I keyed the Base up. All hell broke lose.

[Texas Mobil 219]

I finaly move to a place where i could set up my Base. 148 gtl and a palomor 250 w/ a no ground Tram antenna. When i keyed up everything looked fine on the ol meter with the swr's and wattage. So i tried to make contact with some or locals. I keyed up two or three times with no contacts at all.

But it wasn't 30 minute the cops where next door. He never came over to the house but stood on their front porch on the cell phone looking over my antenna and mobil. Hmm make me wonder of i was bleeding over so bad they called the cop. instead of talking with my first. I just dont know.

Maybe i should of up up the A99 instead.

Any idea what might be going on with my base unit?

[shooter]

well there is a real good chance you were . how far apart are houses ? antrons are well known for bleeding all over the place . i would suggest asking your neighbor .
maybe there just wasnt anyone on the air at the time.

How about walking over and asking them. What a reality check..WOW!!!!

[TheTeZ]

definitively think you were bleeding, it doesnt take much, luckily my neighbor is kinda far away, when i key up with about 600 my lights all flicker, and i turn off the older tv's in my house. ... this is on AM only though, (the TV thing.)

But with 200 watts youll definitely still bleed, especially if your neighbors are that close.... it was kind of them to talk to you first about it though.

i just got my rfx 75 in the mail today, getting it installed this afternoon. i'm also getting a low pass filter and sticking that on there. i have an imax 2000, which a BIIIG antenna for an apartment. i'll be doing TVI tests tonight, and i'll let you know how good a low pass filter will work. (i'm only going to be putting out 100 watts tho..)

Twink let me know how it goes with the low pass filter.

I'm not bleeding on the neighbors, but I am bleeding on my TV's and computer speakers.

The best what i can put it is you dont have to run a earth ground. I works without it. Probably the very reason im probably bleeding on everything around me.

If the mod limiter in your radio has been disabled (clipped) or removed have it fixed. Keep your modulation level to a maximum of 100% on voice peaks. Ground all your equipment - power supply, radio, low pass filter, amp, meter, coax switch - anything and everything in the chain. Install rf chokes on all the power cords of your equipment (as close to the device as possible) to prevent rf from getting into the house wiring. If you have common mode current install a rf choke at the feedpoint of the antenna to prevent the coax from radiating.

[Red Warrior]

The radiation pattern and characteristic close to the antenna is not the same as that further away. The term near-field refers to the field characteristic close to the antenna; the term far-field refers to the field characteristic further away. The far-field is called the radiation field, and the near-field is called the induction field (although it also has a radiation component). Most UL certified electronic equipment is certified to be immune from RFI only in the far field. Almost no modern electronic equipment is immune from near-field (inductive) interference. To illustrate, take a magnet and hold it near the screen of your television. The resulting interference is inductive field interference.

Get your antenna close enough to your neighbor and run enough power and inductive inteference will eat them up and no amount of filters or grounding will eliminate it.

[TwentyTwo-Zero]

You make a valid point, but it is dependent upon a lot of variables. The suggestions I offered are good practice for any station - whether it is producing intereference or not. I live in a quadplex and have neighbors within 20 feet of me on both sides. My station includes the aforementioned preventative measures and I can run my amplifiers (on the appropriate bands) without causing any interference. Of course, my results are also dependent upon a lot of variables, but I see nothing wrong with giving advice that will make an improvement upon anyone's station...

Neither do I. My response was directed at Texas not you.

No need for a low pass with an rfx75 it has one built in...

[Texas Mobil 219]

This is my plan. Im going to go ahead and fly the A-99. Take the box out of line and just run the 148 barefoot. Get everything ground right (i knew better) and see what happens. Thanks for all the advice.

I feel that my 148 will work better with the A-99 any way. Just didn't have a pole to put it on. But i got some 40 to 50 foot trees that will do.

Ill let you all know how it goes this weekend.

['Doc]

An 'rfx75' has a low pass filter built in? Then there must be more than one version of that thing on the market, and the one's I've seen advertised don't have filtering built into them at all. Got a picture of one showing that filter?

Do what the guy said even with a a-99, ground everything, and as short as possible, less then 8 or 9 foot ground straps. Dont want to create a ground loops, a big mistake people make is putting up a huge tower, and running a ground wire down the ole tower to the ground..... why, the tower is metal is it not? And i dont think Rf will even go into ground in the first place . But even i run a ground, 3 8foot copper rods 3 feet apart in a triangle at the base of the tower, hooked to 1 leg, then the same thing behind the shack with a 6 foot aluminum ground strap going to the big amp. Also have my coaxes going through a pvc pipe in the wall filled with steel wool. Until i did all the above I would get rf feed back, probably from common mode, when the mic was just barely cracked, now i can crank it wide open ( which i never do anyways ) and it wont squeel. And if your putting the a-99 in a tree, i dont know if i would even ground it. Why make it more attractive to lightning, ground you station good and unplug the coax when your not using it.

I agree with everything above and more. I have done much of this and have ordered even more. I am searching for a good ground plane antenna that i can put up as high as possible. I am retired so i try to do most of my dxing during the day on 2watts swinging to ten peak hoping I'm not screwing up some old lady's soaps.
Some guys don't care but if your running 25watts and up I'll bet your bleeding on somebody.
I am using my own house as a test. A 500watt radio amp/tuner turns on when I key up, bleeds through my pc speakers and one of 3 direct tvs (old tv). If I'm bleeding on this stuff it's not good and I'm most likely bleeding on my neighbors. When and if I get my own house clean I should be ok.
For the guys or gals that don't care, just imagine your listening to your favorite radio or tv program and all you get is a bunch of hash and mash with cussing and swearing wiping out everything.
If I can't clean my own house with the best coax, good grounding, coax chokes, antenna hight, my good radio (148GTL) with just a variable and much more to come. I'm going mobile and when I wanna blow smoke I'll find a hill away from anybody I might bother.
I see so many people wanting more power. Put it in a mobile, buy a bigger alternator and have it properly set up.
I'm not bagging on base stations, I have one with the capacity for 200watts but I'm trying to clean it up.
3-4 watts with all the stuff mentioned above might and really mean might make you run clean.
Put your money in an awesome mobile. I probably will but I hope not.

No need for a low pass with an rfx75 it has one built in...

if it has one built in then it does a horrible job. i was shutting down tv's unless i had the filter on. anyway, the rfx blew 3 days after i had it installed anyway... what a joke.

[De_Wildfire]

I run over a kw and don't come over anything in the house. As for the neighbors, I made I was on good terms first, have a few beers, ect. ect. before I put my station on the air. That way, later if there is a problem, they will come to me first and see how it can be fixed. I am guessing the reason he called the cops on you is because your neighbor stays to themselves and didn't care to come over to talk to you about it. Your neighbor sounds like a real *****.

[slimstranger]

Yaaaaaaa.... What he said!

[EAGLE3836]

You could always put a Noise filter on your Nabors TV, if it dont work out........

Depending how many Nabors you Have though.........

My buddies Nabor dident call the cops,when he keyed up with his New 6 pill and bleeded over his TV, he just came over and cut his coaxl wire to his Antenna.........

Need less to say, no one speaks to anyone overthere.........
