The manual didn't say anything about high pitched whistles, and I have tried moving to different locations at home (i.e. where I got good reception before), all to no avail. Have you tried the radio several miles away from your house? If there is no whistle away from home, then at least you know it is a noise generated in your neighborhood. Fortunately, it doesn't happen all the time during a sitting, so I just turn the radio OFF, pause for a bit and then turn it back ON. That works.... for a short while. If there is no whistle when you turn the radio on, but then after a short while it comes back, it sounds like the problem may be with the radio. Also, have you tried the radio with and without batteries? That would tell you whether it is something coming over your AC power lines. Bob k5qwg Kindest regards, SW Newbie, Yerodin P. Thank you for responding Bob, Your suggestion (i.e. operating the radio with and without batteries), is well documented within the radio community. Before writing to rec.radio.shortwave, I tried it with no change in reception. Over the weekend, I will try operating the radio several miles away from my neighbourhood to rule out spurious signals specific to my area. BTW... Is trying different SW antennas using the KAITO 1102's external antenna jack capable of damaging anything? Prior to encountering my KAITO's problem, I have separately tried the following: 1. Winding the included external antenna around different forms (i.e. metal & PVC) 2. Connecting a 75 ohm coaxial cable via a plug similar to the antenna plug. 3. Using a TV signal booster + some coaxial cable connectors + 15 ft of cable in the hope that it would improve reception. (that was only mildly successful, but the radio functioned w/o issue even after that) 4. Using longer lengths of non-coaxial wire. I also tried wrapping sections of the whip antenna with aluminium foil. The hurtful thing is... the 1st month after removing my KAITO 1102 from the packaging, it intially worked without this noise.
