Another thing you could try is to throw some ferrites on the microphone
cord...............the kind that are placed on power cords to prevent RF from getting into equipment. This might work if the RF is being picked up by your mic cord. If you have an RF problem because of inadequate decoupling causing RF on the shield of your feedline, that is another problem. Pete "Steve" wrote in message ... I don't think you said what kind of antenna you are using. If using a magnet mount antenna why don't you just extend the coax length by 10 or 15 feet with RG-58X coax and put the antenna on some sort of metal sheet, tin cookie sheet or a metal filing cabinet or something like that. At that distance the antenna should be far enough away to stop the problem. Also, this shelter you spoke of, I can't see the walls being a problem for RF getting out although high power would is best for longer distance.

Now, Since I plan to use this rig close to the antenna, how do I keep the rf out the rig? I guess I will have to put in a steel tool box and keep the head outside of the rig. Any other Ideas.

Does anybody know why this might be happening. Thanks Chip |

How well does it behave at its lowest power setting in your preferred layout? Can you reliably hit the repeater at that power? Have you tried clipping ferrite beads to the power leads, any external speaker leads, any control head/main body leads, and the mike cable? -- To design the perfect anti-Unix, write an operating system that thinks it knows what you're doing better than you do.

Does anybody know why this might be happening. Sounds like you might have a little RF getting back into the keying circuit, possibly as a result of an antenna failure of some type. Can you duplicate the problem transmitting into a dummy load? -- To design the perfect anti-Unix, write an operating system that thinks it knows what you're doing better than you do.

Does anybody know why this might be happening. Another possibility that just occurred to me is the existence of a "one touch" PTT arrangement, where the mike needs two discrete presses of the PTT to switch into transmit then back out. What happens if you release the PTT then depress and release it again? -- To design the perfect anti-Unix, write an operating system that thinks it knows what you're doing better than you do.

Well it as definately RF getting into the rig. I put the antenna on top
of my car and the rig worked perfectly. Now, Since I plan to use this rig close to the antenna, how do I keep the rf out the rig? I guess I will have to put in a steel tool box and keep the head outside of the rig. Any other Ideas. Chip Ralph Blach wrote: I have a Yeasu ft8100r dual band 2m /440 rig.
