[This kind of discussion often happens over at TowerTalk@contesting.com. Search there for lots more info.] Keep in mind there are 3 types of "grounds": RF, AC (power), and lightning protection. (Actu

You can have a tuned "ground" but it only works at discrete frequencies. Besides, any current-carrying wire of appreciable length, tuned or not, becomes part of your antenna system. If, as it should,

The pic shows a TT 963 power supply, which is the one I happen to use. It is not included with the Orion. Any good 13.8 Volt, ~25 Amp supply may be used. My 963 is as quiet for RFI as I could want. M

Don't these numbers apply to "long" lines (many wavelengths and/or an exact multiple of a quarter wavelength)? I have been wondering about the following: If you have a short line, the loss should be

Maybe, but I haven't seen it listed for a long time. It was sold as a way to reduce interference (ingress) for weak signal TV reception, as you note. For Tx use, it would have a controlled impedance

Interesting idea. I imagine the existing code is built with licensed 3rd party libraries that could not be released in source. There's a big Xylinx chip in there. I suspect the only well-formatted do

All the recommendations so far are about treating the symptoms, not the cause of your trouble. You should not have so much RF in the shack. A balun or unun at your antenna and/or where your feedline

Seems to me that the open source software development for the SDR-1000 is a big plus with few negatives. You get faster development (more man-hours of development and test), faster bugfixes, and lots

There is no free lunch. Sometimes there is a "pre-paid lunch". Or maybe software development work is paid for out of current sales revenue. I.e., if they stop selling Orions (I or II), how much more
