Hy Guy,
I I also have an azi loop on my workbench and hope to install it in about 4-8 weeks.
Have you already been able to gain experience in the HF range (3-30 MHz)?
Maybe the loops should be a little bit smaller. I've already thought about extending it so that you can switch between two loops.

Hi Christoph,
Yes, I've been please thus far with medium wave results. Besides the excellent nulling available 0-360 degrees of the compass, I am finding that nulls are generally broadbanded and similar to the Wellbrook K9AY phaser setup. This is very advantageous when living at or near the Pacific coast. I am able to orient directional antennas like these with the forward beam towards the trans-Pacifc DX, and all domestic (USA / Canada) signals are reduced to various degrees. This really helps the overseas signal carriers to have better S/N and a chance for audio & IDs.
Sensitivity of the Azi-Loop seems more than adequate for weak signal reception. At my location during the night time I am able to use the loop's 18dB preamplifier without any attenuation, or overloading.
Solar condx lately has made medium wave DX reception very poor. However, this morning's "dawn enhancement" boost was better than yesterday. There were only a couple Australian stations in audio (612 4QR Brisbane and 792 4RN Brisbane), but also a dozen or more carriers from "DU Land". These were noted in comparison to listed carrier frequencies with a calibrated Perseus SDR and Jaguar Pro software. Interestingly, I had anticipated Asian reception for my unattended recordings, and had preset the Azi-Loop's bearing to 310 degrees (Japan/Koreas). Perhaps if I had set the orientation around 240 degrees I would have had more Aussie stations captured to the SSD for later review.
My other SDR, a FDM-S3, works extremely well with this antenna also.
I'm planning to set up the Azi-Loop next week at a nearby seaside location (Grayland, Washington) and hope to have improved DX results due to sea gain.... and fingers are crossed for better propagation also.
