You were very lucky! Those ribbon cables are delicate, and very hard to re-insert without damaging them. I would recommend not disconnecting them Sun, 31 Jan 2010 12:32:43 GMT Julian Hardstone http://groups.yahoo.com/group/de1103/message/2435 http://groups.yahoo.com/group/de1103/message/2435 The DE1103 does not have a 'BFO' in the tube-era sense, it has a carrier insertion oscillator (CIO) and a proper balanced mixer (demodulator) for SSB.

[...] Moises, did you check if the noise is heard also if you tap the audio from the line out plug? This can indicate if the problem is in the audio amp Thu, 28 Jan 2010 01:29:44 GMT kb8dns http://groups.yahoo.com/group/de1103/message/2431 http://groups.yahoo.com/group/de1103/message/2431 Hola Moises. You are describing an audio problem and I would think it would be associated with the audio circuit since you are hearing it.
