Regarding 300 to 2800, or 100 to 3400, or whatever, I want to bring to the surface another factor.
One of the reasons the usual inexpensive low-end SSB rigs can sound so obnoxious is that they have a poor low-end response, as pointed out by several folks. Another reason that even moderate-priced SSB rigs can sound bad is a sharp cutoff rate at either the low-frequency end (say 300 Hz) and/or the high-frequency end (say 2800 Hz). It is the sudden cutoff that the ear dislikes. I point out the my old 51J4 sound pretty nice if the mechanical filter is kicked out. Why? Not only because of the increased bandwidth of the I.F. but rather because the shape of the top of that filtering system is so rounded. The cutoff of the audio frequencies is quite gentle. Not all that wide, but the descent into the stopband is pretty gentle. - Jim W4ENE ______________________________________________________________ Our Main Website: http://www.amfone.net AMRadio mailing list Searchable Archives: http://www.mail-archive.com/[email protected]/ List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Post: [email protected] To unsubscribe, send an email to [email protected] with the word unsubscribe in the message body.
