[Solved] WiModem on C64 Reloaded : Interference?

[scanword]

Anyone else getting slight screen "interference" issues on a C64 Reloaded? (Text on the screen is wiggling at random when wimodem is connected).
I don't notice any "interference" issues on a normal breadbox C64.
I tried shielding the C64 reloaded but that didn't seem to do anything.

Update : Swapping the replacement 8701 with a real one solved the issue.

Hi listen I have the same problem I have a reloaded mk2 and I use a power supply 12 volts 5 A (not its original), practically connecting the wimodem flickers a bit to the edges as if a current would pass by now and then how can I solve this? ?? I did not understand what is the 8701 ???
