....the new YORK Affinity Heat Pump system installed at my home causes severe RFI on a couple of the ham bands...10db over S9 on 20M and 17M...and moderate RFI on almost all of the HF bands.  The noise is coming from the OUTSIDE unit and only occurs when the fan is running.  Has anyone else had this problem?  Any suggestions for a cure?   Many noise spikes are seen on the waterfall.  Thanks.  73
