If you don't mind wasting money on costly ferrite snap on cores at around $3 each you can mindlessly put them on everything, but at that cost they are a last resort for me. I try before that point: 1. inexpensive audio isolation transformers 2. small .01 ceramic bypass caps 3. 1:1 power isolation transformers 4. ungrounding cabinets, or grounding cable shields at only one end. 5. using balanced shielded audio cables You can try some of all of these depending on the specific station circumstances. These tricks don't work for everything but can in the proper application if the problem is keeping RF where you want it. The power isolation transformer is probably the most expensive fix but besides isolating direct rectifying power supplies off of the AC service line, they eliminate square wave line radiation, tunable hum, and station RF getting into the appliance. 73 Rob K5UJ _________________ Topband Reflector Archives - http://www.contesting.com/_topband
