I have been lurking here and reading the discussion which seems to me to have reduced itself down to a kind of "my daddy is better than your daddy" kind of thing.
The person who said the D104 microphone could be thought of as a voltage generator in series with a 500 pF capacitor hit the nail on the head! Exactly correct (although I thought it might be a *slightly* higher capacitance value). I have spent a few minutes with LTspice and made a plot which clearly shows what happens when you change the value of the load on the D104 microphone. With a 10 megohm load the -3 dB point will be right at 30 Hz. Please, fellows, take a quick peek at this plot: http://tonnesoftware.com/appnotes/D104loadTest.gif The bottom line of this note is that going higher than 10 megohms for a load is nonsense. Pure nonsense. - Jim W4ENE ______________________________________________________________ Our Main Website: http://www.amfone.net AMRadio mailing list Searchable Archives: http://www.mail-archive.com/amradio@mailman.qth.net/ List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Post: AMRadio@mailman.qth.net To unsubscribe, send an email to amradio-requ...@mailman.qth.net with the word unsubscribe in the message body.
