In the March 2001 QST Magazine is and article for the "Warbler" transceiver. It is a fixed frequency unit using 3.579Mhz colorburst crystals for its RF filter and operating frequency. Its RF pass band is based on the filter. There is no tuning for input frequency. This unit is designed to use standard crystals that happen to fall within international ham bands.
