YAESU FT-991A Transceivers

FT-991A covers shortwave to UHF frequency bands and is a compact transceiver with full frequency band and full mode. Including a high-resolution full-color 3.5-inch TFT touch screen with excellent operability and visibility, and a high-speed spectrum and high-resolution real-time oscilloscope combined with the built-in ASC (Automatic Spectral Range Control) function. Using such a transceiver that condenses a variety of essences, you can fully enjoy the infinite charm of amateur radio.

• High brightness full color touch screen

• FT-99IA is equipped with a 3.5-inch full-color TFT high-resolution touch screen, which can clearly display functional information including receiving frequency band, noise and signal interference suppression tools. The operator can quickly grasp the status of each function even in the accurate operation state of DX and the game.

• Configure C4FM digital mode

• It supports Yaesu's unique C4FM digital communication mode, with good error correction performance, ensuring superior performance in mobile communications and providing high-quality digital audio transmission. The AMS adaptive mode can identify the transmission mode of the contact station and automatically switch the radio to the same communication mode as the received signal.

• Built-in two smoothing filters

• FT-99IA is equipped with two narrow-band smoothing filters, 3kHz and 15kHz, which are mainly used in very busy frequency bands during competitions. It can significantly reduce the strong interference signals outside the frequency band at the first intermediate frequency, and reduce the influence of these signals in the second stage to further Optimize the dynamic range and IP3 characteristics to handle weak to strong signals.

• Powerful IF DSP

• The receiver uses Texas Instruments' high-speed computing DSP chip TMS320C6746, which ensures high-speed operation in real environments. It can show excellent carrier anti-interference performance in HF/VHF/UHF bands, effectively reducing QSo in DX and competition environments Communication pressure.

• Reliable high power amplifier

• In the HF/50MHz frequency range, a pair of RDIOOHHFI transistors in the push-pull radio frequency amplifier device can provide 100W low distortion and high quality output power. The final power amplifier in the 144MHz/430MHz frequency band uses the high output power RDH70HUF2 device, which can provide a large output power of 50w.

• High-speed antenna tuner

• FT-99IA has a high-speed digital tuner with built-in relay switching, which can cover the amateur band from 1.8MHz to 50MHz. 100 sets of large-capacity channel tuning data storage, which can be used immediately under conditions that match the previous tuning frequency.
