Well, more like playing around... First, I tried an old ferrite antenna from a friend's junk box. Placing it near the internal ferrite actually worsened reception. So a quick-n-dirty augmentation to the ultralight didn't work.
Second, I tried my Radio Shack loop. The SRF-59 liked being inside it, but it was happiest at the center of the loop. Obviously this requires some dexterity and juggling if you're going to do serious nulling and loop tuning. Finally, I placed the SRF-59 on the loop head of my Quantum loop. This worked the best, both ergonomically and electrically. The Quantum gave good directionality/nulling, selectivity, and ease of movement. Velcro would take care of stability. Not surprisingly, there was no difference between the loop switched on or off. The Quantum threatened to overload the poor ultralight, so I had to detune the loop away from the radio's frequency. Testing was on 570 to test nulling a semi-local, WMCA. R. Reloj was actually dominant, so most of my jiggering was aimed at nulling Cuba instead. Also dominant was Rebelde on 560. Another testament to the DX powers of this amazing little rig. Testing was conducted while drinking a snifter of cognac, so caveat lector.
