year. Shouldn’t be too hard.. 🙂
My inbox has been almost painfully quiet since the last report of 2016, except for a gentle hint that all was not well with said report. Oh, it was very much the correct report but the date on the top was accidentally left unaltered. I blame the puppy that was chewing my ear 🙂
A corrected version is available on the website and the faulty version has been removed. Please feel free to collect a copy if you wish.
This week’s report, the first of the new year, most definitely has the correct date – I’ve checked if 15 times – and is as up-to-date as the reports that I have received. Enjoy!
