This SLM works fine and receives in Freq Range of 0 Hz to 3500 Khz Has good attenuator and mutiple impedance inputs. Perfect for DX ing the VLF Frequencies. Case has scratches but unit is in very good condition.I have logged many VLF Beacons with this RX. Pix on request. $100 and ship from Central Florida or meet you at Hamfest etc. Thank you Al
