It sounds as though your unit has a problem. Do you have a manual and circuit ?? I can send you a PDF file if you need it as an attachment to a direct e-mail. The main problem that most have found is that the IF is 1500Hz so the note is rather high. There are a number of ways of converting that down including some soundcard software by Alberto of ARGO fame. 73 de ALan G3NYK alan.melia@btinternet.com ----- Original Message ----- From: "Alberto Riomao" To: Sent: 26 April 2005 21:03 Subject: LF: WG - selective level meter SPM-3 > Hello all, > > > I bought a very old and used Wandel & Goltermann - selective level meter > SPM-3 (selektiver pegelmesser 2~612KHz), but I think the filter is too > narrow, because I tune it in some airport beacons and I can not listen the > CW, only a high frequency noise. > > Does anyone know any modifications for this equipment?
