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

We arrived on site around 08:15.

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.  The duplexer, harness is also suspect and have been returned for servicing.  The antenna and coax was all working fine.

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

Returned home around 12:00

It was an early start 05:45 in Stellenbosch.  06:10 Somerset Wes. 06:30 Strand.

ZS1VDV, ZS1V and ZS1YT were on site at 07:30.

Moved temporary brackets further apart to stabilize new 6m galvanized pole.
Stays were added.
Mast groundwire added.
Antennas moved further apart.
All seals were redone in dry weather.
Cable tray was reinstalled.
VHF repeater SWR 1.1, UHF repeater SWR 1.2 and Jonaskop Link Radio SWR 1.7.
New power supply installed (Donated by ZS1K).
UHF repeater and Jonaskop Link Radio is connected to new power supply.
VHF repeater connected to Nova power supply.

Collapsed tower visible on the left. WCRWG temporary installation visible on the far side of the building with Jonaskop link beam at the top.

Default linking moved to all linked.
DTMF updated to measure 2 power supplies.

Home 15:00

Jan(ZS1VDV) started to pack all the equipment at 05:15 in Stellenbosch.

Picked up some Heliax and antennas at (Paul) ZS1V 06:10 in Somerset West. From there it was a quick hop over to get (Rassie) ZS1YT.

On our way up to the high site, we noticed that we could not see our tower, but did not think much about it, as it could be the angles from the back or maybe weather.

Tower on the ground

When we got on site (07:50), it was very clear that every plan of what was going to happen was 100% out the door. The first action was to recover all our current Heliax and antennas. We lost a RG214 connector (ripped from the cable), the recovered Heliax still needs to be tested but some real bad bends and marks are visible.

Next was to assess if we could do a temporary hack antenna installation with everything on site, which was not possible. With the help of ZS1V the plan was worked out. Andre(ZS1AN) and Kobus(ZS1K) did a few supply store stops and got a pole, more heliax and other sundries from ZS1V to bring to the high site.

ZS1VDV working on linking cables

While we where waiting for the supplies, ZS1VDV did a few changes to the controller link cables and audio alignment. A new 20A solid state power supply was installed. The next step was to clean and prep the area for antenna installation.

ZS1YT prepping Heliax

ZS1VDV drove down to the gate to open for ZS1AN and ZS1K. They arrived on site around 13:00. As soon as they arrived the weather started to turn for the worse. ZS1AN and ZS1K installed the 2 mounting brackets and ZS1VDV and ZS1YT prepped the new Heliax to be installed. Then ZS1VDV had to install the antennas on the mast in some very big wind and wet weather. A new FDC145 was installed for the VHF antenna, the dipole was reused for the UHF repeater and another UHF yagi was installed and pointed towards Jonaskop. The SWR was measured. The VHF SWR was 1.7 which was a bit high, but in the weather and time frame could not be corrected. The UHF repeater and link SWRs were 1.5 and 1.4. At this point it was also identified that there is a power problem on site as every now and then when touching a coax, a shock was felt. This was not ignored, just not enough time to resolve it at get everything running again.

Sealing cables

In a very small weather opening, the connectors was sealed. The last steps was to cable tie all the new Heliax and clean up the site.

Antennas after install

We left the site around 16:30.

At Strand ZS1AN and ZS1K left for home. ZS1VDV dropped off ZS1YT at home and the recovered Heliax and antennas at ZS1V.

Got home around 18:45 and the vehicle was off loaded by 19:15.

It was one of those days where you leave home in the dark and get home in the dark.

There is a list of todo items for the site. A future maintenance trip will be required.

For the first time ever in the Western Cape Repeater Working Group history. A contact was made between the Piketberg and George repeaters. The path for this contact, Piketberg -> Haweqau -> Bellville -> Hanskop -> Jonaskop -> Riverdal -> Danabaai -> George (8 hops, 15 radios and repeaters)

On Sunday 2016-03-13, ZS1V and ZS1TAF went to Hanskop to further troubleshoot the Jonaskop link problem. It was 5 degrees, windy and raining, limitting the amount of work that could be done outdoors. Nonetheless, several tests were done with a handheld 70cm beam and a handheld radio. Some re-orientation of the Jonaskop link antenna was also tried.

The functioning of the link controller itself was also verified as correct.

The Jonaskop link radio was removed for bench testing. The SWR of the link antenna was found to be unnacceptably high at the link transmit frequency and will be replaced on a subsequent trip.

ZS1DDK and ZS1AN started at around 05:00 from Bellville.

Picked up ZS1VDV at around 06:00 in Stellenbosch.

Got they key from ZS1YT at 06:30.

Arrived on site 08:30. Did a bit of 4×4 in the mist.

• Checked the SWR of the VHF repeater(1.7)
• Dismantled the full rack.
• Built in a UPS.
• Installed duplexer and bandpass filter (had to tune the band pass filter).
• Installed VHF, UHF repeaters and link radio.
• Installed a 50A power supply.
• Installed UHF duplexer.
• Installed link controller.

We struggled with local interference on site on the UHF and VHF repeaters. The VHF repeater squelch was closed to 0.37uV. (works now for about 99% of the problem). For the UHF repeater we had to switch on CTCSS.

The UHF link to Jonaskop is not operational, but the problem is suspected to be a misalignment on Jonaskop side (did recheck the alignment of the yagi on Hanskop side).

Had a quick bite to eat in Grabouw.

Back in Stellenbosch at around 17:00.

Back home in Bellville around 17:45.
