439.25Mhz Atv Downconverter Circuit


Posted on Jun 29, 2012

Most ATV (Amateur Television) transmitters transmit a DSB signal and commercial television stations use a VSB (Vestigial Sideband) signal. This fact is made use of in this converter to use the lower sideband. This results in less interference from repeaters that occupy the 440- to 445-MHz portion of the band.

However, this approach might suffer from VHF image responses from channel 29, if that channel is active in your area.
