Hello,
I have recapped my Beomaster 1900 and have some problems with it.
Currently I am just trying to understanding the following statement in the manual.
I think that maybe something is lost in translation that I do not understand.
"DC Voltages without bracket are measured with the receiver in position FM 5 and aerial signal 500 uV (1 mV EMK) with pilot signal."
I'm trying to determine what signal to put into the aerial connection. Is this a square wave or sine wave ??? I assume it is 1mV peak to peak. And I am not sure of the meaning of piilot signal.
Thank you for any help.
No, no, no.The signal mentioned is to come from an FM signal generator capable of producing a controlled "antenna-like" signal with carrier and modulation (not just an AF signal).In other words, the signal has to be FM (Frequency Modulated) and have an amplitude as stated (and modulation as stated and/or necessary).The pilot is the 19kHz multiplex (MPX) for the stereo decoder (read: the signal that codes (or "chops") the incoming signal up into left and right channels respectively.

So, in general can just tune into a station and assume the measurement calories listed should be close?
Eh....Not exactly, - but of course tuning in to a known FM station will give you a general idea about the condition of the tuner.
