If you improve your grounding system, you will always be happy that you did. To say it will or will not reduce noise requires knowing a lot more about the specific details of your setup. If there are
You know that many noise filtering circuits (for power lines, ethernet, RF and etc) use circuits the one half of which is connected to ground. Remove an effective ground connection and you degrade th
Its a common mis-conception that I run into professionally all the time. The fact is that unless the height of the vertical fins would be quite large, coupled with a large delta T, there is not enoug
Of course this is one reason for applying a choke to the outside of the feedline, at the antenna. 73 de Gary, AA2IZ of it and a of zero antenna comming
Perhaps one might consider that the design should handle the rated power without getting hot. Then this temperature rating would be moot. 73 de Gary, AA2IZ
Well now....a short wire that is too short to meet the stated requirement, would not in fact be resonant. That takes care of your first point. The second point is self defining....because if it is re
The Corsair is a fine radio. I have one. But as a contester, I am constrained to point out it has nothing like the front end selectivity of the latest units. So those (Orion, perhaps the "VII") would
It may depend on the physical layout of the heat sources. If they are concentrated in a few small areas, then a long, horizontal fin may more effectively spread the heat into a lot more fin area. If
If you are only a casual operator as you say, then the nice sound, simplicity, and old style feel of the Corsair may be for you. In a contest, you want the new rigs with the tight front ends, hands d
Doyle, I've seen two, exactly opposite, views on this. One view says yes, run them. The heat from the filaments is supposed to activate the getter materials and absorb any stray gas. Thus preventing
Duane, How did you accomplish that ? Did you have the means to shut off the high voltage ? Did you disconnect wires ? Did you run them in a test fixture that had only filament power (and a fan) ? 73
The Term Balun refers to a matching device that connects between BALanced and UNbalanced systems - hence the name. A balanced load would be your dipole for instance (in an ideal world of course). An
Bill.... Cebik writes very extensively on these matters. Much of his work can be found on the web. You will find just what you want, and many practical designs, in his work. I suggest you look into h
Cebik has designs for Baluns (and Ununs) with many different impedance ratios. Palomar Engineering or Amidon still making made to order specialty baluns. A 4:1 would be about 25% less effecient or po
I don't think an inverted V is inherently better or worse in this regard. The Coil type Balun right at the antenna will in fact choke off currents from flowing at that point on down the outside of th
