JRC JST-245

The Japan Radio Company JST-245 is an extraordinary rig providing 160 to 10 meter amateur band coverage plus 6 meters in all modes (AM/FM/SSB/CW/RTTY). The built-in automatic antenna tuner is provided as standard equipment. Tuner settings are automatically stored in memory for fast QSY. Three antenna connections are user selectable from the front panel and can be stored in memory. The general coverage receiver tunes from 100 kHz to 30 MHz plus 48 to 54 MHz. Electronically tuned front-end filtering, quad FET mixer and quadruple conversion (triple on FM) ensures excellent dynamic range (> 100 dB) and third order ICP of +30 dBm. Excellent I.F. bandwidth flexibility is assured with the variable Bandwidth Control. This permits the standard 2.4 kHz filter to be narrowed continuously to 800 Hz. Narrow SSB and CW filters for the second and third I.F. are available optionally. Other interference rejection features include Passband Shift (PBS), dual noise blanker, three step attenuation, I.F. notch, selectable AGC and all-mode squelch. Notch tracking is automatic. Once tuned, the I.F. notch filter will track the offending heterodyne (± 10 kHz) if the VFO frequency is changed. Very low phase noise is achieved through a single crystal Direct Digital Synthesis system. The keypad can be used for band selection or frequency input. The rear panel has three antenna inputs

The serious CW operator will appreciate the full break-in, variable CW pitch, and built-in electronic keyer. Two separate VFOs are featured for split frequency operation. Memory registers store most recent VFO frequency, mode, bandwidth and other important parameters for each band. Each of the 200 memories stores frequency, mode, AGC and bandwidth. A built-in RS-232C interface facilitates computer control. The heavy duty, built-in power supply insures reliable and continuous use. The ergonomic layout, colored LCD display and thoughtful placement of controls ensure ease of operation.
