Hello all. I'm new to this group, so forgive me if this is a silly/obvious question. While sitting around my apartment in Santa Clara, CA one day getting ready to move out here to Colorado, I was fooling around with my Realistic AM radio to see if I could pick up KOA, Denver (I could, but only late at night.) Well, this was around 5:00 PST or so and I found a VOA broadcast around 8500-9000 kHz (sorry - "slide rule" tuner). I can't imagine a MW broadcast of VOA would be audible in the bay area, but was it? Or was it some type of feeder broadcast? Thanks in advance. Once more, my apologies if there's an obvious answer to this one... -- =============================================================================== | ARPA: kucharsk@Solbourne.com | William Kucharski | | UUCP: ...!{boulder,sun,uunet}!stan!kucharsk | Solbourne Computer, Inc. | ===============================================================================

Once more, my apologies if there's an obvious answer to this >one... If it was an "AM" (i.e. mediumwave) radio, the signal would have been between _850_ and _900_ kHz.... What you probably heard was either an _image_ or an intermodulation product between the VOA signal and some other signal (combining and forming sum and difference frequencies, one of which just happens to fall in the mediumwave band). Remember too that there are powerful VOA transmitters at Dixon, CA which is relatively close to Sacramento and the Bay Area. -------------------------------------------------- Charles P.
