Jan (ZS1VDV) and Rassie (ZS1YT) went to Hanskop to investigate the controller not responding to DTMF.
Started packing vehicle 06:30, left Stellenbosch 07:00.
Had to drive very slowly up as the road is in very bad condition and had the sun just over the horizon.
On site by 08:15. The temperature outside was 1.2 degrees, the wind was cutting through everything.
The problem with the controller was found to be interference on the 145.600 Repeater. The interference is not from our equipment but most likely from WISP equipment.
The 145.600 repeater’s SQL was closed to 1.1uV (about 4 times more that what it should be). This only helps about 80% of the time. The interference will need more work/investigation.
All SWR was checked. VHF repeater (1.1), UHF repeater (1.1), Jonaskop link (1.6).
CTCSS was added to the 434.650 repeater.
Home at Stellenbosch by 12:45.
