I'm also having the same tick tick tick sound. Started after software update earlier this year on the WiModem. I hear it on my monitor, and also on speaker of the Ultimate2+ cartridge. Have tried on the C64c and a breadbin C64. Have tried different power supplies. With and without cartridge or any other peripherals. Even different locations in house on different monitors. Goes away when I unplug WiModem. Has anybody found a solution?
