Dear List, This is in no way a flame on anything, but I would like to know which Ten-Tec rigs are prone to a "dirty" RF shack. I've heard the Jupiter is prone to having problems in a shack with stray
Hey Roy, Anticipating RFI, knowing what it is and understanding what to do about it is far different from what the folks who complain about it on the internet ham forums such as this. If you begin wi
Roy, One of the best and easiest ways to avoid "RF in your shack" is to make sure that one half the length of your antenna plus the total length of your feed line is NOT an odd quarter wavelength lon
The use of aluminum instead of ferrous material (steel) for chassis, separate compartments, etc. is probably one of the greatest reasons TT rigs are more RFI prone. Dan -- N3ND Send TenTec mailing li
Interesting. What about using copper for shielding? It's not ferrous but seems effective. Perhaps you could elaborate. Steve Ellington N4LQ@insightbb.com -- Original Message -- From: <n3nd@aol.com> T
I am curious about "FCC type requirements". I know that transceivers use in commercial and CB radio service need to be "FCC Type Accepted" for their particular use. Type acceptance means that the eq

Roy: Any rig is subject to RFI under certain conditions. Some are more prone than others while some fair better in random RF fields. The general conditions which contribute to RFI issues are those ri
I believe what you just said was this: "Roy, One of the best and easiest ways to avoid "RF in your shack" is to make sure that one half the length of your antenna plus the total length of your feed l
Bob, I respectfully disagree with your statement above. It seems to be waaay too much of a generalization. I have had several 100 watt radios in the same physical location with the same antenna (i.e.
Bob: I agree. The radio is usually at fault. After all, radios do produce the RF and it should be able to survive in it's own RF field. This goes to peripherals such as keyers too. I've had some earl
Cannot speak as to the Orion, but I have 5 Ten Tec xcvrs 3 KW amplifiers two home brew and three MF495 Keyers. I have no RFI problems with any of the above Do not bother the computer sitting alongsid

One other very important point is to make sure that your station is not 1/4 wave, electrically, above ground. Many times in today's world the antennas that we use are not required to have any type of
Aluminium provides more than adequate shielding against both magnetic and electric fields at shortwave frequencies. But plastics do not, and Orion's CPU, DSP's, AD and DA converters, front panel LEDs
One "easy" way to reduce the "RFI in your shack" is the old time counterpoise. Just a quarter wave length of wire for each band, connected at the ground post of your transceiver and then strung out a
I'm certainly not disagreeing with Gary...BUT What is THE most important part of your ham radio system? In my opinion, it's your antenna. Why not build your antenna carefully and correctly to begin w
And I'm not commenting on any issue but the counterpoise to move the RF high voltage point off the equipment in the shack. I have addressed audio, lightning, RF, and protective AC grounding on a prof
MFJ makes a counterpoise tuner. I use it while in Florida in the winter from a 3rd story condo. I had TVI & telephone problems until I got one. Works great with 30 ft. wire around baseboard. No more

Absolutely RIGHT Bob, That hams need to understand the difference in why you use a ground rod and the other grounds in radio. (Rod-Electrical safety only, static discharge ground for arrestors). And
