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).
