| FT980 | |||||||||
Overall Rating |  | ||||||||
| The FT-980 CAT presents a new leap forward in the amateur field, with the highest level of microprocessor control ever offered as a standard feature in an all mode, all soJid state H F transceiver. The transmitter sections operates in any mode, including full QSK CW, FM and FSK as standard, providing 100 watts nommai SSB output on all HF amateur bands. Yaesu's excellent RF speech processor is included lor SSB. along with AMGC (automatic microphone gain control), two front panel meters for monitoring multiple transmitter parameters, and an IF monitor. The MRF422 final transistors, rated at 280 watts each, are supplied with 24 V, allowing specified third order distortion products 40 dB down (at 14 MHz, 100 W output). Two independent receiver front ends, each with their own filter ban к s and dual, high Idss JFET amplifiers provide outstanding dynamic range and opt i in uni sensitivity for both amateur operation and short-wave DX listening in any mode, using two independent VFOs. The unique PLL design of the FT-980 incorporates a reference oscillator with stability of ±3 ppm or better from 0 to 40е С. The dual digital display system shows operating frequency the same for all modes, with resolution Lo either 100 or 10 Hz on one display, and to 1 kHz on the other; a scrolling "synthesized analog" sub display for the VFOs. The (SOC85-based) 8-bit microprocessor control system includes twelve memory channels which store both frequency and mode. Each of these plus the VFOs can be tuned independently using the tuning dial, scanning or keypad systems- The scanning system includes either two-speed scanning in 10 Hz steps, or single or multiple stepping in 5 kHz or 500 kHz steps. The keypad system allows convenient push button frequency entry, ±10 kHz TX or RX clarifier (offset) control, split frequency operation between the VFOs and a memory, and tuning or scanning frequency limit presetting. Additional standard features include a CW spotting switch, ALC meter peak hold for SSB, IF shift and IF width controls, IF notch and audio peak filters, 3-step receiver attenuator and provisions for optional narrow CW and AM filters, an optional internal electronic keyer, and true VHF and UHF frequency display when used with an optional transverter. Of course, when used with an optional Yaesu Interface, many of the transceiver functions can be controlled remotely by the operator's computer, including all VFO and memory functions, IF shift and width adjustments, mode selection, clarifier and FSK shift frequency selection, and more. Interfacing and computer controlled operation details are provided in the Interface Manual. | |||||||||
