On Sunday 5 June, the team consisting of Jan ZS1VDV, Paul ZS1V, Mike ZS1TAF, David ZS1DDK and Andre ZS1AN headed to Jonaskop to attend to a number of issues at the 145.675 repeater site.
It was a sunny, but cold day at around 1C when the team arrived, but warming to a comparatively pleasant 7C by the time we left at around 5pm. A light breeze aided in keeping everybody’s hands cold.

Jan ZS1VDV selecting the correct scalpel
The following tasks were completed:
- Replacement of a faulty speech chip in the controller and re-enable temperature and voltage measurement macros
- Correction of the audio emphasis for audio from the links to the 2m repeater
- Realignment of audio talk through levels
- Installation of a second backup battery
- Reinstallation of the VHF ferrite circulator and harmonic filter after the latter was retuned
- Improve station grounding
- Install vent covers on the equipment housing
- Investigate and correct interference problem on the 2m repeater – VHF SWR was high (> 2.5)

At the end of the day, a light crackle in the repeater tail was traced to the audio mixer in the controller. This was also corrected.
