Grounding to the AC receptacle "round" connector will normally suffice for AC mains and safety ground. As for RF ground, you may get away without it depending on your antenna situation. If you have "RF in the shack" problems, "counterpoise" wires may be the best solution. A quarter wave wire for each band you intend to operate will provide a low impedance (RF Ground) for that band. The wires can run around corners with gentle bends, but be aware that they should be insulated, especially at the ends because they can have high RF voltages even at QRP levels. Treat those wires the same as an antenna element with insulators at the ends and keep the wires away from possible contact by humans and pets. Insulated wire is OK.
An artificial ground will do the same as the "counterpoise" wires, but must be tuned for each band. Your physical situation will dictate which alternative you should choose. 73, Don W3FPR On 7/30/2011 9:43 PM, Radio Station wrote: > I'm looking at getting the KPA500, but need to find a way to ground my K3 as > well as the KPA500.
