A tuned loop for FM? Apart from the usual "folded dipole", loops are quite uncommon up there. Honestly, that sounds more like an AM loop.
I also have a big homebrew one, square and a good 3 x 3 ft, uses one half of a 2x 500pF mechanical varicap. Big signal, but very cumbersome. The Tecsun is much better suited for my purposes really. Mine can still be peaked all over 160m, too - that gives some nice reception there on the ICF-SW7600G with half-inserted antenna jack trick (same should apply for DE1103/E5 which use the ferrite rod up to 3 MHz). That is, provided all the local QRM sources are off (quality energy-saving bulbs tend to be OK at some distance, conventional fluorescents are worse, and TVs are just EVIL).
One of these days I should build a tuned loop with preamp for the low shortwave ranges. The AN-LP1 is only useful from about 3.5 MHz up, and the Sony sets use a broad band filter after the ferrite rod so that's not too much use beyond 2 MHz. Not good for 120m or 90m.
