| - | ===== Description ===== | ||
| - | Provides Models [[540]] and [[544]] transceivers with transmit and receive capabilities on 160 meters. Crystal controlled mixer converts 1.8 - 2 MHz signals to 3.5 - 3.7 MHz which are then tuned in the 80 meter mode. The crystal oscillator also mixes with the 540 / 544 VFO signal to provide proper injection for the transmitting mixer in the transceiver. A low pass filter is switched into the antenna line to reduce harmonics. Power input is reduced a nominal 25%. Panel switch also selects the two transceiver crystal channels when fixed frequency use is desired. Includes cables (less crystals). Housed in matching enclosure. | ||
