Re: Carnation HF Loop Antenna non-functional

It’s certainly true that if the configuration is radio->feedline->tuner->ladderline->loop, turning on the tuner results in hearing more noise at the receiver.

What is not certain is that the tuner is creating noise, as opposed to doing a better job of getting the noise onto the coax when it is turned on compared to when it is turned off.

But when it was hooked to the loop antenna and turned on it did create noise.

It is not true that switching on the tuner introduces noise.  If we have the tuner on the bench in the shack, connected to the radio via a short feedline, we get no difference in noise when we power cycle the tuner.

There was a definite noise introduced when you turned the tuner on.  But it did tune the antenna.
