This used hot plate was working near the high setting for a few hours last night until it was turned down from hi to setting of 8. Sometime during
the night it broke and stayed broke for about 16 hours..
During the daytime every five or so seconds interference in the bandwidth of VHF channel 2 (54-60 MHz) was noted on an analog television. Interference
was also noted on a frequency on 1.210 Mhz on a very sensitive AM radio.
The hotplate was the source of the interference because the interference on the am radio coincided with a clicking noise the hot plate makes. This
clicking noise is correlated with the start of heating when the hot plate is turned on. |
