Very good selection with cascaded 250 Hz filters. Can be narrowed down to less than 100Hz by band pass tuning. Most "Yen boxes" have additional built-in attenuators in the LF/MF path and the sensitivity improves by 20 dB or so if you take them out. Normally this creates no problem if you don't live in proximity of a LF/MF broadcaster (My QTH is about 40 km from Sottens on 765 kHz) 73 de Toni
