I have a Ds1000 installed at my home/business. The system is great except that RFI from the system is wiping out my ham radio receiver. Ive done some investigating and found that the interference does not come from the ksu but from the digital keysets. Doesnt seem to be related to wiring only in how close my radio is to a keyset. The interference seems to peak around 21Mhz. Below this, isnt too bad. I know this is a long-shot but anyone ever experience this kind of interference? I have experimented with grounds at both phone system and receiver with no difference. One note: I am using open-wire feedline which no doubt adds to this problem. I would prefer not to switch to coax. Thanks!
