That is why you should disconnect the antenna at the radio input, silly person. {+_+}

Use your imagination. I walk around until I see something that will work. A coil of polyethylene plumbing tubing could probably add enough beef the result could be stood up or hung and still hold a ci

Loop Best Practice Re: Genuine YouLoop vs. clone YouLoop
The loop impedance is (puns intended) complex. The resistance portion is tiny. The reactance component is very high. So matching the antenna requires some imagination due the huge imaginary components

Just grab the edge of that panel and open it out to the right. Then you can adjust until it looks right. {^_^}

Loop Best Practice Re: Genuine YouLoop vs. clone YouLoop
To put it bluntly and simply, as long as the noise increases by mid single digit dB or more when you connect the antenna vs a dummy load, improving the antenna SWR will do nothing for received SNR. It

Is there a noise reduction tool running on the community edition that is not in the regular edition? That will give a warbly effect. {^_^}

Tape it to the sun screen. But don't fold it up. That will fatigue break the conductors. {o.o}

Find some thin tubing that can be formed into a loop using a heat gun. That can be used as a form for the antenna. {^_^}

Probably not. As I mentioned I live in a horridly noisy area. And our largish solar array, UPSs, computers, and networks do not help. {^_^}

I think you're on target. For a transmitting loop you probably want to make it out of copper plumbing pipes. (I suppose copper plated would also work; but, who makes it?) Then you need a way to match

That's fine as long as the people purchasing prove to themselves it will be worth it by replacing their youloop with a short or dummy load and have the received noise drop several dB. If received nois

There is little point to making the switch. In order to use special features the program using it must change to use new API entry points. About the only worthwhile change in past years has been sligh

Speaking of old analog designs, dig up descriptions of super-regenerative receivers. Imagine what they do when two of them are near each other. Modulate one of them. Do you hear it in the other? What
