Yaesu FT-891 Mode Mobile Transceiver - Radioworld

Product Information

Thanks for the comments. Thus-far there seems to be little experience of using the FT891 in the field.

Finally, the FT-891 has a good ALC Meter, which is imperative when running Data Modes. I see so many operators that are overdriving their audio and splattering across the entire FT8 spectrum. They're calling CQ and wondering why no replies when they are so distorted that the WSJT-X demodulator can't decode them! Learning to use your ALC is one of the key elements to being a responsible operator. The FT-891 fully supports the ATAS-25 and ATAS-120A Active Tuning Antenna System (optional) allowing for plug and play field and mobile operation. The New FT-991A now includes a high-resolution full color 3.5" TFT Touch panel for superior operability and visibility, incorporating a High Speed Spectrum and High Resolution real-time scope with ASC (Automatic Spectrum-scope control) built right in. Programming frustrations – It can be a challenge to program and customize the unit to your preferences, due to the small screen and some user interface quirks.Glad I did and recommend it to anyone who would like a quality, dependable and featured radio for any use, be it at home, mobile or portable. It takes less than 1A on RX and it seems like it's not so voltage sensitive, at least on my LiFePo4 batteries it's all fine. TCXO provides ±0.5 ppm High frequency stability (-10°C to +50°C) Stable 100 Watt Output The FT-891 provides stable 100 Watts (25W AM) of high power output. High reliability is assured by the transmitters careful circuit design with efficient thermostatically-controlled Dual internal fans and the die cast heat transferring chassis. 32-Bit IF DSP Provides effective and optimized QRM rejection The 32 bit high speed floating Point DSP (max 3000 MIPS) provides effective cancellation/reduction (DNR) of the random noise that is frequently frustrating while on the HF bands. The highly optimized AUTO NOTCH (DNF) automatically eliminates dominant beat tones, and the CONTOUR, and the APF, are very effective receiver noise reduction tools during HF band operations. USB Connection A native USB connection supports PC connectivity with a single cable, allowing for full rig control via a virtual serial port connection (VCP). Features for Ease of Operation • Large diameter Main Tuning Dial (1.6” / 41mm) with Torque adjustment

Improvements in DSP over the FT-450D are huge. The noise reduction actually works very well, with less tweaking. It is a welcome change. Some may complain that Yaesu's implementation of DNR is a bit watery-sounding, but I find a little DSP SFT (shift), and proper RF/AF gain removes most of the bubbling. I like it. Uncompromising Receiver Circuit Design Ensures Excellent Performance • Triple conversion with a 1st IF frequency of 69.450 MHz (SSB/CW/AM Loud, clear speaker – The built-in speaker provides clear, loud audio output, especially combined with this unit’s signal processing features.This radio is well recommended to anyone searching for a good reliable transmitter (mine does 94 Watts out on SSB from the box) and a good performing receiver (better than my old TS-480hx). After some extensive transmitting periods it gets warm to the touch, but not too warm, nothing to worry about. I use it on ssb with an antlion modmic and get nothing but good audio reports (once the TX equalizer is set to maximum performance).
