Can you elaborate on that by perhaps a real world example or illustration?

This is a question I probably should have asked before I bought my current J-pole. But here it is: Is there any difference in reception or propagation in a 2 meter or 70 cm antenna that uses thin rod material such as that on an automobile antenna, vs. using a many times thicker, 1/2 inch...

I wouldn't no what to do with a coronal discharge device if my life depended on it. But here is an intertesting web site on the phenomenon: Corona Discharge

I understand now, based on your experience, why you think lightining protection systems don't work. Have you considered the distinct possibility that those folks in the 30's and 40's were victims of installers who had no idea what they were doing? Their bad experience "poisoned the well" of...

That's exactly what I was thinkin'. You nailed it! And as for snake oil, we may be surprised how many folks that stuff has "cured.":whistle: In any event, the lighting rod issue (whether they work or not) is beside the point of this question. Back to the question: Is there a need to...

Wrong. Lightining rods provide the path of least resistance for lightning to enter the ground through paths OTHER THAN the house. It is the same principle as providing the path of least resistance when grounding an antenna. Having rods in adjacent trees is not likely to reidrect lightning...

On a scale of 1 to 10, with 10 being "I'll shoot my eye out" and one being "go ahead and give him the BB gun", how much should I worry about an ungrounded antenna in my attic. I have professionally installed lightning rods all over my roof. But I am told even a near strike can charge the...

Goll-lee, Andy. I didn't know you could do thayat!

Sometimes we need to go with the information we got. I realize you were joking, but... Try this formula: Average rating divided by 1 plus the percentage below the median price of of all similarly purposed items. If the price of the item of interest is $65, and the rating is 5.0, divide...

Owning and using one of these units, I see no difference in safety between the way the AC is connected to this unit compared to any other, bannana plug or otherwise. And the ratings on eHam are the highest of any other power supply.

Thre are some programs that "prefer" to be located outside of the Program folder. I know that is the case with the Davis VantageVue Weatherlink program that interfaces with the data logger hooked up to my computer with a USB/Serial adapter. The program will appear to work for a few minutes...

Roger that on the heat. I had 4 of them randoming rolling around in my pocket. For a minute there I thought I was a liar because my pocket became hot enought for my pants to catch on fire. Luckily they didn't, but my pocket and leg got awfully hot. My next purchase was this nifty 8, AA...

I have a Kenwood HT with the optional BT-13 AA battery holder. It says "do not use rechargable batteries" on the unit. Why not? Will the voltage be too low? Will it simply reduce the output of the unit or will it do something worse? I am well stocked with Sanyo Eneloops. Why don't they...

I agree. I think this is just a case of getting to know the limiatations and optimum uses of your equipment. Image rejection is probably a weakness of most HTs. As someone on another thread said, HT's are also more susceptible to being overdriven by a strong signal than the typical mobile or...

"S" meter strength relative or not, the noise being picked up by the HT overpowered the squelch turned all the way up. And the noise did not touch the 710.

Here is where I am with my "hypothesis": I was surprised at the amount of unsquelchable noise picked up by the HT compared to the 710. Since I have the 710 in my shack that I will be using most of the time with the antenna in the attic that receives without the unsquelchable noise (RF...

I accept the fact that my active household circuitry is the source of my interference w/o turning off the power. Besides, I don't want to have to reset all my clocks.:headbang What antenna do you recommend for the 6a? I have an SMA to BNC adapter on order so I can change antennae w/o...

Usually new legal requirements pertain to the SALE of radios. They don't pertain to the OPERATION. I suspect 5KHz step radios will be in widespread usage for at least the next decade or longer. But it is a good question: Is it possible to transform existing 5 KHz step radios to 2.5 KHz...

OK. I walked around the house with the HT. The house is clearly full of RF signals of the sort that are not helpful to receiving clear signals. In most parts of the house, these unwanted signals (noise) are stronger than the squelch, even when it is turned all the way up. Some corners of the...

No, not the same antenna, but the S meters were both full. The 710 had a J-pole at eye level. The 6a had its rubber ducky at eye level.
